If you know the theory as Black, it's a great weapon as anyone under 2200 is most unlikely to know the bust (and there is one), that allows white to win easily in the endgame.  Most experts and under are shocked when you grab the second pawn as their knowledge in the line is usually limited to the concept that Black shouldn't be able to get away with this.

Unless one is 2500+ (elo), against strong players you will be giving them easy points.


It's in NIC YB-85.  Every few years someone "discovers" that this line is better than it's reputation. The only problem is, it isn't. In the main line, White's minor pieces are worth more than the rook and pawns.  I'm not saying that the line isn't worth study or doesn't produce interesting chess, just that White is better. 

As White, I would like to try to keep both my bishops.  To that end, Tarrasch's 15.c3 seems like a good move from the tabiya.  Talsma and Boll then advocate 15...f5 16.Be3 (they don't mention 16.Bg5, which is also strong) 16..g6 17.Nd2 Kc8 18.f3 b5 (18...exf3!?)19.Bc2 exf3 20.Nxf3 Re8 "followed by ...Kb7, with equality."  But Black also has to reckon with 19.Bd1, which prevents ...exf3.  E.g. 19...Re8 20.fxe4 fxe4 21.Bc2 and White is better, I opine.

I know I've made some very poor decisions recently, but I can give you my complete assurance that my work will be back to normal. I've still got the greatest enthusiasm and confidence in the mission.

I downloaded the Yearbook 85 games from NIC, and I'm looking over the C80 games right now. I'll be sure to check out the old thread when I'm done. Thanks everyone.

New in Chess Yearbook 85 (brandnew!) has the article titelt "Better than its reputation", Authors: Peter Boll (corr. GM) and Paul Talsma (clubmate of Mr. Boll) - the conclusion is that the "RIGAER" is playable. In the classical endgame the authors propose to exchange the light square bishop and bring the king either via f7 or (and thats new!) via c8 - b7. There are also recommendations against 8.c4 (Euwe) and 8.Bg5 (Berger). This is one of the articles that makes Yearbooks!

You can download the games (of course without comments Grin) from:
http://www.newinchess.com/Yearbook/Default.aspx?PageID=223

I have to edit:
There is of course a treatment in chesspub: Section "e4e5" - December 2003 - As far as I can see the only one (another "to do" for GM Tony K.?  Wink)

I assume Bibs either means New In Chess Yearbook 85 or ChessBase Magazine 85. For both one has to pay.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

Thanks, Bibs. I am quite new to the world of online chess theory. This will seem really obvious but (a) what does CB stand for and (b) is a subscription needed? If the answer to the latter is yes, what was the gist of the article? I assume that the Riga is considered favorable to White or else any Black player content with a draw would play it, but why does it favor White? How would I proceed?

Riga Variation of the Open Ruy Lopez
12/25/07 at 23:24:20

I am just starting to learn to play the Ruy Lopez as White, and I was wondering why the Riga Variation of the Open Defense (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Nxe4 6.d4 exd4) is considered inferior to the main 6...b5 line. The position that arises after 7.Re1 d5 8.Nxd4 Bd6 9.Nxc6 Bxh2+ 10.Kh1 (to avoid perpetual check) 10...Qh4 11.Rxe4+ dxe4 12.Qxd8+ Qxd8 13.Nxd8+ Kxd8 14.Kxh2 seems to favor Black if anyone. After all, he is up two pawns and a rook to two minor pieces. Can someone please enlighten me and explain how to proceed as White?
