1. d4 d5 2. c4 e6 3. Nc3 c5 4. cxd5 exd5 5. Nf3 Nc6 6. g3 Be6 7. Bg2 Be7 8. O-O Nf6 9. Bg5 { 9.Bg5 made me nervous, but apparently it is not a good move.
I see that it threatens (for instance after 9...O-O the move 10.dxc5 Bxc5 11.Bxf6, where we would have to choose between Qxf6 (hanging the d5 pawn) or gxf6, with a weaker structure.
However, it is important to see (I did not) that after 11...Qxf6 12.Nxd5 Black still has Qxb2.
Visualizing that position I see:
(1) White's knight on d5 poses no immediate threat.
(2) Material is equal.
(3) The center has desintegrated, and I'm in an open position with the bishop pair.
(4) Rb1 fails to Qxa2 with tempo on the d5 knight (so Rxb7 cannot occur).
(5) Probably White's move is Nf4 pressuring my bishop on d7, after which Rfd8 etc. } 9... Ne4! { Instructive way to resolve the tension. As commented, castling was not bad. } (9... a6 10. dxc5 Bxc5 11. Bxf6 Qxf6 12. Nxd5 Bxd5 13. Qxd5) (9... O-O 10. dxc5 (10. Bxf6) 10... Bxc5 11. Bxf6 Qxf6 12. Nxd5 Qxb2 13. Rb1 (13. Nf4 Rfd8 (13...

But what's White's idea with Bf3? He realizes that if Black's bishop on e6 disappears, the defense of the c4 pawn would weaken, difficulting the desired avance a5-b4. So he wants to play Bg4, where the trade is force because Black does not have Bd5.
That is why the correct move is Rd8! Then if Bg4 Black is Bd5. } (20. b3 Qa5! 21. b4 Qc7) 20... Rfd8! (20... a5 21. Bg4) 21. Rd1 Rxd1+ 22. Bxd1 Rd8 23. Bf3 g6! { Never in my life would have this move occurred to me. I was again looking at a5. Why do I rush in winning positions?
(1) g6 threatens Bd5, winning a piece, since Qg4 is met with f5.
(2) Gives breathing room to the king.
(3) Prepares Bf5, activating the bishop greatly. } 24. Qc6 Qe5! (24... Qd6 { does not work because after } 25. Qxb5 (25. Qxd6 Rxd6 26. Rc2 { and it is uncelar how to make progress. } 26...

Rc1 { Threateening Rc2. } (32... Rxb2 { Does NOT work. One has to consider in to the obvious variation that, since Black gave up a rook, White can give up his rook as well.
So after 33.Rxb2 c3 34.Rb1 b2, Black does not have to move his rook (which leads to unavoidable queening), but can play 35.Bd3! Then the only sensible move is 35...bxb1Q 36.Bxb1.
In the final position, rooks have disappeared, Black has a pawn on b3 and White's bishop sits on b1. Material is equal, but Black will never queen the b3-pawn. A draw. } 33. Rxb2 c3 34. Rb1 (34.

What did I learn from this game? } *
