1. e4 |
Freddy invited me to Gameknot to play some games in the Bryntse Gambit (or to use the name he made up, the Demolition Derby Attack). I gave a lecture on this variation at ChessLecture.com, called "Nuke the Sicilian! How to Sac Your Queen on Move Six and Win." This game is absolutely a wonderful example of how the attack should go -- but just when you think White is going to win, Freddy plays some great defensive moves and escapes with a draw. I would like to see some comments on where I went wrong. Move 41? 43? 44? | ||||

The "tabiyah" position, and the starting point for our game. | ||||

8... Kc6 9. Bxg4 e6 |
Probably best. Other alternatives are 9. ... Qd4 and 9. ... Qd6, but Black's biggest problem is lack of development. Note that 9. ... e5? is dubious because of 10. Nf7 Qh4+ 11. g3 Qxg4?? 12. Ne5+ -- the first and most basic trap in the "Demolition Derby Attack." | ||||

11... Qd4 |
Freddy's novelty. Pruess played 11. ... Bd6 here, and in my many games against Fritz the computer played 11. ... Qf6 every time. Freddy's move looks much more assertive, and so I had to figure out why the computer doesn't like it. | ||||

12. Nxe6 |
I looked at seven (!) candidate moves: N3xe4, d3, Nxe6, Bxe6, N5xe4, Ne2, and Nf7. I decided on this for two reasons. First, I really don't like having the queen in my face, and second, this seemed like the only way to profit from Black's playing ... Qd4 instead of ... Qf6. | ||||

12... Qd7 |
This was a surprise, and I realized now that I had been a little too superficial in my analysis on the previous move. I had expected 12. ... Qf6, when White can gain a key tempo after 13. O-O Re8 14. Nxe4. If 14. ... Qg6 15. N6g5! with two key points: 15. ... h6? 16. f5 trapping the queen, or 14. ... Rxe4 15. Bf3 winning the exchange. The point of 12. ... Qd7 is to not allow White to win a tempo with Nxe4, so now 13. ... Re8 becomes a serious threat. | ||||

13. d4 |
My first inclination was to play 13. Bh3, which I still think is okay for White. Then I started looking at this move, almost as a joke, and realized it was no joke! If Black takes either way, White gets lots and lots of piece activity, which is what the opening is all about. If he declines the pawn then White just gets a great bind after d5. | ||||

If instead 13. ... cxd4, then 14. Ne2 threatens N6xd4+, winning Black's queen. | ||||

14. Bf3+ Kb6 |
A little bit of a surprise to me, but 14. ... Kd6 15. Ne4+ Ke7 16. f5 also looks really good for White, with all of his pieces participating in the attack. After 14. ... Kb6 the position takes on a very forcing character, as White gets a long series of checks. | ||||

15. Nd5+ Kb5 16. Nc3+ |
An interesting moment psychologically. I had not yet worked out how White gets an advantage after c4+, and so I decided to play this move to see if I could tempt Black into either ... Ka5 or ... Kc4. On 16. ... Ka5 I was planning the spectacular line 17. b4+ cb 18. ab+ Kxb4 19. Nd5+ Kb5 20. Rxa6!?! ba 21. N6c7+, with amazing complications. Believe it or not, there is a good chance that Black will get mated on a1. However, Freddy indicates that he is willing to play for a draw by repetition. Interestingly, at this point he still thought that Black would have the advantage if White doesn't go for the draw. | ||||

16... Kb6 17. Nd5+ Kb5 18. c4+ |
A key point in the game. I think that 18. f5 is too slow, and 18. Nxf8 opens the position up too much. Even now I had not fully worked out the point of 18. c4+ -- but it just seemed like White's only try for an advantage. | ||||

