End game drawn
Torben i would very much appreciate your view on this game i just finished.
we ended up with his R vs my 2 B. I have never encountered this ending before and was somewhat at a loss. He offered a draw and i accepted.
Question is was i right or could I have won?
below is the final position when a draw was agreed



The rest of the club can join in the discussion as well.
We may all learn something from the master

I wasn't aware
we don't get notifications if a new forum topic is posted - no that is something worthy of improvement. Sorry Pete, I only got aware of your question after you mentioned it in our game chat.

Without having analysed long lines yet, it is my impression that the draw is justified. Of course the bishop pair is a powerful advantage over one rook, but your position lacks stability. The term stability was anknown to me until I came across it in Mihail Marin's excellent books. He doesn't give a clear definition what it means, but from the context I concluded it means a position is stable when you have safe posts for your pieces from where they can coordinate and protect each other.
In our actual example the problem is the h-pawn: it should be defended by the dsb who in turn doesn't find a safe square from where to perform this task, as your only winning plan can consist of advancing with king and lsb on the g6 pawn - possibly shielded by the dsb as well, who seems to suffer from a work overload in this case. It is interesting to observe that the position would have a completely different character if your g-pawn was still on g3: in that case your dsb would have the perfect outpost f4, where it is both safe and helps protect both pawns.
So the only doubt which would need to be sorted out by concrete analysis is the question whether you can afford to lose your h-pawn while advancing into Black's camp with all your forces, but I'd be surprised if this was the case. Still I will give it a closer look when I find the time - I suppose the starting move for this lines should be Ke4.
