Batavia GM Amsterdam 2014.3.1 Position after 27 moves of play. The unusual location of the Black King gives an excellent indication of who stands better, and why. BUT, having a won game and actually winning it are two different things…and against a highly resourceful player like Williams one can never expect the position to win itself!
HERE Black is threatening 28…QxR. Wrong would now be 28.R(5) xd5?? as , once more, 28…QxR! exploits the weak back-rank.
WHITE TO PLAY AND WIN!
