Today, upon checking some eSports sites, I came across this motivational poster:

So inspirational -sigh-

For those of you not familiar with Starcraft pro-gaming, Lim Yo Hwan is a professional gamer who played since the BroodWar days.  His ability to control (micro) and tactical smarts allowed him to take what was viewed as the weakest race (Terran) as his weapon.  In short, he’s the legend of Starcraft as an eSport.

Back to my adventure on the internet.  What does America have to offer?

So I’ve been busy lately because I was organizing a live event for the finals of our Starcraft II tournament.  Here is a pic of our turnout:

All seats taken, standing room only

This surpassed our expectations, with over 120 people in the room, despite there being a basketball game (sweet sixteen) that night.  Let me introduce our players:

For third place we have

FGiSignals, playing as Protoss, and his opponent:

llamma

llamma, also playing as Protoss.  Both players are in the top of their Master League divisions, and are some of the best in the school.

For 1st and second place, we have:

VaiOZ

VaiOZ, a terran who went from prelims to the finals.  He plays against:

aechmil

(In the foreground)  Aechmil, a master league #1 Terran player.

To guide us through the night we had Doppler, our founder and excellent SC player, with Heyoka from teamliquid.net working the camera

also casting is our current president ObiWan:

The replays are here. Our next step?  A larger tournament 🙂

So these weeks have been pretty hectic, and some things have come up. The bad news first is that my VODs will be delayed because of some recent development. The good news is that this recent development is the fact that I have been appointed an officer in the SC team at my school, and I have the plans to organize a huge tournament at my school.

This is something I am really happy for because I am able to advance esports in the school, and hopefully the US as well. The VODs will be up, just not as soon as originally planned. There are some really good games, and I will also plan to cast our tourney games as well. Stay tuned for updates!

Art of Meta

People often talk about the “meta game” in strategies, but it is often ignored for lack of better understanding.  In this article we will discuss what is the meta game and just how important it is to a strategy.

What is the meta-game?

Meta- comes from the Greek word for “after” or “beyond”.  A Metagame is the gameplay that extends beyond the game.  Of course this sounds like a conundrum, and is better explained using examples:

– Your attack fails and you lose your entire army.  The opponent has a very large army and starts attacking your base.  You leave the game.

In the above example, we notice that the game does not in fact play a large role in your response.  In our example, the conditions for defeat are to lose every building.  You did not fulfill this requirement, but was willing to leave the game nevertheless.

Many actions in Starcraft are in fact justified not by the game, but rather observations and inferences made by the player.  Perhaps the easiest way to learn what the meta game is, is to define what it IS NOT.

In Starcraft 1, Vultures were very good against Protoss. This is not a meta-game aspect.  By definition, Vultures had high speed, spider mines, and allowed a decently skilled player to out micro slower and more significantly expensive zealots and dragoons.  Units do x amount of damage.  Upgrades aside, a player’s reaction does not change how much damage the units do.

Meta game is not micro, nor is it macro.  These will later become constituents of it.  Micro is only effective as the units’ speed and fire rate, and macro depends essentially on harvester number (and smaller factors such as distance to mineral patch and saturation).  Generally speaking, anything that has a number in the game associated with it is not meta game material

Meta game can be defined with aggressiveness or defensiveness, cautiousness, hesitation, or even Tilt. It is the mindset regarding decision making, of both you and your opponent(s)..

How to utilize the Meta-game I

“It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.” -SunTzu

The first part of utilizing the Meta Game is to understand your own reactions and thoughts.  This serves many purposes all of which are useful to mastering the Meta-game:

1. Understanding yourself will show the determinate “motive” behind your strategies.  With each motivation, there are weaknesses.  For example, aggressive players are often very focused on the frontline micro, and often forget about their base and are vulnerable to zergling runbys.  Defensive players often will often give up map control.

2.  Understanding yourself and your reactions will let you learn what other people feel and react.  This simply comes with experience.  The purported “game sense” of certain players is simply personal experience that something is going to happen given certain indicators.  Again, this comes from experience, and will only come by playing more games

3.  Knowing your usual response allows you to consciously fight bad habits and train yourself in good practices.  For example, I played defensively at first, waiting for the enemy to come to me, and often ended in disaster.  However, but realizing this, I learned to send more scouts, and not fear the enemy as much.

