simple puzzle but very nice.:)

Got it first time. Thanks for shring.

Henry(Stavisky), I have thought about that move and my calculations predicts that I would get his queen but high probability of complication.... a push pawn to h6 is an initial setting up of trap knowing that he will have material advantage, giving  a rook check forces the trading of his rook for a rook and a knight. letting him capture the knight would remove the bishops protection of h7 square making the realization of my set-up trap of forced 4 move mate with 3 different forced mate variation that is impossible to repel. I also posted the 2 other forced mate variation for reference. Try to check-out the 2 other lines of mate combinations in posted in comment further down the post.

Sometimes capturing major pieces is not necessary to deliver a mating combination. If there's an option to simplify things.... one must grab the opportunity for a short mate than complicating the game with trying to gain material advantage unnecessarily.

 

Hallo Mike, I just had time to look the very first game: I think you could have won this game with: 30 )Rg1 and he lost his Queen !

well played,i figured out first time,:) nice win

other line of forced mate...

 

nice game i didnt get the first move but when i saw that i figured out the rest!
