Hi!
Today Hossa played a blitz game with Tinker at ICC where a KBPKP endgame was on
the board:
[D]8/8/p4b1P/3K4/8/8/8/1k6 b
Hossa evaluates this as a win for black, because the black pawn has a black
promotion square and there is no white pawn on the b file in front of the black
pawn. Unfortunately this position is a draw. Can you define a rule for such a
position class ("search will do it" doesn't count; at least the big score I gave
for this position costed 1/2 point in that game)? I think it should be a
combination of this:
1. white has an advanced white passer
2. the black king isnt able to protect the black pawn
3. the distance between the pawns is big
Greetings,
Steffen.
