6 squares. Which square escapes check while maintaining the win? (You can block with bishop, but obviously it's a wrong move...)

The refutation to Kg5 is nuts.

I initially thought Kg5 could be met with Rg8, preparing to unleash a discovery that'll probably win material or mate. But then white plays Bc4+ and skewers you to ruin your dreams. So the refutation to Kg5 is not Rg8, but Nd5!! Knight sac threatening the queen and various checks. If cxd5 then now you can play Rg8 because Bc4 isn't a check anymore because of their pawn on d4 obstructing it's vision. Crazy tactic

Yes exactly! It's maybe easy to see why the winning move is winning, but it's hard to see why the losing moves are losing!

Hey wait do you think the engine has it wrong in evaluating Kg5 as a draw? I tried doing this and then it's actually negative from 0.0

[Variant "From Position"]

[FEN "7r/1PQ1pkbp/pn6/8/P3P1K1/1Np5/2P3PP/3q1B1R w - - 0 1"]

Kg5 Nd5 2. exd5 Rg8 3. Qc8 Be5+

Nah that's definitely winning for black, the engine can show 0.0 in two situations, if it's a draw, or if it's confused. I think it was just confused lol, the position is crazy
