Re: Speaking of Blathy

Is there any hope for this one. 2...b5 seems to salvage the draw for black. Blathy's original idea was to use the king to go around the "stalemated" queen in the middle of the board.

Re: Interesting "exchange for bishop pair" position

Stockfish fought bravely but unfortunately had to admit defeat in the end. It looked like a fortress for a while but Leela found a way to break in. TC: 30m+45s | Game duration 2.5 hours.

Interesting "exchange for bishop pair" position

14. Rxe6 interesting but dubious per engines. Latest stockfish dev is capable of holding this as white against Ceres and Dragon. Haven't been able to test against Lc0 yet. r2q1rk1/1p2b1pp/2n1pn2/p7/2Pp4/P4NP1/1P1N1PBP/R1BQ2K1 w - - 0 15 [Event "Lozovatsky Memorial-A 2021"] [Site "https://lichess.org...

Of course we have the moremovers from Otto Blathy that is unreachable for engines.
What does "moremover" mean exactly?

Re: Drawkiller practically lost for black

Yes pohl. My intent was to highlight that the example position has the drawback of the c7 pawn.

In the games i have tested, white usually move the knight to b5 early on with the aid of the queen on tha a-file.

Drawkiller practically lost for black

The standard drawkiller opening setup is virtually lost for black. I have tested this position many times and in almost every game black is losing. The problem lies in the weak pawn on c7. If the King stand on b8 instead, that pawn can be defended and a vital tempo is not needed to used on that. Bla...
