A Queen and Knight can cooperate very well in the endgame.
In this week’s problem, White can force a win with a clever sequence of moves. He has an advanced pawn on h6, which means he may be able to sacrifice something on g6, if he can then play h7 and queen his pawn.
How does White win?
The solution to last Monday’s problem is that White can check Black in 7 moves by playing Ra1,Ra5,Rh5,Rh7,Rd7,Rd8 and finally Re8 check.
