  Honza Cervenka: Chessgames.com, this nice miniature is a game of GM Jaroslav Sajtar. His opponent was Bogdan Sliwa

By the way, there are four different files with games of Jaroslav Sajtar in the database.

Sep-01-06  AbhinavAsthana: Honza, can you tell me why did black resign after the 12th move?

  Honza Cervenka: <AbhinavAsthana> It's easy. 12...Qxe6 is the only move now and it loses the Queen.
Sep-02-06  AbhinavAsthana: <Honza Cervenka>Thank you. I didn't notice that.
Dec-30-07  msikma: Of course, the blunder here is 10...Qe7. In case Sliwa had played 10...Qb6, he would have been fine. I'd happily play that position.

Dec-30-07  msikma: What I also just realized is that there's an interesting continuation with 10...Qb6 11.exf6 gxf6 12.Nxf7?! cxb2 13.Bxb2 Qxb2 14.0-0=.

Dec-30-07  Whitehat1963: <msikma> Your final diagram doesn't look like equality to me, but then, my chess blindness has been confirmed for me on dozens of occasions. Still, it "looks" to me like white has a significant initiative in that position.

  whiteshark: <msikma: What I also just realized is that there's an interesting continuation with <10...Qb6 11.exf6 gxf6 12.Nxf7! cxb2 13.Bxb2 Qxb2 14.0-0=>>

To continue your line: <14...b5 15.Qd1 bxc4 16.Qh5>

and white should have enough initiative for the material.

Jan-01-08  msikma: <Whitehat1963> I've taken another look at the position after the imaginative 10...Qb6 11.exf6 gxf6 12.Nxf7?! cxb2 13.Bxb2 Qxb2 14.0-0. I personally think that this is about equal.

Let's see what the possible continuations are. Personally, I think that the most important threat is the rook, which can give check on e1. The idea here is that black defends, then white brings his queen over to d1 and gets ready for a crushing attack. Getting the queen to the protected d6 square would probably mean the end of the game, as black has no real way to defend there.

So white indeed has some major opportunities here.

But the problem for white is that the opportunities he has can't really come to fruition after 14...b5!

Let's take a look at what white can do. The most obvious counter is to take the pawn with the bishop (taking it with the queen is no good: 15.Qxb5 Qxb5 16.Bxb5 Kxf7 and white is down two minor pieces for absolutely no positional advantage). This means that the knight cannot remain where it is, however. Once the knight falls, white's advantage just disappears, and there's no real way to prevent that. So the bishop takes the pawn with 15.Bxb5, then the king takes the knight on f7, then I would presume to see 17.Qe4+ Kf7 18.Qxa8 Qxb5 19.Qxc8 Nb6.

Let's see how that would look:

The way I see it, both sides have good play here. I'd even rather play black in this position.

Another thing that white could do is the 15.Rfe1+ (again, after 14...b5!). Black blocks the rook with 15...Ne5 (which seems better than 15...Be7) and then white continues with 16.Qd1. Black takes the bishop with 16...bxc4, and now white's knight is no longer defended, so it's used to finally take the rook on h8. That would look like this:

To me, this too looks like equality, more or less. I think white has a slight advantage here, but nothing too serious. White will include his other rook in the attack and try to break in through the middle, but black has some serious counterplay and a dangerous looking pawn, not to mention two bishops.

So, it still does look equal to me.

Jan-01-08  msikma: <whiteshark> well, you're right. That's a very nice continuation. I had been thinking about following that move up with 16.Re1+ at first, but it's kind of stupid that I missed 16.Qh5.

That's indeed a very good move, and things are not looking good for black at that point.

But I still think that it's not all as bad as it seems. I'd presume there'd be a continuation like 16...Rg8 Rfe1+ 17.Be7 Qxh7 and then black has a beautiful rook sacrifice with 18...Rxg2+?! Kxg2 19.Qb7+ 20.Kg1 Qd5 for some interesting counterplay opportunities.

Black still has a bunch of opportunities here even though he's definitely at a disadvantage.

Jan-01-08  Whitehat1963: <msikma>, after 20. Kg1 Qd5, I'd play 21. Nd6+ (21...Qxd6 22. Rd1 black queen moves and 23. Qxe7#)

So how do you defend after 21. Nd6+?

Jan-02-08  msikma: <Whitehat1963> I would simply play 22...Kd8 to avoid an eventual Rxe7, and then you would take my queen in exchange for your rook.

Then it's two bishops, a knight and a rook against a rook and a queen.

Jan-02-08  msikma: Maybe an interesting continuation for white is 21.Qg8+ Nf8 22.Rad1 Qxf7 23.Rd8+ Kxd8 24.Qxf7 and black has lost its queen. Black plays 24...Be6 (or 24...Ne6, but this is bad) to prevent 25.Qxe7#, and then white could try to go for 25.Rxe6 Nxe6 26.Qg8+ and then black has to play 26...Bf8 and lose the knight in order to prevent losing the rook:

Another thing that white could do is 25.Rd1+. Black would probably defend with 25...Bd7, as all its pieces would be defending each other in that situation. Any other move and black's already miserable position just falls apart.

Then white plays 26.h4 and begins marching towards the eighth rank.

Jan-02-08  Whitehat1963: <msikma> Back to your diagram (fourth from the bottom) after 20. Kg1 Qd5, I'd play 21. Nd6+. And you'd reply Kd8. What then after 22. Qxe7+ Kc7 (forced) 23. Nb5+?
Jan-08-08  msikma: <Whitehat1963> After 21.Nd6+, the position is the following:


click for larger view

The knight is undefended and will be taken by the queen.

Jan-08-08  Whitehat1963: <msikma>, After 21...Qxd6, I play 22. Rad1!
Feb-02-08  msikma: <Whitehat1963>, after 22.Rad1, black needs to play 22...Kd8 in order to be able to take the white rook after it takes the black queen. Then we get 23.Rxd6 Bxd6 and the following diagram:


click for larger view

So what should white do now? Black has lost his material advantage, but he doesn't have a bad position. White can't continue the attack right away, I think. At least I don't see an easy way to do it right now.

Feb-04-08  msikma: Which, coincidentally, is the exact same result as shown in my first comment of Jan-02-08!
Sep-08-08  bunbun: Interesting discussion msikma and Whitehat1963! What do the computers say?

I think sikma's attitude is a good one to have regardless. I would probably be among those who would consider the game "won" after 10...Qb6 and fritter away the initiative and the game.

Aug-28-12  LoveThatJoker: Deep Fritz 13's Opening Book states that Black failed to capitalize on his chance to get a good game after 9. Bxc4? dxc3 10. Ng5 Qb6! when Black has a < > advantage.

Objectively much better for White is 9. exf6 dxc3 10. Bxc4 Qxf6 11. Bg5 Qc6 12. O-O-O cxb2+ (12...Qxa4? 13. Rhe1+ Be7 14. Rxe7+ Kf8 15. Rxf7+ Kg8 16. Rfxd7+ Qxc4 17. Rd8+ Kf7 18. Ne5+ Ke6 19. Nxc4 ) 13. Kxb2 Be7 14. Rhe1 f6 15. Bb5 Qb6 16. Kc1 fxg5 17. Bxd7+
