After Qe2+ Qe7 isn't this the same thing again? Queens are coming off, resulting position is won for black...Jack Lad wrote:[d] 1n1qk1n1/8/8/8/8/8/7P/3QK3 w - - 0 1bob wrote:One interesting test is to remove the rooks, since this is a KNNKP type ending, and sure enough, it appears that if rooks are traded, this is a win for black because of the poor white h pawn location.
In this position if white simply trades queens then the position is lost. Better to play Qe2+ instead but can white hold on?
Draw?
