You mean Bf6+? That's the correct first move. How do you continue after ...Kh7?

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago (1 children)

Rf7 wins a piece, doesn't it? After that it's just a matter of technique, as they say.

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago* (last edited 1 year ago) (1 children)

Bf6+ Kh7 Rg7+ Kh6 Rf7 Kg6 Rf8

Would be the line I'm thinking

[โ€“] Bonifratz@feddit.de 1 points 1 year ago (2 children)

All good so far, but the line continues. Black still has a tricky defensive idea up its sleeve.

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago (2 children)

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.

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago

So you end up with Rook and Bishop vs Knight or Rook and Bishop vs Bishop, both of which should be winning. I can of course imagine myself drawing those by screwing up the 50 moves, but that's about it.

[โ€“] Bonifratz@feddit.de 1 points 1 year ago (1 children)

After 4...Nc6 5. Bxd8 Black has a nifty intermediate move which is still losing but makes things a bit less simple.

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago (1 children)

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.

[โ€“] Bonifratz@feddit.de 1 points 1 year ago (1 children)

So 5. Bxd8 Kg7 6. Re8 what do you play after ...Kf7? By the way R vs K is a technical draw (so not the solution here, even if difficult to defend for Black).

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago (1 children)

Rook vs Knight is a draw, but Kf7 Rh8 Kg7 Bf6+ Kxf6 Rh6 picks up the Knight if you want to go for that trick

[โ€“] Bonifratz@feddit.de 2 points 1 year ago (2 children)

Perfect, you found the entire solution!

[โ€“] ck_@discuss.tchncs.de 1 points 1 year ago (1 children)

Full disclaimer, I did have to put it on the (analog) board in the end to find Bf6+ ๐Ÿ˜“

[โ€“] Bonifratz@feddit.de 1 points 1 year ago

Nothing wrong with that. :)

[โ€“] Epicurus0319@lemmy.world 1 points 1 year ago

Yeah Iโ€™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

[โ€“] shoelace@lemmy.world 1 points 1 year ago* (last edited 1 year ago) (1 children)

I'm no good at endgames bit but I assume it's...

Bf6 Kh7 Rg7 Kh6 (Kh8 loses to a discovered check) Then the knight is pinned and the black king is stuck on the H file, so the white king can move up and trade down to K R vs. K? You'd just have to make sure you don't get forked by a knight check when moving up.

But that seems too simple so I'm probably missing something.

[โ€“] Bonifratz@feddit.de 1 points 1 year ago

The problem is that the knight can unpin itself, giving White no time to move the king up like that.
