In this week’s problem, Black is winning.
However, care must be taken at all times or else accidents can happen.
An accident can easily happen in queen versus rook endings.
Black carelessly played 1…Kf2. How did White respond?
The solution to last Monday’s problem is that White plays 1. h4!! c1=Q 2. Qg5+ Qxg5+ 3. hxg5 which is a double check, allowing White to play Rook takes Queen on the next move.
