Well, it’s time to bite the bullet, so to speak. The match was billed as a sort of showdown at the O.K. Corral and… I guess it kinda turned out that way… The Earp brothers showed up and mercilessly gunned down the people’s favorite Clanton’s. Too bad Boston was on the wrong end of the barrel this time. Come to think of it, weren’t the Clantons and McLaurys braggen on how they was gonna put an end to those Yankees. Hmmm… but that would mean the Earps were from the north, and the Clantons from the south and… I think we got it backwards somehow.
As it turned out, the Dallas Mavericks rode into to town… guns a blazin’… and shot the sheriff and his buddies before they could even pick up a weapon. At least, the aforementioned gunfight left the Earps wounded. Strangely, Boston’s proven championship caliber team went down with a thud in a battle that is the stuff of which legends are made.
Now, hand me that there shovel… I gotsta bury me some bodies… the first being everyone’s favorite 4th board. Deputy Ilya Krasik…

Position after 6… c5
Ilya’s next move is standard, but, I can’t say I like it much.
7. e4…
This leads to the type of game that Ilya seemed, in my own often erroneous opinion, quite uncomfortable playing. So, may I suggest two other continuations which I like very much.
The first allows White to get in d5, after which I’m sure Ilya would have played more confidently.
7. Bg5 h6 8.Bxf6 Qxf6 9. d5 Na6 10. O-O-O O-O-O
The second is a favorite type of gambit of mine… the one in which you give a pawn with no real prospects of getting it back. As an example, may I present the game Bayram – Invanchuk, 2002 which continued…
7.d5!? exd5 8.cxd5 Nxd5 9.Bd2 Nc7 10.e4 Nc6 11.0-0-0 Nd4 12.Qd3 Nce6 13.Kb1 g6 14.h4 h5 15.Ng5 Bg7 16.f4 Nxg5 17.hxg5 Qe7 18.Nd5 Bxd5 19.exd5 0-0-0 20.d6 Qxd6 21.g3 Qc6 22.Rh2 Rhe8 23.Bg2 d5 24.Bc3 Kb8 25.g4 hxg4 26.Rh7 Rg8 27.Re1 Nf5 28.Bxg7 Rxg7 29.Rxg7 Nxg7 30.Re7 Rd7 31.Qe2 Ne6 32.Qe5+ Kc8 33.Rxf7 Rxf7 34.Bxd5 Rf5 35.Qh8+ Rf8 36.Qe5 Rf5 37.Qh8+ Rf8 38.Qe5 Rf5 ½ – ½ drawn by perpetual check.
I’m sure Ilya would have been comfortable with this… a bit of humor here.
7… cxd4 8. Nxd4 Bc5 9. Nb3 Nc6 10. Bd3…
This is only equal and seems to lead to somewhat misplaced pieces on White’s side.
Better was 10.Bf4!… threatening to grab Black’s c5 Bishop and post a White Bishop on d6. After the obvious 10.Bf4 d6 11.O-O-O… White has the advantage.
10… O-O 11. Bf4 Nh5 12. Bd2?!…
This is a slight mistake.

I know, Knights on the rim… Still, it was time to settle for a draw with…
12. Nxc5 Nxf4 13. Nxb7 Qc7 14. g3 Nxd3+ 15. Qxd3 Qxb7 16. f4…
and a small chance to drum up something. After White’s last, Black has a chance to grab the initiative with 12… Qh4!? 13. O-O Nf6 14. Nxc5 bxc5 15.Nb5 Ne5
12… e5?
Oh, but not this self-inflicted gaping hole. Now, White has a chance to jump on top as the game continued.
13. Nd5 Nd4 14. Nxd4 Bxd4 15. O-O Rc8
| ![]() |
Position after 15…Rc8
What to do? What else… eliminate Black’s best piece. 16.Be3! Bxe3 17.fxe3!… gives White the advantage. Or 16.Be3! b5 17.Bxd4 exd 18.Qb3… works even better. By no means is White winning, but he is better.
16. g3?!…
Yeah, the Knight might some day go to f4… who cares. Now Black has a nice move to make use of his misplaced Knight. 16… f5! Yes, and the pawn cannot be take since White’s d5 Knight hangs to the pin on the c-file… and, to boot, the pawn threatens to advance. White’s best would seem to be… 16… f5 17. Bc3 Bxd5 18. exd5 Bxc3 19. Qxc3 e4 20. Be2 Qe8 with Black a scooch better.
16… d6?
No! No! No!.. which piece does this move free? Now White can move back on top with 17.Be3! Bxe3 18.Nxe3… and if 18… b5 19.Rad1 bxc 20.Bxc4… with advantage.
17. Qd1 Nf6
The game is equal.
18. Ra2…
Whoops! I spoke too soon. Black is better. After…
18. Rb1 Nxd5 19. exd5 f5 20. Qh5 e4 21. Be2 b5 22. b3 bxc4 23. bxc4 Ba6 24. Rfc1 Rb8
But, at least White’s pieces seem coordinated. After the games 18.Ra2… White never seems to get his pieces in order.
18… Nxd5 19.cxd5 f5 20. Qf3 fxe4 21. Qxe4 g6 22. b4 Kg7?!
This gives White chances. Black should go after the d-pawn with moves like 22… Rc7 threatening 23…Qa8 or 22… Qf6 to f7. Now, White should again play 23.Be6… to rid himself of that ridiculously good bishop of Black’s… But, alas, this is not in Ilya’s view at the moment.
23. Rc2 Rxc2 24. Bxc2 Qf6 25. Bd3?… (25.Ba4… put up a tougher fight) 25… Qf7