Humans often think very similarly, and because of that, simply knowing how you think during certain times is a window to how others will also think.

How to utilize the Meta-Game II

“All warfare is based on deception” – SunTzu

You understand how you respond now.  After some practice, you know how not to despair, which battles are winnable, when to be aggressive, and when to be defensive.  Now here is the hard part:  You must play with your opponent’s mind.

1.  Fear- an enemy who is afraid or nervous will make poor choices.  Some early aggression will often do this trick.  Drops and harassment often times, while not damaging to the units and structures, will cause the opponent to miss timings, lose focus, and be forced to think on the fly.  If he cannot, he will be very far behind.

2.  Confusion- Starcraft is a reactionary game. Many people (mistakenly) think of the game as a game of glorified rock-paper-scissors.  This thinking is wrong on many counts.  Perhaps the obvious flaw in this analogy is that rock paper scissors requires you field your units at the same time.  To win at Starcraft with this ideology (my units counter yours), you need to field not only the correct unit at the right time, but also in the right locations, in the right amounts, not even counting what will happen after the battle or such.  Hiding your unit composition or misleading your opponent in unit composition will lead to his demise.

Denying scouting is ever so crucial to sowing confusion.  Denying any form of scouting basically forces the opponent to play blind and rely of either luck or hope, neither of which are viable strategies compared to you having map control and army advantage.

3.  False hope – Often times the game changer isn’t just the action, but the magnitude.  People leave games because they lose their entire army, or they lose all their workers.  It is the differential that often matters.  To make sure the differential is maximized, sometimes you let the opponent go about his way, despite his impending doom.  This is especially devastating for Zerg players, who believe they are safe to drone up, only to lose their entire army very shortly.

Perhaps the Meta-game is the center of such celebrated “creativity” like that of TLO.  We will revisit this subject in the future, delving into specifics.  Our goal with FleetBacon gaming is to experiment with strategies beyond the game, so the meta-game is of great interest to us.  Stay tuned for future updates.  Next time: Reapers!

Perhaps one of the most overlooked aspects of Starcraft is the map itself.  There are many reasons for this, but try and think to yourself, when was the last time you consciously thought the map was a central part of your strategy?  Did you know where the expansions are in the map?  Which locations can be abused by different races?  In this series, we will analyze the different maps and see how seriously maps play into strategy.

Our first map is a classic:  Lost Temple

The map in all its glory

It has become a mantra for many players to say that this map is imbalanced for Terran from several sources, including but not limited to the music video “banelings”.  However, not many people understand why this is the case.

This map has an interesting history.  Back in the day, when Starcraft was still young, many games simply relied on one-base play.  Building a second command center/nexus (hatcheries were a separate case obviously) was seen as a way to either stay in the game or a waste of 400 minerals.  What Lost Temple introduced was the concept of a “natural expansion”.  Situated outside of the Main Base, down a ramp and only (for now) accessible by a narrow choke, this location was:

A.  Fairly close to the main base

B. Easy to defend

C. Can be assimilated into the main base

It did not take long for players to realize the previously thought “400 mineral doorstep” known as an extra base might be worth the investment.  First of all, if both players turtle and their main became depleted of the minerals, the player who can hold their natural expansion while denying their opponent of their natural expansion should simply outlast their opponent.

The beauty of the natural expansion, however, was not as a replacement base, but rather as a benefit when taken in conjunction with their main base.  This would double the economy, allowing twice the amount of production to take place, and to put it simply, you can win by having more stuff than your opponent.

Of course, we are not here to specifically discuss expansions in depth, but the point is Lost Temple reinforced the notion that a well-designed “natural expansions”.  So important were these “naturals” that some players took extreme measures to defend it (Sean Plott, Daily #100).  Interesting plays were evolved such as players sacrificing an early army to “fast expand”, especially with Zerg as they needed an additional hatchery to macro efficiently either way.  Natural expansions soon began to become implemented as a standard map design component.

While not our focus, expansions is the reason this map becomes interesting to play on.  While listed as a 4-player map, the small(er) size of Lost Temple lends itself to be used more commonly as a 1v1 2-player map.  This has several implications:

1. It is up to the player to determine the location of their opponent.  Initially, there is a a 1 in 3 chance of finding the base, after which there will be a 1 in 2 chance, before simply deducing (but still requires scouting) the location of the opposing base.  This is an example of a temporal and probabilistic buffer to early “cheese rushes”, as opposed to physical buffers such as destructible rocks.

