Endgame study: Bishop and Knight vs Rook and pawn

#2
Remember: without other heavy pieces the rook is mostly no worse than two minor pieces in the endgame. So RR vs. RBN is much better for the minor pieces because they have a "coordinator". This is a common issue where inexperienced players struggle, they go for the two pieces alone and even lose.
#3
The theory says that BN is somewhat better than Rp. Practice is different. I managed to win BN vs R and 6 pawns for each size, but the case shown above is quite hard.
#4
I never had problems with two pieces vs rook in my real games. In that position however black has a pawn majority and that makes things harder for white. It's a difficult position to play but at least equal. I would focus on drawing as white.
#6
As I mentioned before if both sides had an additional rook it would be an easy win probably because white has an coordinator then. That"s the text book case normally: two pieces are stronger than a rook in the middlegame. The two pieces alone in the endgames are hard to coordinate against flank attacks, passed pawns and so on: the rook is equal in most cases.

There's a beautiful "classic" example played by Dolmatov in the endgame manual analyzed over many pages by Dvoretzky where he even succeeds with the rook and one could think the pieces where better. Pawns are even equal at certain times but you cannot simply add the material values given for beginners for the two pieces vs. rook:

#6 and why was that game a resign? Looks like a draw for me...

And thanks for the interesting idea to have 1 more rook as "coordinator" - never thought about that!

My example of B+N vs R endgame (though R side did not play perfectly):

First position white looks OK for me.Black has an extra q-side pawn but there is no progress to promote it.

There are a few guidelines:
1. Keep control
2. Activate and centralize your king
3. Try not to trade pawns
4. Keep the rook from getting active
5. Probe the opponent's pawn structure to create weaknesses

I'm giving up, for me it's a draw.
