The solution to last Monday’s problem is that White plays 1. c5! to get a large advantage.
The Black Knight on a4 then has few squares, and the White Bishop on f1 can move to a6, helping White to take control of the b-file by stopping Black putting his Rooks on the b-file.
In this week’s problem, White is again faced with the task of making his two bishops count.
One clue is that the Black knight on d5 is very strong. It needs to be undermined.
How does White weaken the Black position?