18... Kxc4 19. Ne3+ Kb5 20. a4+ |
The next key point. When I played 18. c4+, my intention here was to play 20. Bd5. But this gives Black an important tempo to play 20. ... Nc7! Now on 21. a4+ Kb6! 22. Nc4+ Ka6! 23. Ne5 Qxe6! 24. Bxe6 Nxe6, Black has successfully fended off the White attack. Black is a pawn up, but more importantly Black can develop very naturally. White will win the pawn back but the best he can hope for is equality, and maybe even a slight disadvantage. However, this line showed me that it was very important for White to try to get the knight to e5. I therefore thought about 21. Nxc7 Qxc7 22. Qxc7 23. a4+ Kb6 24. Nc4+ Ka6 25. Ne5, which gets the knight to e5 without allowing a queen sac for two pieces. I could not reach a clear assessment after 25. ... Qd6 26. Be3 d2+! Nevertheless, as I sat down in front of the computer I was planning to enter the move 20. Bd5, but then I said, "Wait a minute, what about ...?" All that analysis of 20. Bd5 turned out to be wasted effort, except for one thing -- it showed me the importance of getting the knight to e5. | ||||

20... Ka5 |
Forced, as 20. ... Kb6 21. Nc4+ is mate, and 20. ... Kb4 21. Bd2+ Kb3 22. Bd5+ forces Black to give up his queen (for only ONE piece) to stop mate. | ||||
| | |||||
|
21. Nc4+ Kb4 22. Ne5 |
This is the point I suddenly realized on move 20 when I was sitting at the computer. Ironically, I had gotten to the position after 21. ... Kb4 previously in my analysis, and concluded there was no way White could play this line. He has two pieces en prise and he can't defend them both. It was only several hours later that I came back to this move and realized White doesn't HAVE to defend them both! | ||||

22... Qxe6 |
Poor Freddy doesn't have much choice about any of his moves during this part of the game. | ||||

|
23. Bd2+ Kb3 24. Bc3 |
Threatening 25. Bd1 mate. If 24. ... Nb4 25. Ra3+ Kc2 26. Bd1+ Kb1 27. Kd2 with mate next move. 24. ... d2+ is a possibility, but after 25. Kf2 Black will still have to give up his queen, plus the pawn on d2 is now a sitting duck. Freddy decides to give up the queen immediately, perhaps hoping that he might be able to hold onto the d3 pawn. | ||||

24... Qxe5+ 25. fxe5 |
With both queens off the board, you might expect the position to get simpler. But you would be wrong! Black's king remains nearly (but not quite) in a mating net, and one wrong step could mean his rapid demise. | ||||

25... Be7 |
(!) So far White has had most of the fun, but here Black plays an excellent move. I had assumed Black would play ... Rd8 or ... Nb4 because of the potential fork on b7, but those moves lose quickly to Ra3+ and Kd2, threatening b3 mate. 25. ... Be7 prevents White from carrying out that plan because of the check on g5. Freddy is not concerned about 26. Bxb7 -- he may have to sac the exchange, but he gets a tremendous initiative with his knight, his bishop, his rook, and his pawn on d3. Meanwhile, White gives up his best piece, the bishop on f3. NO DEAL! | ||||

26. Kd2 Bg5+ 27. Kxd3 |
(Reply to Ionadowman) I briefly thought that 26. Bd5+ c4 27. Bf3 was the solution, particularly in view of the exquisite variation 27. ... Nb4? 28. Ra3+ Kc2 29. O-O Bc5+ (Black can throw this check in or not, it doesn't matter) 30. Kh1 Rhf8. It looks as if Black has wriggled out, but now comes the rook sac 31. Rc1+!! Kxc1 32. Ra1+ Kc2 33. Bd1 mate. Unfortunately, there are two flaws. First, 26. ... c4 is not forced; Black can try 26. ... Kc2 and I couldn't find a clear win. Second, instead of 27. ... Nb4 Black can play 27. ... d2+ 28. Kxd2 Rad8+ 29. Kc1 Rhf8. You're right that Black has to sac the exchange, but look at the awesome compensation he gets after (say) 30. Bd1+ Rxd1 31. Rxd1 Rf2. How will White ever activate his pieces? This move was when I started realizing that this was not going to be an easy win. There are lots of exchange sacs that give Black tons of counterplay. Thus, I also had to reject 26. Bxb7? Nb4! 27. Bxa8 Nc2+ because Black's pieces just take over the board. Although risky, 26. Kd2 was the most consistent with White's principles for playing this opening, because it keeps the coordination of the pieces (keeping the two bishops on the board, connecting White's rooks, and even using the king as a fighting piece) and keeps mating threats alive. The fact that it also eliminates Black's potentially dangerous pawn on d3 is a nice bonus. | ||||
