Here is the second half of the SCCAIT round of 8. Today I’ll go over the later 2 matches of the 4, from the second video.
Bereaver vs XIMP
The newcomer protoss Bereaver versus the old school carrier bot XIMP.
XIMP always cannons itself in and goes carriers. The strategy seems easy to counter, and yet somehow it is not so easy; XIMP is still highly successful. I think protoss has the most difficult time countering the carriers. Terran can make tanks and blast down the cannon wall, and zerg can stop the carriers and prevent all expansions with hydralisks. Protoss has counters too, but they are not as simple to execute.
In game 1, Bereaver opened with two gates. On seeing the cannons it had the sense to immediately start its own natural and soon take its 3rd as well, pulling ahead in economy. Bereaver added some scattered cannons of its own, which seems strange and inefficient to me, but also got templar tech and started storm research, which is good play.
When the carriers arrived, high templar apparently did not yet have storm energy. Bereaver caught XIMP’s third starting and stopped it, which was necessary, but had made too many zealots and cannons and not enough dragoons, which was not promising against carriers. If Bereaver had mineral excess and gas shortage, then it probably should have taken a 4th base sooner.
But Bereaver did get a 4th soon enough, built more goons, and with help from some poor tactical decisions by XIMP, defeated the carriers using dragoons and storm. Bereaver had held off the carriers and stopped expansions, so it won.
Game 2 followed a similar course, but XIMP’s carriers took the long way around the map and XIMP successfully started a 3rd base (on its second attempt), while Bereaver saw nothing and opted to attack the cannon wall, setting itself back. Bereaver ignored the 3rd too long and XIMP got cannons up there, while Bereaver didn’t spend its extra money on a new 4th base after losing its first attempt to the carriers. Bereaver’s game plan failed and XIMP won.
I noticed movement on the minimap which looked like a failed reaver drop in XIMP’s main, but we didn’t get to see it in the video.
In Game 3 Bereaver got confused by the map, Heartbreak Ridge: It sent a probe to take a 3rd but was unable to navigate the mineral block. The probe wandered aimlessly. “This way! No, it’s closed off. This way! No. This way!” Bereaver went down without much fight.
XIMP, by the way, understands mineral blocks and is able to mine them out. A bot has to do a lot right to play well, and XIMP does a lot right. Bereaver is strong but doesn’t quite have the same robustness.
Krasi0 vs Tscmoo protoss
Krasi0’s game plan is to expand and build up while holding off any attacks with efficient terran defense, then move out with a large force that is difficult for any enemy to oppose directly. Tscmoo protoss is unpredictable, but it has played many games lately with ceaseless pinprick harassment. The clash of styles between two top bots promises to be fun!
Game 1. Tscmoo opened with scouts, expensive units with powerful air attack and puny ground attack. On the one hand, objectively scouts are poor at harassment. On the other hand, opponents have proven weak against widespread harassment and protoss has few other options for it. Tscmoo has won games this way, including against Krasi0.
As the game went, the scouts stopped mining at Krasi0’s natural for too long; air defense took a while to kick in. Tscmoo quickly went up to 5 bases with a fleet beacon to upgrade the scouts and shuttles with reavers to add firepower to the harassment. Krasi0 was satisfied with 3 bases for the time being, which seems fine to me.
Well, Krasi0 built many turrets and had good enough positioning, and Tscmoo’s harassment achieved nothing. Krasi0’s first push won outright. Oh well.
Game 2. This time Tscmoo went dark templar. Krasi0 the strong defender was of course prepared, and the dark templar never got close.
Tscmoo followed up with arbiters and researched recall. Arbiters started flitting irregularly across the map looking for openings, but Krasi0 had again built many turrets in its main and there were few openings to find. An arbiter finally recalled the 3rd. It stopped mining for a time but was not fully successful because the zealots in the recall did not feel like giving their lives for Aiur. Units with no escape route need the all-in mentality: “Die I must. Let me sell my life dearly.”
Krasi0 pushed out and started taking down bases, and Tscmoo never made a strong move to defend itself. Arbiters flew around stasising random units but not firing. Krasi0 built an absurd number of turrets but was too far ahead to suffer from the needless expense. Tscmoo's play was not focussed enough to make progress; it came across as scattershot and ineffective. Of course, that is largely because Krasi0 defended with cautious thoroughness.
Next I’ll cover the round of 4, likely tomorrow on the same day that the finals are broadcast. I didn’t catch up with real time after all.