The d-pawn is lost… if Black wants it.
26. Bc4 Rc8 27. Bb3 Ba6 28. Qh4 Bxf1 {White resigns} 0-1
Oops! White can’t even lose the exchange by capturing.
Let’s call this the game of the cowardly Bishop who refused to go to e3.
Boston (0-1)
Second to fall was Boston’s Special Deputy Vadim (Doc) Matirisov, who is always prepared very well, although, because he is used only in spot starts, it was thought he could be a little rusty. As he was playing the higher rated FM Keaton Kiewra, this game was a “who knows” match-up. As it turned out, FM Keiwra was a little faster on the draw than we hoped…

Position after 8.a4!?
This position is more critical than it looks… and credit FM Kierwa for putting on the pressure so early. Since I play the Sicilian e6 opening as Black, I fully understood Vadim’s issue hear… and I have never had success with the early d5 as played here.
8…d5?!
Most games I looked at prefer 8…b4. I must say, I have never understood why. After reviewing this game, my guess is that White’s advantage in development shows to be just a bit too much after the game move. Let’s take a look at some options…
8… Ng6 At least this move does something to help black catch up in development.
9. axb5 (9. Re1 Rc8) 9… axb5 10. Rxa8 Qxa8 11. d4 cxd4 12. Nxd4 Nxd4 13. Qxd4 Be7
14. Re1 e5 15. Qd3 Bc6 16. Nd2 O-O and Black will be a tough nut to crack.
8… b4 9. d4 bxc3 10.d5…
Again, I must mention that I love gambits, but this one is just not quite enough. Unless some diligent reader can improve.
(10. bxc3 cxd4 11. cxd4 Nb4 and Black looks ok.)
(10. Nxc3 Nxd4 11. Nxd4 cxd4 12. Qxd4 Nc6 and again Black is fine)
In both options above, White has an edge, but, Black has a playable game… now back to the gambit…
10… cxb2 11. Bxb2 Nb4 12. Bb3 exd5 13. exd5 Nexd5 14. Re1+ Be7 15. Bxg7 Rg8
16. Bh6… and White just doesn’t have enough… I think.

Analysis Position after 16. Bh6…
Did I mention I like these types of gambits? Everything hangs on a thread. Black can’t castle, but White’s f3 Knight may hang in some variations. What is the plan… for both sides? Is there an improvement. If so, this whole 8…b4 may be just as bad as the game.
9. exd5 Nxd5 10. d4?! Be7 (10… b4!?)
Black could have tried to transpose back to the above variations.

White is now firmly on top and it will take the skill of Kramnik to save the game.
The move options for Black are slim and usually will lose the b5 pawn. They are…
16…h6 17.Qxb5 Qc7 and suffering on a pawn down.
16…Qc7 18.Nc6 g6 19.Nxb5… and more suffering

There are better forms of suicide, but this is as good as any. I can’t blame Vadim. I think I would want out of my misery here as well.
17. Nc5 g6 18. Nd7 Qb7 19. Nxf8 Bxf8
And Black has lost the exchange for a bad position. The game is lost.

{Black resigns} 1-0
So, the lesson here… always dodge the 8.a4!?… bullet with 8…b4… now I see! All those years and lost games… I might still be a master… Naaahh! 8…b4 is still too tough for me. Nice game by FM Kierwa. Boston (0 – 2)
This put the pressure on the top two boards as both were suffering very nicely on their own without the added knowledge that they must win at any cost… and to their credit, both Bostons top guns refused to go quietly and fell on their swords rather than accept a team loss. Well, maybe a bit dramatic, but, it’s been my experience in watching league games that players often accept draws when they see that they must win or the team loses… Maybe this team spirit is all we can take from this match… and maybe it’s the real reason Boston has been a perennial contender.
The next to go down was top gun GM Larry (Wyatt) Christiansen who had the better of a tricky opening against IM Jacek Stopa until…

However, White is solid here although I don’t know what he can do to stop Black’s doubling of Rooks on the d-file. I think Larry was trying to keep things complicated in order to drum up greater winning chances.
16. Ne3 Be6 17. Ng4 Bxg4
This is no more than equality… and Black can’t afford that… at least until he knows what is happening on the bottom boards. Both of which looked bad at this point.

