Hebden - Howell

16..Da6 is reckoned to be worse than 16..Db5 and the position is unclear.

After 18..Se5 19. Sc5: Lc5 20. ab: Lf2+ 21. Kf2: Db6+ 22. Kg2 Td5: 23. De2 is about level according to Deep Rybka Three.

Not sure that Howell is any more than level. He might well win anyway of course.

Hebden-Howell is still well within existing theory.

You're right Justin. I'm very surprised by this - the variation was discussed in New In Chess yearbook 87, pretty much the only place it has appeared, so I would have expected Andrew Greet to have looked at this when he chose to take up the Kb1 variation!? Maybe I give the 'professionals' too much credit :)

Talking of existing theory, whatever happened to 17.dxe6 in the Hebden-Howell line? Pedersen gave it an exclamation mark nine years ago...

None of the big boys have gone near it for many years so there must be a problem with it. Sometimes these lines are a victim of fashion and reappear again after a while, but with the super-sharp variations, if Fritz and Rybka say it's good we would have seen it by now I think!?

Well, Fritz suggests that 25...b3 and white has +0.22, which is equal enough. Black does seem to have all the pressure at the moment, though. If I were black here though, I'd probably play a5.

I have twelve games with 17. de:
The score is +6 -4 =2 to White so far.
Highest rated player with White was 2358.

This position has been seen before.

25...a5 26.b3 a4 27.h4 axb3 28.Bg5 Qg6 29.Rc1 b2 30.Rxc4+ Bc5+ 31.Nxc5 b1Q+ 32.Kh2 Nxc5 33.Rxc5+ Kd8 34.Qc4 Qb2+ 35.Kh3 Qc3 36.Rc8+ Kd7 37.Rc7+ ½–½ was the pretty dramatic ending to Rahman,Ziaur (2517) - Gaston,Serge (2269) [D44]
Paris-ch op Paris 2002.

Without an engine running it's very hard to know what's going on here, but white isn't as helpless as he sometimes appears in these variations.

Howell is surely struggling after 26.b3. Greet doesn't look to be in all that much trouble to my eyes.
