In one of my recent games, the player of the White pieces neglected the safety of his King.
In the diagrammed position, White has weakened the white squares around his King and he has played f3 in response to Qb7+, opening up the second rank.
This allowed me to launch an attack against his King. What did I play? There is more than one good move, but one move in particular is very troublesome for White.
The solution to last Monday’s problem is that White sacrifices two Queens in one move by playing c8=Q. He can then win by putting one of his Queens on the seventh rank.
