I love this endgame and I've gotten this ending 3 times I can recall (none from the defending side) and I've converted all three into a win: two of them in blitz 
I know at least one of those blitz games was on chess.com, but I can't search for the game now because I'm not on my PC (I'm on vacation right now). No promises, but I might search for the game(s) in about two weeks from now when I get back home.
p.s. I'd like to see this endgame from others too
I've been trying to learn this mate for some time (with various degrees of success). I've read that it only pops up in something like 1 out of 6,000 games. I've been playing chess for 30+ years and have never encountered it. I'm curious if any other players here have experienced this endgame on chess.com, and if so, would like to post their games, win or lose? I read that, a few years back, even the female world champion was forced into a draw due to the 50 rule move because she couldn't do it. Would love to see some real examples, win or lose, to study. Thanks.
I only come across this in endgame puzzles and never in a real game before (even though I had opportunities to intentionally promote a pawn).
I got it a couple of times OTB and a couple or more here, any meaningful statistic would have to account for those that resign before it appears in its pure form. I remember Grischuk down to his last seconds making 20 instant moves and mating someone OTB recently.
I had it one time in daily with the lone King. My opponent won in about 40 moves after a couple of mis-steps.
I like the drills too but the problem with them here is they always start in the same position. Would be nice to see random positions and sides.
Since you'd obviously set your heart on a bishop and knight endgame, a tip would be to start playing it before you actually reach it. So:

See my post #4 here https://www.chess.com/forum/view/endgames/two-knights-vs-pawn-advanced (ignoring the first couple of paragraphs). That will give you what you ask for.
Most useful is to sit down on a Sunday afternoon and make a determined attempt to find a general mating method. This will be useful even if you fail to actually find a complete method. You will at least then find it easy to understand what is happening in the games.
The problem with the games, by the way, is that what is happening is quite often not what you want to learn.

This video shows a system that is extremely easy to understand and can be reproduced from any starting position! Although it doesn’t include some sidelines it’s a great start.
Watch this video and then practice the drill on Chess.com. If you find yourself in a position where you don’t know what to do next, just go back to the video.
Also lichess has three drills on this endgame.
What, in the middle of a tournament?

No while doing the drill.
I have played chess for over fifty years, and have only encountered this ending once, in an off-hand game. I had bishop, knight, and pawn against a rook, and when the pawn got near promotion my opponent sensibly gave up his rook for the pawn. Though neither player had been keeping score, he jocularly cited the fifty-move rule and started making hash-marks on a napkin; I knew the method, and mate was delivered in about 25 moves from where we started when his rook had given its all in devotion to the defensive cause.
Obviously it would hardly be worth studying the ending for its practical value in delivering checkmate in actual play, considering how seldom it comes up. Nevertheless I believe looking at examples, and practicing on a chessboard by one's self or with a friend, is worth doing early in one's development as a player because it fosters understanding of the cooperation of pieces.
Actually, it's not that difficult if one focuses on understanding the method in stages (confine the king to the edge of the board, drive the king to one of the two proper corners [where the corner square is the same color the bishop travels on]), and deliver checkmate there while avoiding stalemate), rather than trying to memorize a long series of moves. As in so many things in chess, understanding is more productive than rote memorization.
This ending does not require deep study of a sequence of moves, just an idea that you should push the lone king towards a corner square which is the same colour as your bishop, using your 3 pieces to deprive it of escape routes from this path.

When I was at a university chess club, I had an eccentric teacher who once said, if you can't handle a simple knight and a bishop in an endgame, how can you handle them in the far more complicated mid-game or opening? Also, wasn't there a woman world champion who drew her championship match because she couldn't do it in 50 moves. Must have been embarrassing.
