Analysis by

    Here is a game where I go from worse, to much worse, to slightly worse, to winning, then to drawing.  It’s an interesting game nonetheless.

N. Solon - A. Zaremba
[A44/05] Old Benoni: Pawn Thrust
World Open, 1999
1.d4 c5 2.d5 e5 3.e4 d6 4.Nc3 
Not the main move in this position, but enough for a small advantage, in fact Julian Hodgson and Piket have employed this move with success.  This move aims to play a4 and establish the white king knight on c4, while Black usually gets to trade off his bad dark squared bishop White still keeps the advantage.  Main line here runs 4...a6 5.a4 Be7 6.Be2 Bg5 7.Nf3 Bxc1 8.Qxc1 Ne7 9.Nd2 Nd7 10.Nc4 [+=].  I didn’t know book here, but ...Be7 seemed obvious, in fact it’s bad due to 5.Bb5+! and Black is forced to play 5...Kf8, other lines run: 
A) 5...Nd7 6.f4 exf4 7.Bxf4 Ngf6 8.Nf3 0-0 9.0-0 a6 10.Bxd7 Bxd7 11.e5 and White gets the advatage. 
B) 5...Bd7 is bad due to just 6.Bxd7 Nxd7 7.Nf3 when White gets Black’s good bishop and Black is unable to trade off White’s dark squared bishop.
4...Be7? 5.h3? Bg5 6.Bg5 Qg5 7.Nf3 Qe7 [=] 8.g4? 
Weaking the dark squares too much, simply 8.g3 with the idea of Bg2, castles, and f4, is called for with equal play for both sides.  Now Black has the advantage.
8...Nf6 9.Bd3 0-0? 
9...h6 with the idea of Nh7 and Ng5 is better.
10.Qd2 Nbd7 11.Nh4? 
Not the right idea.  White should’ve continued with 11.a4 Re8 12.Nd2 Nf8 13.Nc4 Ng6 14.Qd2 Bd7 with a slightly worse position.
11...Nb6 12.Nf5 Bf5 13.gxf5 g6! 
Black wants to land a knight on f4 and that’s the only way to do it.
14.Rg1 Kh8 15.fxg6!? 
Hard to judge this move as it opens up the f-file for Black’s rooks and the outpost on f4 becomes very strong, but what else is White supposed to do?  On 15.0-0-0 gxf5 16.exf5 Nbxd5 [-+] and White has no compensation for the pawn.
15...fxg6 16.Qe3 Nh5 17.Be2 Nf4 18.0-0-0 Rf6? 
Allowing White his next move and some counterplay, more precise was 18...Rf7, if 19.h4 Black will just capture and White has no attack.  Hard to find a move for White after 18...Rf7, but unfortunately I played 18...Rf6.
19.h4! h5? 
Another inaccuracy, I underestimated Whites attacking chances here, thinking I was invincible with the knight on f4 I thought I could do whatever I wanted here, but that’s not true, Black has to be very careful.  More precise was 19...h6 20.h5 g5 21.Bg4 a6 22.Bf5 Nc4 23.Qg3 b5 [-+].
20.Rg5 Raf8 21.Rdg1 a6 22.Bf1 Kh7 23.Ne2 Nd7 24.Bh3! 
Whole sequence of moves is excellently played for White.  Now Black faces a tough choice between giving up his knight on f4 or letting the white bishop into the Black camp with a lot of potentially dangerous threats and combinations.  So...
24...Nh3 25.Qh3 R8f7 
Black has to be really careful here, as White has a lot of threats.
26.Qg2 
Now Rh5 is a threat as well as the obvious Rg6.  26...Rf2 loses of course.
26...Rg7 27.Rf1 Qf8 28.Ng1 
With the plan of bringing the white knight to g5.  Fortunately I had a good, far from obvious, reply.
28...Rf4! 29.Nh3 Rxh4 
Black sacrifices an exchange but gets enough compensation to maintain his advantage.
30.Rg1 Qf6 31.f3 Nf8?? 
A very bad move.  Black should’ve played b5 and had 2 extra tempi on the game.
32.Qg3 Rf4 33.Nxf4 exf4 34.Qh4 Nd7 35.R1g4 Kh6 
If I didn’t have this move it’s game over.
36.Rg1 Qf7?? 
An outrageous blunder, a common oversight though, I was thinking that there is still no way for White to play R5g4 because I would take the queen on h4, but I can’t so this sucks.  I should’ve continued with 36...b5 and attack on the queenside.
37.Qf2? 
37.R5g4 Ne5 38.Qg5+ Kh7 39.Rxf4 Qe7 40.Qxe7 Rxe7 41.Rf6 [++--].
37...b6 38.Qg2 Qf6 39.Qh3 Ne5 40.Rg2 Kh7 
Now Black has a decisive advantage.  White has no play and uselessly moves around while Black conducts an attack on the queenside.
41.Rf2 Nc4 42.c3 b5 43.R2g2 Ne5 44.Kc2 a5 45.Rf2 a4 46.Qc8? 
Loses on the spot.
46...Qh4! 
White must give the exchange back now.
47.Rgf1 Nc4 48.Re2 Ne3 49.Rxe3 fxe3 50.Kd3 Qh2 51.Kxe3 Qxb2 0-1.

A game full of mistakes and blunders, the overall ideas were right for both Black and White, while White misplayed the opening, his ideas were mostly right, but the execution needs more work, this was worse than Shaq at the free throw line.  Execution for both sides was terrible.
