Favor Chess AI vs Chess Evolved Online AI - Gameplay Round 2

작년

Ai Showmatch 2

The second round is ready! This time, the games were played in a best-of-three and a slightly different army was used. In order to see all the rules for the first round you can view the first game's steemit post (all of which except the army used carry over) Game 1 Post

This time the army features a queen instead of a bishop, so it's a little more power on the board to work with for both sides. It did actually result in more dramatic games.

In this video I show both of the game windows, which is good because sometimes the game can end in CEO before it does in FC. The previous video only showed the Favor Chess viewpoint. For the exercise, I have one window open with each of the games and use the moves the AI plays in one game against the AI in the other game. I've also edited the video a little to make watching better and keep track of the score between rounds.

Version .54 of Chess Evolved Online improved the AI in the game in some ways, and it makes a few stronger moves. There were no dramatic changes since .53b, aside from understanding more attack and piece types that aren't part of this showmatch.

Rules:

If the game ends in either game, it counts as a win for the player who won on that game.
If the game ends in a draw in either game, it counts as a draw.
Domain will be turned off in Favor Chess.
No game clock.
The game will use a slightly modified chess setup that replaces the queenside bishop with another queen.

Well according to stockfish, in game 2 the two biggest blunders were 23. black pushing c5 pawn and 38. black knight to g6 (both of which FC was able to capitalize on)

Interestingly black was winning for the first 22 moves or so but it was by a pretty small amount. After that white was winning for the rest of the game.

FC's knight was trapped the whole game on g1 and the biggest blunder I found was 7. King f2 (which would have dropped the d4 pawn if black bishop g7 or close to it, and could have caused a pinned queen.). It was a pretty clean game honestly, blunders-wise.

Nice domain attempts by the Favour Chess AI, very bold. The King is a fighting piece after all anyways so there is no need to tweak the AI to not push the king when domain victory is disabled.

It would have very likely pushed domain to their promotion row in the two long games if it was still trying to do that.

ceo first game: king go brrrr...
