Maybe you should say, "Hey Houdini, how do you think this compares to that Ponomariov game?".


The Ponomariov game is a different line. In the line I gave White doesn't play Rg3.

According to Houdini 2.0c, White gets a plus after 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. g4 h6 7. h4 Nc6 8. Rg1 h5 9. gxh5 Nxh5 10. Bg5 Nf6 11. Nxc6 bxc6 12. Qf3 +=.

The Shevy doesn't have anything very like 6 Bg5 or some of the Bc4 lines vs the Nardojf. The Be2/a6 stuff is very sharp and massive theory but isn't so insanely critical.

The place where you do get the ideas thing rather more is when black doesn't play an early a6.

in the book sample he says in the introduction that the Scheveningen is "ideas-based"
I really don't see that much difference with the Najdorf so I suppose it's just sales talk

I'm surprised D'Costa doesn't mention the line
1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. g4 h6 7. h4 Nc6 8. Rg1 h5 9. gxh5 Nxh5 10. Bg5 Nf6 11. Be2 a6 12. Qd2 Bd7 13. O-O-O b5 14. Nxc6 Bxc6 15. Qe3 Qc7 16. Nd5 Bxd5 17. exd5 e5 18. f4! with advantage for White.

Well you can of course play the Nc6 English attack lines Wink But yes that move order commits to that, and to non trivial extra work vs 6 Bc4.

If someone doesn't want to allow a 6.Bg5 Najdorf or the Keres Attack, then he/she can play the Taimanov move order (1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6)! Of course, then you'd have to study 5.Nb5 d6 6.c4 and 6.Bf4.

No if you start with 2...Kc6 & 4...Qc7 before e6. The main drawback is you must tolerate an optimal version of the Qe1 & Qg3 Scheveningen because your queen is already committed to c7.

I do not think so, becuse if you want to play the Scheveningen English Attack, your knight is already on c6, and you cannot play the quick ...b5/b4. I think it works, however, against 6. Be2 and 6. g3. But if you want to play ...Nbd7 against the 6. f4 lines with the Taimanow, again it does not work.

On 22. Bg5, how about 22...Qb6, which I got when I put Fritz on. Then the idea is 23...Rxc3. 23. exf5 Nfd5 24. Nxd5 Nxd5

0-0-0 needs to be replaced with O-O-O.

Strangely, using Fritz again, the line 20...gxh6 21. e5 dxe5 22. fxe5 Qxe5 23. Bf4 Qc5 24. Nb3 Qc6 25. Na5 Qa8 to avoid the idea Rg8 Nxg8 Qxd7 winning the rook on c8.



Doesn't 26.Be5 just win? On 26..Nbd5, Houdini gives 27.Bf3! +-

In your first line w 22..Qb6, 25.Nb3 and a subsequent Bf3 leaves White with a significant, if not winning, advantage. 

Thanks for the O-O-O tip.

Has to be upper case letters for the castling it seems. Thus:

On 20...h6, why not 21. f5 gxf5 22. exf5 e5? Then White must retreat the knight either to b3 or f3. In either case that loses the f5-pawn: 23. Nb3/Nf3 Bxf5.

If White does not advance with 21. f5, then Black should probably continue with ...Qa5 with the idea of ...Rxc3.

So I do not think 20...Rxh6 is forced, and 20...g6 is best.

To use a diagram, type pgn in brackets before the moves and /pgn in brackets after the moves.


I assume you mean 20.h6 g6 21.f5 gxf5?  If so, I would probably play 22.Bg5! here.  The first idea is that 22..Nxe4 loses a piece.  And 22..fxe4 is met by 23.Bxf6 Bxf6 24.Rdf1! and so that if 24.. Bxd4 then 25.Qxd4 winning.  If 22..Nc6 then 23.Bxf6 Bxf6 24.Rg8 Ke7 25.Nxf5 exf5 26.Nd5 wins.  And if Black tries something like 22..Kf8 then 23.exf5 e5 24.Bxf6 Bxf6 25.Ne4 is strong.   

In your line, after 22.exf5 e5 White doesn't have to move the Knight.  He can again play to win with 23.Bg5 exd4 24.Qxd4 Nfd5 (if 24..Nbd5 one nice line is 25.Bxf6 Nxf6 26.Qxf6 Bxf6 27.Rg8 Ke7 29.Nd5#) 25.Bxe7 and I looked briefly at both ..Bxf5 and ..Nxc3 and think White is better.

Back to you.   Wink

ps -- thanks for the tip, but i still can't get the fen to work and the pgn won't recognize 0-0-0 as a move?
