RE: Nice (surprise) mates, a contest and a fun tournament at the usual time!

Nice to have freestyle chess while there is Grenke freestyle chess tournament
rook checkmate looks good

I checked some starred games and choose some knight checkmates - older games but they look nice

First one is this double knight check after Queen f5 blunder
All knights together

b6 was played move before