2. 2 vacant base locations provide 4 reasonably well-defended expansions. The only way to access these bases by the ground are through the narrow choke points.  Furthermore, taking the low-ground “naturals” will more or less deny the high-ground “Main” expansion from the opponent.

3. Moving closer to our next topic, controlling bases on both sides of a gold expansion will essentially protect it by virtue of zoning (we will discuss this phenomenon later).

So far we notice that the emphasis on this map is on expansions:  There are no back doors on bases, and each base location can be well defended by the minimum defenses, or in other words, the locations can maximize a base defense.  This is the phenomenon of zoning. Zoning is similar to the concept of a concave, where the units are in an arc and are all capable of firing, maximizing damage.  Zoning usually pertains to positioning static defenses so that there are regions where, all the defense structures can fire.

For example, missile turret placement in a mineral line.  Single Missile turrets alone are ineffective against a harassment force, a line of as little as 3 turrets are deadly against air.  3 turrets in a line are of course, much more effective that 5 or 7 randomly scattered turrets, thus reducing the cost needed to defend the base.  The deadliest region, or zone, of the missile turret line is a path perpendicular to the turret line (analogous the the focus of the arc in a concave).  This region will be avoided by smaller forces, and must be aimed properly.

On lost temple, we notice several locations where static defenses can be used/abused, and where armies can make excellent defenses by virtue of zoning.

A single bunker or cannon on the high-ground outcrop can protect both the ramp and the expansion.  Adding more defenses can make a larger and more effective zone.  This is due to the fact that a high-ground outcrop can do damage over a wider range, and not be counterattacked for awhile, and also the fact that the choke point limits the opponent to move into the effective range of these defense.  This is a deterrent, and in another way of thinking, a stationary building causes your opponent to move where you want him to, at least for the early-mid game.

What a single, well-placed defense can defend

Of course this zone can be bolstered with overlapping defenses and army units, but this just shows how Lost Temple provides excellent defense points that allow for expansions that can be easily defended.  Furthermore:

Benefits of taking adjacent expansions

The x’s indicate where a defensive army/structures might be positioned after taking adjacent expansion.  Although there are only 3 bases, we observe 2 things:

1. The unoccupied gold expansion is now defended

2.  The unoccupied high ground adjacent to the 3rd expo is secured.

Simply put, taking and defending an adjacent natural defends the gold expansion and the high-ground! That being said, this expansion is critical in a macro-war, as the great defense of these potential 5 bases can be abused if the opponent does not choose their expansions wisely.  Zerg players have found that simply spreading the creep to the front of their natural and placing spine crawlers there also accomplish the task of defending the gold.

Expanding to the high-ground, however is not also without merit, due to longer ground rush distance.

To even get to a close-position base on Lost Temple is convoluted, despite giving an impression on being an open arena style map.  A good way to quantitatively observe the hampered rush distance can simply be given by the Rush constant:

(Shortest Distance to location A by ground)/(Distance to location A by air) = Rush constant

An ideal map for rushing will have a constant = 1, but a higher Rush constant means that to move on ground to said location, more time will be required.  Lost temple is such an example, so to scout out a hidden expansion on the high ground would require a scout to travel to 2 possible locations in a convoluted path.  This is usually seen as a waste of time, and often completely overlooked.  However, access to better scouting will negate this benefit.  Zerg with proper overlord placement, or extensive pylon placement can spot the hidden expansions easily.  Making the high ground hidden expansion appears to be more so a gamble as as the risk is greater than that of taking the adjacent low-ground expo.  Hidden expansions, however, are still viable strategies in the right situations.

The illusion of an open arena-style map is caused by the narrow chokes and also the central pillars.  Large armies will have to either split apart when passing the columns, or stay together in a single column.  Neither of these scenarios allow effective use of the army.  However, just outside a base, in between the pillars, are open regions.  These regions allow the formation of a larger concave and freedom of movement.  Until air units are around, an attacking army is hampered by the map until it passes the pillars. This can be further exploited by controlling the watch towers to observe when an army is advancing down the center.  However, it should be noted that this “defender’s advantage” can easily be turned because if the open region outside a base is taken, the attacker can now have stronger unit positioning, because the defender is forced down his own choke point.  This contain becomes exponentially more effective as the defender is pushed farther back, up their ramp.  Many games have been won on this map because of an effective contain on this map, regardless of race.

