Figure these out!
SPRAGGETT ON CHESS
In the position below, Black seems to have everything under control, despite being an exchange down. If White takes twice on c7 then the Black King is stalemated. And if White takes only once on c7 and then slides his King over to defend his Rook, Black captures the b-pawn with his Knight and the draw is airtight.
What had Black missed?
WHITE TO PLAY AND WIN. HOW?SPRAGGETT ON CHESS
The next position occurred in the game between Ivanisevic and Jovanovic, in the 2009 Serbian Team Championship. White has sacrificed a piece for the attack. Black reasoned that if White now tried to exploit the pins with Nxf6ch, the King slides over to d8 and Black is quite safe.
Instead, Ivanisevic made a move that Black completely overlooked, and Black resigned immediately! What move did White play?
