But as I pointed out in my link, the lone king navigating to the wrong corner is a bad idea in practical play, because every man and his dog knows how to mate him from there. The losing side should not play accurately all the time if he wants to draw.

In practical play or not, this is the only chance to last long enough to get a draw by the 50 moves rule. Already, out of any position, the attacking side will win in 25-30 moves with accurate play. One just cannot force the attacker to misplay, and giving them the chance to win even faster is no good idea at all.

And no, not "everyone and his dog" knows how to push a King along the edge from one corner to an other, it takes some practice and a few nifty zugzwang moves. I have seen a 2100+ fail to win that very endgame in an official classical tournament, so, you and your what 600-700 Elo level and experience may remain humble instead contradicting so a much stronger player. "Should not play accurately" is ridiculous a sentence and false an idea.

Well, we can try a few positions out if you like. I suggest I take five random KBNK positions with mate lengths >= 18 from Wilhelm, and play them either side and we score the difference in game lengths (or draws if any, but there probably won't be). I'll message you the positions.

Basic endgames have nothing to do with playing strength.

"Should not play accurately" is far from ridiculous. There are no extra points for losing accurately.

Thought that might be your response.

There are lots of YouTube Videos explaining how to checkmate with knight and bishop, although I don't think it's a necessary skill for most players.

Happy Learning btw

Checkmating with a knight and bishop requires precision and patience. First, use your king and pieces to force the opponent's king to a corner matching your bishop's color. Next, create a "wall" with your king and bishop for today egg rate, gradually pushing the enemy king to the edge. Then, maneuver your knight to control key squares, limiting the opponent's moves. Finally, coordinate your pieces to trap the king, with the bishop controlling the long diagonal and the knight delivering the final blow.

Or, you can simply sit down on a Sunday afternoon with a cup of coffee and figure it out. It's really not that difficult.

To checkmate with a knight and bishop, use the knight to control the escape squares while the bishop passes the check. You can orchestrate this by pushing your opponent to the edge of the board, using the bishop to control the diagonals, and using the knight to cover key squares, gradually pushing the king back.

A checkmate with a bishop and knight puzzle

Why black made those moves? because I tried it with stockfish and it almostly always plays those moves

These endings don't work very well as puzzles because there are too many equally good alternatives. You can do better on move 7 - I'll leave you to work out how.

If you're practising the endgame, SF is not generally a good opponent unless you've installed the tablebase because it's accuracy is really bad. You may have installed it, because it looks ok there, but that could also be because it's a short mate.

Here is me trying a mate in 31 against SF15.1 without TB some time ago. It collapses in 23 moves.

Checkmating with a knight and bishop is a challenging but achievable endgame maneuver that requires precise coordination between the two pieces. The key is to drive the opposing king into a corner that matches the color of your bishop.

I'm trying to learn it now though

At worst, you should have drawn.

Some pretty strong grandmasters have drawn games because they couldn't do the checkmate. Takes special talent to lose.

He must have overstepped a time control. The game he showed was drawn.

It's good to practice it as a form of mental sharpening but, quite frankly, it comes up so rarely, you would be better spend your time on Rook and pawn endings. I do provide the information to the kids I teach as part of showing them basic checkmates but I do stress, for practical reasons, K+Q, K+R and even show how 2 Rooks can do it without the King's help.

Drawn by a 50 move rule claim (or more likely chess.com's interpretation of the 50 move rule).

But he shouldn't lose by overstepping the time control anyway because his opponent would have a hard time mating with a lone king.

I hope you also mention that in many positions they can do do it significantly faster with the king's help.

NGL but this is not easy to learn and implement. I've practiced it quite often and now I'm able to do it in like 35-40 moves... Now I'm not practicing it that often because this endgame rarely occurs. Any tips for me?