Air plays an interesting part in Lost temple.  Air negates the rush distance convolution, but is weak to strong defenses.  There are 4 ways air units are effective on this map:

1.  Shorter transit distance.  This makes reinforcements by air arrive faster than a ground reinforcement from the opponent.

2.  Ability to use map fringes as (usually) uncontested ground.  Ground units have to pass through the center of the map, which will invariably have the enemy presence.  Air units can avoid such detection and resistance.

3. Island expansions

4.  High ground regions in good locations are accessible only by air.

Outside every natural expansion is such a high-ground.  Early drops on this high ground can not only deny expansions, but also set up a later contain.  The pillars in the center of the map are a great way to obtain both vision and post guards that can harass incoming armies.  Perhaps, the things that benefit best from excellent high-ground locations are stationary defenses.  These do  not occupy supply and do considerable damage, and can deny ground positions and even give vision for quite some time.

Islands are an interesting game mechanic, which we will cover later in this series.  Essentially, island expansions tend to be hidden and inaccessible to ground forces.  This provides, in terms of gameplay, a natural defense.  Island expansions rarely have extensive arrays of defenses (except for air), and are not easy to bring a large army to.  Islands are in short both hidden and protected expansions.

The fifth air unit benefit is so important that I placed it in a separate topic.  Dropping and preventing drops are crucial due to several reasons.  Drops can utilize high-ground otherwise inaccessible.  Drops can destroy island expansions with impunity.  Drops that are performed when the opponent is out of position will be even more effective due to the longer rush distance.  At the distal side of the ramp in the main is a region that is often out of sight of the opponent (they will be focused on the ramp), or the hiding location for hidden tech buildings.  Either way, this region is a prime drop zone.  This region is even better than above the mineral line because simply there is no room behind the minerals.  The open region allows better maneuvering of units while being close to the minerals, and allows the dropship/warp prism/overlord to loiter in safety, allowing a safe retreat. Thus, an emphasis on defending against drops in this map is highly recommended when required.

So why has this map been notorious for Terran imbalance?  Let us look at what Terran can use their advantage on this map.  Terran has no issue taking the island expansions, they simply require a lift-off of the command center.  Some strategies become extreme to the point where the Terran player immediately takes an island and immediately starts teching up.  This works because the initial scout is unable to locate the player, and the Terran player can forgo tier-1 ground defense.  Medivacs are almost present in a Terran army, giving them no pause to abuse high ground positions.  Along the same lines, tanks are a staple unit in most Terran armies, and can be used effectively to set up a contain, or be lifted onto the high ground to deny an expansion.

Does this make Terran overpowered? I argue no, because other races can also use and abuse this map’s advantages as much or even more so than Terrans. The trick is to think of this map similar to an island map, to go expo-hungry and use static defenses to bolster your position while relying on drops to minimize transit distances.  Of course, ground units and early pressure are still powerful, but this map has strong defensive positions, and as the mid game progresses (and where “imba” supposedly occurs”),  we find that drops become more powerful for several reasons.  Many times, the army will be out of position.  Islands are taken, but are weak to drops.  Building placements at the main may even hinder the army from proper placement to repel a drop.  For mid game, it perhaps is imperative to drop or anticipate drops on this map.

That being said, Protoss should use warp prism more, warping in zealots to harass the mineral line.  Zerg should nydus.  The high-grounds, islands, and distal locations work for all races!  By going air, we are able to both drop, defend against drops, and have very short transits between bases.  Of course this must be taken with a grain of salt, as ground units are effective as well.  Aggressive players should try and force a contain in this case, but unless a contain is complete and advances, a good player can defend and perform a drop, which will devastate the economy and catch your units out of position.  Expand wisely, choose good unit positions, and control the map.

This has been an analysis of Lost Temple, and more analysis will come later.  Perhaps even this map will be revisited with future patches and gameplay.  Remember to take the map into consideration for your strategy!
