Eric just called me, apparently he managed to play Bxh7+ again this morning, against a youngster who should have been well prepared! He mated his opponent quickly, although this time he preferred Rd1.
We will no doubt see the rest of the game in the next update! Smiley

This novelty has now been voted the eighth most-important of Informant 105!


However, it seems that the credit should really go to Klaus Kögler, who apparently had already played this in a correspondence game.

Kögler - Matheis, ICCF 2007

1. d4 d5 2. Bf4 Nf6 3. e3 e6 4. Nf3 c5 5. c3 Nc6 6. Nbd2 Bd6 7. Bg3 O-O 8. Bd3
Qe7 9. Ne5 Nd7 10. Nxd7 Bxd7 11. Bxd6 Qxd6 12. dxc5 Qxc5 13. Bxh7+ Kxh7 14.
Qh5+ Kg8 15. Ne4 Qc4 16. Ng5 Rfd8 17. Qxf7+ Kh8 18. Qh5+ Kg8 19. Rd1 Qb5 20. f4
d4 21. Qf7+ Kh8 22. e4 1-0

With this move order, I think 9.Nxc6 is best. Black is not ready to hit back with ...e5, so instead he has to defend the c6 pawn with ...Bb7.

9.Nxc6 bxc6 10.Qa4 Bb7 11.Bxd6 Qxd6 12.Nb3 with a slight edge for White.



I've analyzed this line with Fritz 11 and it judges the position as =, not slightly better for White.

Also, in the Nxd7, Bxh7+ line, is 10...Qxd7 still thought to be ok for Black?

The variation played vs Dmitry SVETUSHKIN is not a novelty, it was played first by Prié versus Thomas Bonn (Rochefort Tournament)

I think Black can just avoid this line with the move-order 1 d4 d5 2 Bf4 Nf6 3 e3 e6 4 Nd2 c5 5 c3 Nc6 6 Ngf3 Bd6 7 Bg3 Qe7 8 Ne5 Nd7. The Nxd7 and Bxh7 idea obviously doesn't work here because Black hasn't castled. If White plays something like 9 f4, 9 Ndf3, or 9 Nxc6 bxc6, Black can safely castle because the Nxd7 and Bxh7 idea has been avoided.

With this move order, I think 9.Nxc6 is best. Black is not ready to hit back with ...e5, so instead he has to defend the c6 pawn with ...Bb7.

In the position considered in games 10-14, i.e. after the moves:

1.d4 d5 2.Nf3 e6 3.Bf4 Bd6 4.Bg3 Nf6 5.e3 O-O 6.Nbd2 c5 7.c3 Nc6 8.Bd3 Qe7 9.Ne5 Nd7

there is an interesting alternative for White that isn't mentioned.

White can play 10.Nxd7.

The point is that after the natural 10...Bxd7 White has a surprising resource.

11.Bxd6 Qxd6 12.dxc5 Qxc5 13.Bxh7+! Kxh7 14.Qh5+ Kg8 15.Ne4! gaining tempo by hitting the Black queen. Black's defensive problems are increased because the bishop on d7 may be vulnerable after a future Qxf7. Analysing this with Fritz suggests White has a clear, maybe winning,  advantage.

Unfortunately Black can avoid this by 10...Qxd7. Then the sacrifice is still good enough for a draw, but no more.

Anyway, there's a pretty good chance of Black falling into the trap.

No, I will continue to ask you to stop criticizing "Win With the London System" unfairly!

i tried to study deeper the position after 9...Nd7 10.Nxd7 Bxd7 11.Bxd6 Qxd6 12.dxc5 and i analysed 12...Qc7!? which seems good! After say 13.O-O (13.b4 a5 with a combination of b6 because now the c3 pawn is unprotected) 13...Ne5 14.Nb3 Ba4 with Nd7 and Black gets his pawn back!

What about 13 Qc2, say, defending the bishop with gain of tempo?

I haven't seen this update but i remember over a year ago when i was analysing Cox's lines, my PC (running Deep Junior 10) "saw" this line very quickly! That's why in a game of mine i played 9...Bxe5 10.dxe5 Nd7 and after 11.f4
(11.Nf3 f6 12.exf6 Nxf6 13.Ne5 Bd7! with the idea after 14.O-O Nxe5 15.Bxe5 Bc6! and Nd7-e5 next)
11...f6 12.Nf3 and i played 12...g6 with the idea Qg7. I remember that my opponent played the interesting 13.Bh4 Qg7 14.exf6 Nxf6 when i played c4-b5-a5 etc. After the game (which i won) my PC liked White very much! So, i tried to study deeper the position after 9...Nd7 10.Nxd7 Bxd7 11.Bxd6 Qxd6 12.dxc5 and i analysed 12...Qc7!? which seems good! After say 13.O-O (13.b4 a5 with a combination of b6 because now the c3 pawn is unprotected) 13...Ne5 14.Nb3 Ba4 with Nd7 and Black gets his pawn back!

The game is on Eric's latest update, and he appears to agree that your Rd1 is stronger. Wink

It seems I wasn't the only one confused. TWIC 756 has the same incomplete game score, but recorded as a win for White.

Edit - I've now seen the complete game.  I can understand why your nerves couldn't stand the tension - the last part of the game is wild.

That's a pity, because it deserves to go down as a win.  You have to do that sort of thing, though.


Well, it wasn't at all easy to win at the end ... and our nerves just couldn't stand the tension any more! Roll Eyes

I found a game score at the French Federation's website, but it says it's a draw? Is that right? - the final position looks good for White.  Sad


Yes, but a draw won the match for us, so the Montpellier captain (our own Glenn Flear) asked Eric to take the repetition when he had an extra exchange (the end of the game is missing from the FFE site).

When I analysed this, I (and my friend Fritz) thought that it was better for White to play Rd1 (when the queen is on h5) instead of playing h2-h4 (with the queen on f7).  I think both lines win, but Rd1 seemed clearer. It's hard to find anything useful for Black to do in this position.


You might be right, I can't even find one decent move for Black!
