I want to thiank everyone who has contributed input to this thread, and now I want to show the game that led me to start this topic.

Game 1420819

Let me assure you that I was not asking for advice when I posed the question; I had already exchanged my Queen for the two minor pieces. I just wanted a consensus of what other players of different strengths might do in a similar situation.

It seemed to me that the sudden imbalance in material threw him a bit. He seemed to force his position and turned it into a race to mate me, even sacrificing both Exchanges to give us practically material equality. I do think he may have given in to the draw too quickly though; after 46....Kb8, he has 49.c6! Rh7 50.c7 Rcc7 51.Qxe6, my e-pawn goes and right behind it is one of my other two pawns. Seems he'd have excellent winning chances at the very least.

Post edit: Ahh, nevermind. After 49.c6, Rc7 and everything is fine. Don't know why I couldn't see that before.

So I'm assuming the question has to do with "what should Black do after 16. a3?"

The choice you made - to exchange your Queen for two minor pieces - seems like a very poor idea to me in this game especially. However your opponent didn't exploit your weaknesses well at all and you managed to pull a draw out of it.

Look at the position after 17...Bxe3. Both your g6N and your e3B are far from the kingside. White has his Queen and both Rooks and two open files on to your king's castled position. Your King has no Pawn cover on the c file. The standard way to exploit your weakness would be for White to start threatening you every move and being very aggressive, because you need time to reposition your forces. However White gives you that time with his silly 19th and 20th Pawn moves.

What about 18. Rc6+? If 18...bxc6 then 19. Qa6+ followed by either Qxa7+ or Rb1+ depending on how Black moves his King. If 18. Rc6+ bxc6 19. Qa6+ Kb8 20. Rb1+ Nb6 then White can start pushing the a Pawn to win or displace the Knight.

I don't know if this line leads to a forced win, but your choice definitely seems to favor White here to me.

Well, what about the other line, the one where I just let him capture my bishop and go a piece down for practically no compensation? Wouldn't that line also considerably favor White? I was banking on the assumption that my opponenet would not know how best to handle this materially unbalanced position. It turns out that it paid off. Would you think my chances of escaping with a draw would have been even better if I just went a piece down?

I think with two Knights, two Rooks and a Queen, a Pawn majority on the Kingside vs an isolated Pawn, and a vulnerable White d-Pawn Black would have more opportunity to complicate the game and try for a win or a draw, yes. The position after Black's 17th move is pretty scary for Black. I think there's a lot more play for Black after 16...Ne7 17. axb4.
