Carolina Cobras Blog: October 2010

Being paired to play against the very strong, yet untitled(!) Jorge Sammour-Hasbun on Week 8 of the US Chess League 2010 was both a challenge and an opportunity for me. Jorge resume is awesome (Dos Hermanas, anyone?) and his exploits in the chess board are well known. Mine? Don’t bother. Arriving late also did not bode well for me. But play we must, so here we go …

Sammour-Hasbun,Jorge (2603) - Agner,Carlito (2251) [E86]
USCL Carolina vs Boston Internet Chess Club (8), 13.10.2010

1.d4 (1:29:53)

I was expecting 1.e4. Luckily, before leaving home, I thought, what if he opens 1.d4? So I hastily looked in at newinchess.com and found that Jorge likes the Saemisch treatment of the King’s Indian Defense. I remembered the famous Karpov-Kasparov, Linares 1993 game when all the White pieces ended in the back-rank at one point, so I looked it up and that became my inspiration. My main idea for the game was to make it complicated enough so that chances for mistakes are ever present. I also decided to include the times on the notation to show the effect of it to our play. So we blitzed out the following moves …

1. … Nf6 (1:24:11)

The time deficit of 5 minutes was due to me being late.

2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0

6.Nge2 (1:29:28) Here, I thought, not 6. Be3? Maybe he was trying to do some transposition, so ..

6. … Nbd7 (1:24:17) After a minute and 25 seconds look.

7.Be3 (1:27:32) Ahh .. here we go, back to the path.

7. … e5 (1:24:33) I have more time than I started!

8.Qd2 (1:19:51) It took Jorge 8 minutes for this move. This is still theory so, I wondered what the hold up was.

8. …c6 (1:23:10) A minute think to make sure still on track.

9.0-0-0 (1:19:29) Ok, no Karpov-Kasparov Linares, 1993, as White played 9. Rd1 on that game.

9. …a6 (1:22:39).

10.Kb1? (33:29)

The question mark is for the time spent on the move. This took 46 minutes and 30 seconds! I don’t know what was going on. One thing was that, I was making my moves pretty fast up to this point because I was still in my little preparation, so I think, and this is a guess, Jorge must be thinking I had something prepared specially for him at this juncture. But, really, I just wanted to get out of the opening with a playable middle game!

10. …b5 (1:10:39). I took a 12 minute think here to decide what to do after 10. … b5.

In a game where castling is on opposite sides, the game is a race to the King! So, Forward, March! This is still part of the standard line I looked up.

11.Nc1 (32:53)

As expected. Now I had to decide what to do next.

11. … b4 (1:05:06) I spent six minutes here. This was not an easy decision, but a practical one. After 11. Nc1, White is now ready to take on e5 again (dxe5) and if Nxe5 as planned, simply take on d6 as the c4 is not hanging anymore. I looked at Qe7, Re8, and Rb8, but considered all three as not active enough for black. In Shirov-Kasparov, Dortmund, 1992, Kasparov went 11. …exd4 12. Bxd4 Re8 13. Bxf6 Qxf6 14. Qxd6 Qxd6 15. Rxd6 Ne5, with a nice pressure on the queenside. 11. … exd4 is the most popular line.

12.Na4 (29:47) Three minutes given up here. The other option is 12. N3e2 Qc7 13. Nb3 exd4 14. Bxd4 Ne5 with a roughly equal game.

12. …exd4 (1:02:00)

Three minutes spent here. With the c3 knight out of the way, I wanted to get a clear diagonal for my g7 bishop.

13.Bxd4 Qa5 14.b3

Another line here is

Now, I have the open a1-h8 diagonal. Question is, with the white bishop at d4, can I get control of it? But first things first, so …

14. ….Bb7 (54:22) Six minutes used. Developing and threatening to open the center with d5.

15.c5! (11:59)

Seventeen precious minutes used. Getting critical on time. I thought this was a good move. White sacrifices a pawn to get a good post for the white-squared bishop, and it also stops my plan dead on its tracks.

15. …Nxc5 (50:12) Four minutes used. Asking White the question, which piece to trade?

16.Bxc5 (10:02) Another 2 minutes used up.

16. … dxc5 17.Bc4

Here I paused to re-assess the situation. White has finally the developed the bishop, but it costed him a pawn and the guardian of that LONG DIAGONAL. I thought here, black must be okay. Now how to proceed? Okay, take the open file …

17. …Rad8 (49:04). As the sequence was forced beforehand, I already planned 17. … Rad8, thus I used up only 1 minute and 46 seconds for this move.

