This is a tricky checkmate to learn and even once you learn it, still hard to replicate in a real game situation. Which part of the checkmate do you struggle with? Is it the W-maneuver itself? Some variation? Or is it forcing the King towards one of the corners of the chess board to setup the W-maneuver?

It’s usually getting the king on to the an edge without allowing draw or delaying the game. I’m usually able to deliver checkmate once the kings on a wall

Yeah, getting the King to the edge is the toughest part I think for me too.
I know this checkmate really well (even done it successfully in blitz before ), but I've also practiced it a lot and there isn't really an exact method I know of (other than Deletang's Triangles, or whatever it is named, but I don't find this practical as it just complicates things unnecessarily for me).
Off the top of my head, I most have three tips for forcing the enemy King to the edge of the chess board.
1) When given the chance, try to lead with your King as it does the best at keeping the enemy King restricted.
2) Try to get your King with the Bishop directly in front of it, or next to it; this blocks a lot of squares and helps push them back.
3) It is sometimes useful to try and wall in their King by placing your Knight and Bishop on the same color-complex. This is because the Bishop is stuck on it's color, but the Knight isn't restricted to light or dark squares, so having the Knight on the same color square as your Bishop means the Knight will be controlling the color complex the Bishop can't reach. Together, they coordinate and help take away squares for the enemy King.
I don't really know of an exact method for finding specifics. It is more of a learn and practice type of endgame and it becomes easier to do with experience. Hope these bits of advice helps

Yea I think I’m getting better at preventing a slippery kings when I got all the time in the world but Imma need some more practice doing it with a timer especially when rotating the knight or bishop

Yeah this is a tough endgame and even titled players sometimes fail to convert this checkmate due to time pressure, or because they learned this checkmate years ago and since forgot the correct technique.
Once you get the main ideas down, then it just becomes a matter of practicing it a lot and getting better at identifying the W-maneuver when rotated. One visual trick that can help you do that is to mentally draw the W path backwards. Identify the checkmating square you are aiming for (same colored corner as your Bishop) and then note the square diagonally over from this. That is the square your Knight will get to before the final checkmating portion. Then mentally draw the W backwards from there and you'll find your starting Knight square 3 files/ranks from the other side of the board if that makes sense.

Actually drawling it backwards is kinda genius, Thanks for the help!
I tried a similar thing myself trying to mirror it in my mind and drawing it out, but this was difficult for me to do. I got the idea from drawing the W backwards from an old video by GM Daniel "Danya" Naroditsky


Nice checkmate. I've also successfully converted B+N checkmate in real games before, but I've never actually sacrificed everything else to reach this endgame like you did. The several times I've gotten this checkmate, it was in a real game where we didn't pass on a checkmate we saw.
Still nice game for you though and good practice to illustrate that you can get this checkmate in a game of your own

Yea People resign to often I just wanted to do the mate at least once
The one thing that does still get me is the fact that when I’m about to mate and I need to take out the last opposite square with my knight I need to do it with check or it’s a draw and so I need to have get to their but the number of knight jumps must be odd if the king is already on an opposite square than my bishop and even if it’s the same square.
currently I just jump the knight around forever till I finally get it their on the right move, so I’m not sure if this has a dedicated method or if it’s just practice but it was a bit scary at the end.
So I was practicing my formula for bishop, knight mate and I got it pretty good and beat quite a few bots with it, but how do I do it with maximum efficiency because I keep getting 50 move drawed
