Bf6+, after the only legal move Kh7, then eventually trade the bishop for the knight? (Black’s bishop is useless since you can just move the rook and king to light squares, eventually forking the king and bishop with your rook. (Idk, the bishop’s continued existence would still deprive you of the zugswang required for a lone rook mate). Or, you could trade your bishop for the knight and then move your king into opposition using only the light squares to deprive black of any forced drawing positions
A rook vs bishop ending is usually a draw (with few exceptions). It’s not the solution here. For some hints, you can read some of my comments below.
Rf6+?
You mean Bf6+? That’s the correct first move. How do you continue after …Kh7?
Rf7 wins a piece, doesn’t it? After that it’s just a matter of technique, as they say.
Bf6+ Kh7 Rg7+ Kh6 Rf7 Kg6 Rf8
Would be the line I’m thinking
All good so far, but the line continues. Black still has a tricky defensive idea up its sleeve.
Yeah I’ve tried in a chess app with the AI difficulty set to max, the knight almost immediately ends up winning your rook and forcing a draw
No clue to be honest. I mean, you either move the Knight and loose the Bishop or the other way round. There are no immediate forks on the board and I see no stalemate tricks either.
You can of course play for Knight forks, but with the king being so far away from the pieces, that would be pushing it as a defensive resource.
After 4…Nc6 5. Bxd8 Black has a nifty intermediate move which is still losing but makes things a bit less simple.
Are you referring to Kg7 Re8 … ?
I mean anything other than Re8 is a one move blunder, so should be easy enough to see, but yeah, Rook vs Knight is unclear.
