A. Karklins - Pelts, Oak Brook, 1990
Black to play and win
FIDE Master Peter Pelts hasn't played much since the mid-1990's. He was in good form at the 1990 Illinois Open, when he beat the formidable Andrew Karklins in a nifty pawn ending.
Can you find Black's only winning move?
And is it better to have an outside passed pawn or protected passed pawn? (The correct answer, as always, is "Depends on the position.")
