Daily Chess Puzzles

[Jannes]

Men my working memory is shit. I remember I could imagine some frequenes in my head back in the day, now its hard to imagine just a few steps if I dont see it directly in front of me. Its like I lost half my eyesight. Wtf happened to my brain..

Will try puzzles under different circumstances, with adhd medication, with body doubling and see if it has any effect.

Black pressures check mate in 1 so white can only get out of the situation with continuely giving checks each turn.

Rook to a8 forces King g7. Rook g8 forces King h6. Check Mate in 1 is prevented. Does the puzzle continue?

Yes the puzzle continues, white to move and win. Final possition must be a clear win for white.

Black pressures check mate in 1 so white can only get out of the situation with continuely giving checks each turn.

Rook to a8 forces King g7. Rook g8 forces King h6. Check Mate in 1 is prevented. 

...

Bichop to d1 blocks the Kings way out and pressures check mate in 2 with Rook to g6 the following turn. To prevent this black can only stall with moving the black pawn to g4, but that can be taken out with the Bishop. Black can also attempt to trade Rooks with Rook to g7 but that seals the fate as it blocks the kings way out for the finisher Rook to h8.

Have I missed something?

White to move and win. White pawns move up.

Rook a8 check -> a7 check -> take black rook w/ check -> black king recaptures on h7 -> push e5 pawn. Black can't catch it before promotion.

I don't see a clean win here. White rook needs to go to A8, then G8, then things get messy but white should win by pushing pawns.

What? Rook can't go to g6, king would just eat it.

King would not recapture on h7. Instead black captures white bishop with his other rook.

This one's more hairy than it looks.
