1.d4 d5 2.Bf4 Nf6 3.e3 Bf5 4.Nf3 e6 5.Be2 So far, so good! Both sides have used every tempo to develop something. White's last is a little conservative, but it gets the bishop out of the way so he can castle. 5.c4, attacking the black center and preparing to recapture with the bishop (5..dxc4 6.Bxc4) was good.
5...Bb4+ Check! Check! Wow, I played a check! Groan. I call this a "check in one." White blocks the check with an attack on the bishop. You might try to justify this with how the c3 pawn will take the b1 knight's best square away, but the time lost by the bishop compensates and white can later play c4 and put the knight on c3 anyway. And d2 is a fine square for the knight as well.
6.c3 Ba5 Ack. What future does this bishop have here? It's biting on granite on c3 and will need several moves to get back into action with something slow like ..c5 and ..Bc7. Both ..Bd6 and ..Be7 kept the piece active. Keep you minor pieces on good squares, or at least on squares that can become good after some pawn breaks.
7.Nbd2 Nc6 It might not seem related, but this makes it even harder to rehabilitate the bishop on a5. This move blocks in the c-pawn, which needed to chip away at the strong white center and which needs to get out of the way so the bishop can return to civilization via c7. It's a natural developing move, but it actually does more harm than good. White's Ne5 was not an immediate threat, so this knight should have either waited for ...c5 or just gone to d7 directly.
8.0-0 White has made every move count. His pieces are out, his center is solid, and his king has castled to safety. What more could you ask from eight moves? True, his e2 bishop is a little passive, but let's not get too picky.
8...0-0 9.Ng5 The dreaded one-piece mating attack! What is the point of this move? Even if we give white another free move here there is nothing! h7 is defended twice, this move is completely pointless.
9...h6 Justifying White's premature 'attack'. This weakens the black kingside for no reason at all. Black doesn't gain a move with this, it was his move anyway! Keep the f, g, and h pawns on their original squares in front of the king unless you really have to move them.
10.Ngf3 Re8 11.Ne5 Moving the knight for the third time in a row just to exchange it? White has more space and better pieces, and now he wants to help Black by swapping off that bad knight on c6 for the good one on f3? You can't always win by just moving the same pieces around. You need to advance pawns and also get your heavy pieces into the action. It was time to grab some space on the queenside (and attack that stray bishop on a5) with 11.a4!, threatening b4 and a5, winning the bishop. If you can gain space without weakening your position, do it!
11...Nxe5 12.Bxe5 Nd7 Excellent. Black immediately threatens the well-placed bishop and might even grab control of the center with moves like ..f6 and ..e5 if White isn't careful.
13.Nf3 White is willing to give up his bishop pair in order to gain a strong knight on e5. Still, this is too much simplification to expect any real advantage. You need to keep pieces on the board to attack anything.
13...b6?? I can only imagine that Black wanted to play ..c5 next and recapture with this pawn. That this moves loses a piece instantly was not considered (by either player). Black cuts off his bishop and now b4 wins the piece. [ 13...Nxe5 14.Nxe5 c6 with ..Bc7 next.]
14.g4?? Huh? Not only does White miss the free bishop on the queenside, he decides to give up a pawn on the kingside with this crazy thrust. He opens up his own king for no reason at all. [ 14.b4 ]
14...Be4? Why not take a free pawn? Black decided to buy whatever White was selling instead of calculating for himself. He panicked when his bishop was attacked and probably didn't realize he could just capture the pawn.
15.Bd3? Still ignoring the win of a piece with b4.
15...c5! After many delays Black finally gets in his dream move! This prevents b4 and attacks the white center.
16.h4? We could only expect this after g4, but that doesn't make it any good. If the white king were castled on the queenside and safe on b1 or c1 this might make sense, but now it's just making his own king vulnerable. The white pawns lack protection and when they go, so will the white king they were supposed to be protecting.
16...cxd4 Losing time and again making the bishop vulnerable to b4. It was time to go on the attack. [ 16...Bxf3 17.Qxf3 Nxe5 18.dxe5 Qxh4 Black has an extra pawn and his structure is in great shape compared to the mess White has. White has chances to attack with moves like Kg2, Rh1, g5. 19.Kg2 c4 20.Rh1 Qe7 21.Bc2 b5 Black is going to bring his bishop back to c7. White will have to throw the kitchen sink at the black king and pray.]
17.exd4 The rest of the game highlights a few basic concepts. Black refuses to capture the powerful bishop on e5. Both sides ignore the bishop on a5, which has more serious consequences for Black since he is basically playing down a piece. An inactive piece is like no piece at all! White didn't even need to win it with b4 because Black never used it! Later, Black weakens his own kingside pawns and is quickly wiped out.
17...Bxf3 [ 17...b5 The important thing is get the bishop back into the game. The pawn isn't worth as much as that bishop. 18.Bxb5 Bxf3 19.Qxf3 Nxe5 20.dxe5 Rf8 Material is equal but White will have a hard time justifying his pawn-pushing on the queenside. The h4 pawn is hanging and the white king is wide open. Black will hit the white e-pawn with ..Bc7 and can even go for his own kingside attack with ..f6. Black also has the open b and c-files to attack down with his heavy pieces.]
18.Qxf3 Qxh4 19.Kg2 Rf8 TAKE THE BISHOP! PLEASE, JUST TAKE IT!! AAAAHHHHHH!
20.Rh1 Qe7 21.Bg3 Too passive. Bf4 threatening g5 was logical.
21...f6 22.Bh4 Qe8 23.Rae1 Qf7 24.Bg3 e5 25.Qf5 g6 [ 25...e4 ]
26.Qxg6+ Qg7 27.Qxh6 Qxh6 28.Rxh6 exd4 29.Reh1 Kf7 30.Rh7+ Ke6 31.Bf5# The bishop still sits on a5 like a monument. 1-0
