The answer is for black to play K-b6. White has a choice to make a useless move with his queen or postpone checkmate for a while with K-c8. However, playing K-c8 drops the queen when black plays R-h8 and it’s an easy win from there.
I hope you found the answer. Look for another new chess puzzle in my next post!
Chess puzzles seem to come seldom. Can you do this on a regular basis? I like it.