Our top gun goes down and with him the match. A very interesting game and congratulations are due to IM Stopa for his whole concept. It’s not easy to beat Larry with a tactical variation.
Boston(0 – 3)
Now, only dignity lay at stake on Board 2 as Jorge (Morgan) Sammour-Hasbun was now in very deep doo-doo against IM Daniel Ludwig… but, as fate would have it, a shotgun blast from out of nowhere brought down our final hero…

The book says 11… Rg8 or 11… Rb8. Mikhail Tal even won a game as Black with the dubious 11…b5. Obviously, IM Ludwig has something special in mind.
Up to now, both sides have been playing best moves according to Fritz.
12. Qg3 Nc5 13. Bf3 e5
Again, best according to my buddy Fritz.

But, this is only second best although it does keep an advantage for White. Fritz gives the following…

An amazing position and a very good example of why computers are so strong now. Proper play from here consists of the incredible… 18.Ka1… to prevent the equally incredible 18… Na4 (similar to the game) and White cannot take or even move his c3 Knight.

and White is better. Incredibly, 18… Nxc3 is a mistake due to… 19. f6! g6 20. fxe7 Nxd1 21. exf8=Q+ Kxf8 22. Qxd1… and White wins.

Interesting article, as always. I just wanted to comment on your suggested 7th move alternatives in Krasik’s game, because I think they’re a little unconvincing. After 7.Bg5, I believe that Black has two better moves than 7..h6?! — the first is 7..cd 8.Nxd4 Nc6, not fearing 9.Ndb5 Qb8 (for the hedgehog players out there, 8..a6 9.e4 d6 also looks fine); the second and critical line is to grab a pawn with 7..Bxf3(!), 8..cd, and 9..Nc6, which IMHO looks quite good.
Your second line, 7.d5, is more established. In fact, I’ve played it myself, but ultimately I just don’t believe in it. There’s no concrete refutation, but if you look at high-level games, it scores poorly. Even the game you quote looks slightly better for Black out of the opening (extra pawn and the d4 square). It’s interesting to compare this to a similar QID pawn sac, namely 1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Ba6 5.Qc2 Bb7 6.Bg2 c5 7.d5!?, which is currently popular. Here White’s bishop is already active on g2, and White hasn’t wasted a move on a3, so the sacrifice makes a lot more sense. Still, I shouldn’t be too harsh — 7.d5 in the Petrosian system has been played by a lot of strong players, and it’s certainly viable. I just think it requires more energetic play than most gambits do.
Keep up the good work!
Mark, you got the order wrong, Vadim lost first, then Ilya, then Larry then Jorge.
Oops! My memory ain’t what it used to be.
Mr. La Rocca writes in the Krasik-Yang game,
“What to do? What else… eliminate Black’s best piece. 16.Be3! Bxe3 17.fxe3!… gives White the advantage. Or 16.Be3! b5 17.Bxd4 exd 18.Qb3… works even better. By no means is White winning, but he is better.”
But any reasonable black 17th move after 16…Bxe3 17. fxe3 is equal. For example, 17…Bxd5 then g6, or 17…g6 first, or simply 17…d6. All equal. I would actually be happy as black to see 16. Be3 Bxe3 17. fxe3 as it’s structurally suspect.
Going back, black’s 12th move 12…e5 is fine with level chances and did not warrant a question mark symbol. Black also had 12…Qf6 13. O-O Nf4 (equal) but 12…e5 was of equal worth.
Before 12…e5? White’s pieces seemed misplaced. Black need only bring his queen to the Kingside and start provoking weaknesses. …e5 doesn’t lose but it is what gave White the option of opposing Black’s strong bishop. As to why double the pawns… just to create some winning chances. Of course, Black will need to trade White’s strong Knight and the pawns temporarily stop Black’s Knight. The position is drawish, but before 12…e5, I liked Black’s building initiative. Afterwards, I like Whites chances for queenside expansion, especially after the d5 Knight is traded. It is a swap of the initiative after 12…e5 and that I didn’t like. I stand by 12…Qh4 a probing/waiting move.
