It is hard to checkmate with 2 knights or bishops in endgame

No, I can't do it but I've seen it done by a GM lesson. It's not easy. Do we have an example on Chess.com?

Hello

- 2 Bishops is possible and I'd say about 1400-1600 range people tend to learn it

- B+N is possible, but I'd say most 1800+ learn it if they ever do and many titled players (including GMs) have occasionally failed this checkmate before. Often times because it's something they learned years ago and then forgot the winning technique of.

- 2 knights is NOT a possible checkmate to force. It can be forced in some very rare cases where the opponent has one pawn, but the winning method is not really a "theoretical endgame" I consider because it's a bit different each time and requires a lot of calculation if it's even possible to force a win from the given position at all.

Here's a YouTube short of me doing the chess.com B+N checkmate drill:

Actually, it is possible to force mate with two knights and a king if the opponent has a pawn on or behind the Troitsky Line. That is a4-b6-c5-d4-e4-f5-g6-h4 if Black is the one with the pawn and a5-b3-c4-d5-e5-f4-g3-h5 if White is the one with the pawn.

Use one knight to block the pawn (DO NOT CAPTURE IT) on or behind the Troitsky Line, use the other knight and king to shoulder the opposing king towards the corner, giving it 2 squares, like WKg6, WNd7, WNb5, BKg8, BPb6, then 1.Nd6 b5 2.Ne8 b4 3.Nef6+ Kh8 4.Ne5 b3 Nf7#.

Here, the pawn only got to b3, but in the worst scenario, he promotes and you mate him.

Without a pawn for the opponent on or behind the line, it is only a draw.

Yes @ThrillerFan I have seen the Troitsky line before and alluded to it in my comment, but perhaps it got buried in there so you didn't notice it:

I already know how to do 2 bishops + Bishop & Knight, didn't even really need to learn, they just came naturally with a little practice against Stockfish. 2 knights is the interesting one. It can't be forced despite checkmate positions existing, because of the fact that knights can't triangulate to time it right, will always result in stalemate first. 2 knights vs pawn (s) is possible because it allows the side with the knights to lose a move getting to the checkmate by avoiding stalemate. The most "basic" example:

Faced this just once, offered a draw instead. I have been trying out on Analysis Boards but the B+N is very hard. Will have a relook at your video and playlist. Thank you!
