Game 5 of the post: one of 600 games between AB-JChess-20261031 and jqe on 2026-10-31, 4 seconds a move on 4 threads. jqe has Red. The game is drawn; the board faces Black, whose chances AB-JChess read first at the marked move. The graph is both engines' chance for Black, AB-JChe…

jqe, with Red, moves the chariot from f3 to d3 here; AB-JChess would move the other chariot from a10 to f10 and trade chariots at once. The game follows jqe’s line move for move from here.

Red’s chariot takes a face-down piece on a7. Since the split Red has taken a horse and traded chariots, as jqe’s line planned; our reading is that jqe counted the material and AB-JChess the attack Red gave up for it.

Red turns over the piece on d1, a soldier, and AB-JChess now has Black well ahead.

From here Red’s chariot goes back and forth between f7 and f4, and Black’s elephant between c4 and e6.

Drawn: the same position came up a third time. AB-JChess had Black winning, but it was sent each position on its own and could not see the repetition coming.
