Game 3: AB-JChess vs jqe

AB-JChess vs jqe: 5 games read by both engines

143 moves

Game 3 of the post: one of 600 games between AB-JChess-20261031 and jqe on 2026-10-31, 4 seconds a move on 4 threads. AB-JChess has Red. The board faces the winner, AB-JChess (Red). The graph is both engines' chance for Red, AB-JChess teal and jqe orange. Wherever the two engines…

Black’s soldier takes a face-down piece on b3, and both engines put Black well ahead.

Red’s cannon takes a face-down piece on g7, and both engines now have Red ahead.

jqe, with Black, moves the cannon from e4 to e6 here, starting a run of trades. AB-JChess would move the horse from d6 to f5: in its line Red’s horse takes the cannon on e4, an elephant takes it back, and Black’s horse goes on to take an elephant on h6.

The game has followed jqe’s line move for move: Black has taken an elephant and an advisor and given a soldier and its horse. jqe scored this line about the same as the horse move; AB-JChess scored it clearly worse for Black.

This is the third move in a row to turn a piece over, and here the two engines’ numbers meet: part of what jqe caught up on came from reveals both read the same way.

Black has no legal move: Red wins.
