Have you ever had to checkmate with 2 bishops or bishop and knight in an actual game?

I have had pawns before while checkmating with 2 bishops. I had pawns blocking the kings path while I checkmate with 2 bishops, but never an actual 2 bishops checkmate or that I can remember of.

In my case, never.

i had it and is not nice

bishop and knight is a nightmare to mate with

I've had the losing side of a bishop and knight ending once on chess.com. luckily, my opponent didn't know the technique and we drew.

Yes, I've had both several times in actual games. 2 Bishops Checkmate is more common though. Here is my most recent N + B checkmate from a game though. Cool thing is that it was converted in a blitz game   Endgame begins around move 60 where I had less than 3 min. 30 sec on my clock.

p.s. Diagram fixed, since it didn't format properly when I originally posted. Also, don't critique the game too much. The focus is the cool endgame; the early part of the game was definitely tilt from my previous blitz loses in the day and me trying to get back rating xD

How did you manage to pull that off! I have had it once and it took millions of goes to get into the ideal position to checkmate.

The only time I gave a simultaneous exhibition (during a holiday in Austria, against 20 locals), one of the games went to KBN versus K. Fortunately I remembered the strategy and managed to mate within 50 moves. In regular board play, never.

 I studied that endgame before and I also played chess a lot. Just for B + N, I recall at least 4 games I got it. One was OTB casual game with a friend where I converted the winning side, two games were chess.com where I converted (but only this was won in blitz; the other a longer time control) and the other game I failed to convert because I drew on time. I had like a minute and a half on my clock (that one was a 3 min blitz game I think). 

I don't remember if I ever got the defending side of a B + N ending, but I don't think so. 2 Bishops checkmate is more common, but both are rare.

Wow, gonna go have as look at it now. Now that I think about it, I realise that is serious flaw in my chess skills.

Not that I can recall.

It's never happened to me in a single game In my life. So I have no interest in studying it, I prefer studying positions that do occur in my games. 

It can't be a serious flaw. It simply doesn't occur nearly enough for it to be that relevant. Usually when someone is down 2 pieces they will just resign or usually you will have a pawn that you can promote or something. 

It is more that I rely too much on the opening and middle than working on an ending.

True, but even though the B + N checkmate doesn't come up much; the confidence that you can convert it helps. You don't want to be approaching the endgame while also worried about trading down with too many stipulations. Knowing that it is coming down to B + N (even though unlikely) helps if you are still confident the game won't be drawn. 

Also, even though rare in games, the learning process of B + N does nicely teach piece coordination and corralling the enemy King. Other endgames teach the similar motifs, but this one is especially delicate with it. Even GMs have occasionally failed to convert or had time get them a draw. I'd say 1600-1800 chess.com rating is about the range when you could perhaps consider studying B + N checkmate. By all means you can research it before then, but the endgame is tricky enough to give some frustration if you don't have an idea of how to make progress.

I do agree that there is some value in it. I think I can do the 2 bishops one, the knight and bishop is somewhat harder even though I have watched some lessons on it, I doubt I could do it in a 10min game when in the endgame I'd have 2-3mins probably.
