1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 h6 6.Bh4 0-0 7.Qc2 c6 8.cxd5 cxd5
Usual is ...exd5.

9.Nf3 Nc6 10.a3 a5
Was b4 really a threat?

11.Bd3 Ne8 12.Bg3
I did not want to trade and open up his pieces. If now ...Bd6 I would at least have considered Ne5.

12...f5
Way too loose. Better would be ...Nd6 or maybe even ...Bd6.

13.Rc1
I was happy with this move. The idea is to take advantage of ...cd5 by invading on c7.

13...Nd6 14.0-0 g5 15.Ne5 Nxe5
[15...f4 I I spent a long time making sure the "sacrifice" was sound. Black could try ...f4, "trapping" the bishop. 16.Bh7+ Kh8 17.exf4 gxf4 (17...Nxd4 18.Ng6+ Kxh7 19.Nxf8+ Kg8 20.Qh7+ Kxf8 21.Qh8+ Kf7 22.Qxd4 ) 18.Ng6+ Kxh7 19.Nxe7+ Kh8 20.Ng6+ Kg7 21.Bh4 ]

16.Bxe5 Bd7 17.Qb3 a4 18.Qd1
Eyeing h5.

18...Qe8 19.Qe2 Qf7 20.Bb5
Not best, and almost throws the advantage away, if not for a nice sacrifice. Better was Nb5 here... and I even saw why (...Nc4 by black), but for some reason I just reached for the bishop.

20...Bxb5 21.Nxb5 Nc4 22.Rxc4
Is this sound? Well, once I saw the idea I really liked it. I will get at least a knight and a pawn for it, and a4 and b7 remain weak. If i can net just one of the queenside pawns, then the sacrifice will pay off in bushels. Using that rationale, this move may deserve an ! Also, all my pieces will be in play and have a purpose, especially considering the possible d5 break.

22...dxc4 23.Qxc4 Rfc8 24.Qd3 Rc6 25.Rd1
d5 right away might have been best.

25...Bf8 26.d5
! the idea is to split up the pawns andhave targets on d5 and f5.

26...exd5 27.Nd4
! Get f5 first, round up d5 later.

27...Rc4 28.Nxf5 Rac8 29.Bc3
White's control over the kingside is impressive, but even the weaknesses on d5 and the queenside remain. Black's position is hard to hold, despite the material... "advantage" (?).

29...b5
Trying to solidify, and maybe break on b4. Very logical, but white's play comes through so quickly.

30.h3
It is necessary to make luft beefore taking on d5, or maneuvering the knight away.

30...R8c6
The last move before time control, and not very strong. Now both Nd4 and Qxd5 give white a small edge.

31.Nd4
[31.Qxd5 Qxd5 32.Rxd5 I avoided this because I feared Bxa3, but that doesn't work at all. 32...Bxa3 (32...R4c5 was much better for black. 33.Rxc5 Bxc5 ) 33.bxa3 Rxc3 34.Ne7+ ]

31...Rf6
?? Now white wins the exchange back, and black still has many weaknesses.

32.Nf3 Rxc3
?? A second blunder, and probably the losing one. After fighting a difficult, defensive battle, it is understandable that black may have been shaken by ...Rf6. [32...Rd6 was much better. 33.Ne5 Qe6 34.Nxc4 dxc4 35.Qc2 Rxd1+ 36.Qxd1 And white is only slightly better.]

33.Qxc3 Bd6 34.Qd3 Rf5 35.Qxb5 d4 36.Qe2 Qe7 37.Qc4+ Rf7 38.Qxd4
The rest of the game can pass without comment.

38...Bc7 39.Qxa4 Rxf3 40.gxf3 Qe5 41.Qc4+ Kf8 42.f4 Qg7 43.Qc5+ Kg8 44.Qd5+ Kh8 45.Qd4 gxf4+ 46.Qxg7+ Kxg7 47.Rd7+ 1-0