Proving the richness of the position, my friend Fritz here finds 17. … Nd5! 18. exd5 cxd5 19. Bxd5 Rad8 with a complicated game ending to equal after 20. Bxf7 Kf7 21. Qf4 Bf6 22. Qc4 Kg7 23. Qxc5 Qxc5 24. Nxc5 Bc8 25. N1d3 Bf5 .

18.Qg5!

White is finding the most active continuations now. He threatens to take on c5 and the knight at a4 is suddenly a menace at c5.

18. …Nd7 (44:32) Five minutes spent here. The other option I thought about was 18. … Nd5 19. exd5 cxd5 20. Bxd5 but I could not find the continuation after this. Fritz later showed 20. … h6! 21. Bxf7 Kxf7 22. Qxc5 Nxc5 23. Nxc5 Bc8 with an equal evaluation.

19.Nd3 (6:16) Three minutes used up. The time is getting critical and the position is still complicated.

19. … Bc8 (38:15)

I used 6:47 here to redeploy my bishop stuck on the queenside. A funny looking position for my Bishop and Rook, both are looking at the shiny backside of my Knight. I did not have a nice feeling of my game at this point.

20.h4 (2:39)! Four minutes and seven seconds used. Very critical on the time! My thought here is that ‘Here he comes. And my pieces are still stuck in the muddy queenside!’.

20. … Qc7 (32:33) Six minutes used. Time to regroup in aid of the king! I cannot push the queen out with h6, as he simply takes on g6.

21.h5 (1:10)! 1:59 used. How long can he keep this up?

21. …gxh5?? (26:52). With enough time, I blundered. 21. … h6! 22. Qg6 Kh8! and black is ok.

22.Qxh5 (0:36) Thirty six seconds left for him. The time-pressure now made him miss 22. Rxh5! Which Fritzie evaluated as winning for White.

23. …h6 23.Naxc5 Nxc5 24.Nxc5

And here Black missed 24. Qxc5 with advantage, again, due to the time pressure.

24. …Qf4 (25:20). I had seen 24. … Qf4 earlier so I did not bother to check again. 24… Rd1 25. Rd1, Qg3! and Black can claim a little advantage.

25.Nd3 (0:54). Using the increment, White is able to increase his time available.

25. … Qe3? (24:25) Again, to the time pressure, I made this move after 1 minute and 25 seconds deliberation. 25. … Qf6 26. e5 Qf5 27. Kc1 c5 28. Qf5 Bc5 Black is still in the game.

26.Rhe1

26. Ne5! Be6 27 Be6 fxe6 28 Qg6 +-

26. …Qd4 (20:54).

Four minutes used after realizing I should have played 25. …Qf6 instead.

27.e5 (1:23) And White is winning already.

27. …Qc3 (18:39) I was not happy with my position here. 27. … a5 and Black has to find 28. f4 with still a winning edge.

28.Rc1 Qd4 (14:13). Another four minutes wasted in disgust. 28. … Qd2 29. Rc2 Qg5 30. Qg5 hg5 ends up with White still having the advantage. I rejected it offhand as I wanted to keep the Queens on the board to keep my chances alive.

29.Nxb4 (2:16). Playing mainly the increment in the five moves, White was able to increase his available time to 2 minutes and 16 seconds! Also winning for white is 29. Re4 Qb6 30. Nxb4.

29. …Qf4 (14:20) Played quickly. This led to … 30.Nxc6? (1:58). Having given himself some time, White took a breather and made the most obvious move. But this gives away the winning advantage. He had to find 30. g3! Bf5 31. Nc2 Bc2 32. Rc2 Qg3 33. Qh1 Kh8 with a complicated game but still the advantage toWhite.

30. … Bf5! (6:49)

Eight minutes spent finding this only move to get back to equality!

31.Kb2 (2:06) Qd2+ (3:09) Four minutes used up. We are now both in time pressure! Also possible is 31. … Bxe5 leading to the same line next.

32.Ka3 (2:08) Bxe5!

(1:55) The exclamation is for the surprise and aesthetic value. I liked this move. Pieces are hanging everywhere. But with exact play, this is just good for equality.

33.Rxe5? (0:37). Cracking in time pressure. White took 2:01 minutes. The correct move is 33. Qxf5 which leads to perpetual after 33. … Qb2 34. Ka4 Qa2 35. Kb4 Qd2 36. Ka4.

33. …Qxc1+ (2:04).

34.Ka4 (0:45) Bd7 (2:24). Now black is claiming a slight advantage.

35.Qg6+ (0:49)

35. Rc5 and black is still claiming a slight advantage after 35. … Qf4.

35. …Kh8 36.Qf6+ (1:05) Kg8 (2:39).
