The solution to last Monday’s problem is that White does best to play 1. Qf3!
If Black swaps queens, the ending is easier for White to win. In the game, White won after 1… Qc1+ 2. Qf1 Qe3+ 3. Bf2 Qxa3 4. Bd4 with a winning attack.
In this week’s problem, White is a piece up, but he is faced with a vicious attack.
What is the best way for White to defend?
