These are so much fun to solve!! Thx for sharing these fun puzzles.
Give A Stalemate #2-Zwickmühle
It's a nice stalemate scheme and the 30 moves look safe, but with dozens of different move orders it is not suitable as a puzzle challenge. You can probably eliminate some but to get rid of all of them would be an awesome achievement!
I said "unsuitable as a puzzle challenge" and I meant "on chess.com" because this puzzle interface can't handle puzzles with multiple solutions. With a bettter puzzle interface there may be better options!
please someone confirm if I'm right 3. Qg2 is a checkmate right?
You are absolutely right! But the assignment is explicitly to stalemate, not to checkmate! Composition chess is a Wild West of non-standard rules and non-standard goals. For instance there are already over 2000 registered rule sets and most of them combine with each other as well giving you millions of options. Compared to composition chess, your chess is as quiet as a mask-selling shop near the WH.
Here's the another stalemating problem. White stalemates Black in 30 moves. God luck!
