Re: KnightX 3.3 engine released
Just finished a LTC match versus Zarkov. Ten games played at 180 seconds a move, using Noomen's Short Lines Opening Book. The match was played using HCE Pro GUI and ended in a draw. (2+ 2- 6=).
Here was an instructive Rook and Pawn endgame that KnightX went on to win as black.
Fen: 8/5R2/1k6/5p1p/6pP/3KP2r/8/8 w - - 12 85
Here Zarkov played the move Rf6+??

Re: KnightX 3.3 engine released
Zarkov is a good engine.
I have analysed this position with Knightx 3.3. Rxf5 is the best at almost every time but I see that sometimes Rf6+ is considered better in a null window search (fail high move). The following search with a wider window does not consider this move to be better and it is skipped.
Zarkov may have been in a similar case.
