Vehi Bach,V (2311)-Vera Siguenas,D (2492) Montcada i Reixac ESP 2016...........21.e5 looks better!

I found this game today, it was play two days ago in swedish elite. It was one of the games that was live broadcasted.

Well, amazing what a google search throws up! A variation named after myself

I remember Eddie Dearing naming the 9.0-0-0 ...14.Qg5 b5!? line after me, but as I point out in my book it should be named after my brother Walter as he lost with it against IM Steve Mannion a few months before I did the same!

There's a lot of interesting analysis here, so I'll have to take a close look at it before commenting - I would say that the  15...b4!? idea came to me at home when I was looking for a good practcial way of avoiding the main lines at the time.

I was analysing without an engine, and was intrigued by the line 16.bxc4 bxc3 17.Qxc3 Qc7 18.h4 d5?!/!? The machine finds the solution to this very quickly, but there are lots of ways for white to go seriously wrong if he hasn't checked it out himself (most engines don't entertain ...d5 here, so white has to find it himself and then do the work on it).

Anyway, I had no idea at the time that Golubev had recommended 15...b4, so I don't mind my name being attached to it:)

Captain Future suggested 16.Na3 Ra4 17.Ka1 not 16.Nd4 nor illegal 16.Ba7. Since I did not see a simple continuation where I was sure that Black is ok, I suggested the 'no sense' variation Bxb5, Qb8, Rfc8 where I am sure that Black is fine.

If you have a good idea how Black should continue after 16. Na3 I would be interested to hear about it.

Before Topalov, (who ironically played Dragon as black at that time) discovered b3 Kb1 was thought as bad since capturing the bpawn as given as very dangeorus. The point of b3 is to capture at a more favorable moment. And to counter hes own invention Topalov invented the Rc8 Nxd4 b5 system.

In the given position I agree that tp2205:s line is best but I belive that black still has some compensaion even in Qb8 line. Unless I missrember I have also faced Ndxb5 (a major difference) in a Interent game a few years ago. There I played Qb8 and after Nd4 Rfc8 I got a crusing attack and won easy.

In another threat http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1307556535/0 a discussion about a new book from David Vigorito starts.
Some pages are online available that exactly comment on this variation:

See pages 59ff which comment on B.Bok-I.Cheparinov.
Congratulations to Roland Lötscher (Swiss_Dragon)! 
Your analysis has made it into the book, page 63!

Now a concrete question. Is 15.b3 really the best line for white? What about just taking the pawn with 15.Ncxb5 Qb8 16.Na3 Ra4 17.Ka1. The white position seems very safe to me.

Kind regards,
Robert

I have got a question on Bok-cheparinov game.Is 19...h5 an only move in this position.Does 19...Ba4 idea work in this case?

@Moderator: You made the right correction at the wrong place. In the game Langer-Schroeder 19.Ka1 was played (you corrected this to 19.Kc1) whereas the move "19.Ka1" in the comment "In a third game (still ongoing) White played the probably more testing move 19.Ka1." should be "19.Kc1".

Moderator's note: (double) corrected again. Thanks.
