One passed pawn in the endgame can be stronger than two passed pawns.
In this week’s problem, White has a very good passed pawn on the 6th rank. The Black King is also trapped in the corner. White can use these two advantages to win the game, despite being material down.
How does White to move win the game?
The solution to last Monday’s problem is that White plays 1 Qxd6 cxd6 2 b4 Kf8 3 b5 Ke8 4 b6 Kd8 5 a6 and wins.
