It’s been a while since I gave you a problem to solve. This is a helpmate in 2, composed by Andy Kalotay (USA) and first published in the November 2019 issue of The Problemist supplement.
In a helpmate in 2, Black plays the first move and both sides work together to produce a checkmate on White’s second move. There are two solutions.
It’s not so hard so do have a go and let me know if you find both solutions.
