Puzzle of the week (#45/2026): from Bad Wiessee tournament, which ended poorly for me, but still some interesting moments. White refrained from playing tempting 1.Qd2-e3, which looks scary for Black. Can you see, why it doesn't work?

Solution: Sacrifice the rook! 1.Rc8 and after Rxc8 2.Qe5 no more Bc8+; otherwise Qb4 and always keeping e1 square under control

where 3....0-0 4.Rg1# seals the deal

and after 1.....Na7 2.Qc6 dxc6 the key move for White is to castle! 3.0-0-0!

(Puzzle of the week #40/2026) : We stay with castling theme. White to mate in 4 moves, good luck!

Solution: Because Black can castle, bK and Rh8 couldnt move. So the last move had to be g7-g5. So the solution is 1.hxg6 e.p. (P.S.) If Black couldnt castle then 1.Ke6 is the way

Yh, i was trying to check it, appearantly it's not obvious how to treat it
