If the Bishop trades itself for Knight, White will win by promoting the pawn.
If the Bishop trades itself for Pawn, White will win by doing Bishop + Knight mate.
Black was lost either way.
The best option Black would have is to take the pawn and hope you don’t know how to mate with just Bishop + Knight.

Yes I understood this, I don't know how to mate with bishop and knight...
My question is - theoretically is it possible to force promotion, or altervatively, can Black force the bishop sacrifice (for the pawn)?
To Checkmate your opponent with Knight + Bishop
You have to checkmate them in the same corner as your Bishop Color.
If it is Light Bishop, than you checkmate in Light corner.
If your opponent is smart, they would run to Dark corner. Than you have to herd them to Light corner by force using the “W” technique with your Knight.
The tricky part is the Bishop waiting moves.
Be very patient so they move on right square.
Don't forget to do waiting moves with Bishop when necessary.
There you have it my friend!
You now have knowledge to win with Bishop + Knight!
Mwwwhahhahahahaahahha
Now you can see clearly your opponent resistance was futile! Hopeless their position was!
N+B is completely winning
I just looked at the final position and a few moves leading up to it (I didn't check with an engine), but it looks lost for black. If I was black, I'd probably give myself practical chances for a draw by 67...Ke8 and keeping my bishop eying the c8 promotion square. If I ever get the chance, I'll sacrifice the bishop for the pawn and make them prove they know B+N checkmate.
Even titled players have failed this checkmate before. Of course, it is a theoretical checkmate which titled players should know, but it rarely comes up in real games and in the case of titled players, this checkmate is one they typically learn early on and then haven't seen in many years and forgot the details of it.
Most titled players will probably convert B+N successfully, but players under 1800-ish level will probably struggle to convert this in a real game, unless they've studied this before.
For entertainment, here is a short where I clearly know this checkmate well: https://www.youtube.com/shorts/v_ox8Ea0aqE
but here is a more instructional video of mine on how to do this checkmate:
Much more common are endgames such as a single pawn winning via king opposition. These are foundational to know:
Knight and Bishop is indeed a hard mate to do.
Yes, Danya is good. That was actually one of the videos I watched when researching for my B+N checkmate video, but I first learned this checkmate from the YouTube channel chessexplained many years ago (they aren't active on that channel anymore).

"avoid playing the bishop & knight vs King because I can't really do that"
++ You should learn how to do that.
'The student will do well to exercise himself methodically in this ending, as it gives a very good idea of the actual power of the pieces, and it requires foresight in order to accomplish the mate within the fifty moves which are granted by the rules. ' - Capablanca
Thx all I will definitely study it .
but my question is still unanswered
ill clarify
around move 45. Let’s say I want to avoid the B+N mate, can I force promotion ?
Or alternatively can he force the B+N mate eventually?
thx
(the engine is useless for studying this cuz for him it’s ALL +49)

sorry but looking at the table base dosent help me understand. the table base fastest mate is to just give up the pawn and preform N+B... I was wondering if there is some endgame technique to avoid that and force promotion and the bishop cant recapture maybe something like this 
for lazy people)
but i couldn't reach this position, or find a plan to make this happen... I was wondering if this is due to some infamiliarity with endgame patterns

You was never in a position to force promotion of pawn.
Look at move 41 in your game.
41…Bxh4 - Everything will trade down at that point and you will have N + B.
You couldn’t really force it.
———————
However, if we ignore all moves before move 45, you might of had something at move 47.
I don’t know if you can force the pawn promotion.
It might require some help from your opponent, but it does look like something could be their.
If you look at move 47, Black bishop is very far away so you could play c6 and even c7.
Also, you could move your Dark Bishop to f2 to h4.
Your knight on d6 + Bishop on h4 would create a wall which wouldn’t let your opponent King come closer to your pawn. This could give you time to wiggle your King around closer to the pawn. Than you can move your Knight around to block.
It’s an interesting idea, but will it work?
Not very sure to be honest.
It will probably be impossible for black to sac their bishop as after white plays c7 and black ke8, white could play Bf6 and zone the king away from the pawn, and the king and knight let the pawn promote.
"I don't think I can actually preform the B+N Mate."
Actually nobody in the world knows how to preform it.
But in case you want to perform such a mate, it's not difficult, and there are a few "easy" methods which you can use and mate the opponent even blindfolded. My preference is the Deletang method (Google it) because it uses a very simple concept, but you may like some other one.
Can you avoid it? Likely not, but in any case, why should you avoid an ending which is winning without much trouble?

My plan was to do the bishop knight mate but wait to begin it a few more moves, see if I can sneak the pawn through. I thought if I inevitably will reach the position might as well tire the opponent a bit more... and he blundered... but I was intimidated because I've failed this mate before
Even as late as move 65, it’s not totally obvious how you would avoid needing the B + N mate if he simply plays …Ba8 and then waits with either…Bb7 or even …Bg2/…Bh1 at any juncture when you’re not able to shut the B out with Nd5.
That said you’d be getting a favourable starting position for the B and N mate with his king already on the edge, so some of the work is already done.

Ah! Thank you bro..
So you're saying basically with perfect play he could wait with Ba8-Bb7 and there is no way to avoid the B+N ending after he sacs?... (For example, reaching a position like what I was aiming comment #13, is impossible?)
Wrong coloured bishop applies to rook pawns. I think you did well to tack about a bit seeing if would blunder if not confident of B+N win. You were right about 40c4 being dubious, b4 avoiding reducing the pawn population would have won easily. Some of the other annotations were mysterious presumably from software?
1. With perfect play, could I have theoretically have executed my plan, or did Black have a possibility to absolutely force the Bishop+Knight vs. King position?
2. Could he have gone for taking the Knight and going for the "Wrong Color bishop" draw?
Thx
