c3 Sicilian [B22]
Tiviakov - Sutovsky featured the c3 expert's pet 6. Na3 line, and ended up determining the clear winner of the 2008 European Championship.
Kaidanov - Shulman was played in the fifth round of the USA Championship. Yury Shulman dominated the event, scoring three wins in a row with Black against Gulko, Kaidanov, and Becerra!
In Smerdon - Sales Black successfully tries a very rare move against White's 8. Bb3 gambit line:
When White's slight initiative quickly dried up.
Hadzimanolis - Anastasian caught my attention - an Alekhine's Defence quickly turns into a 2. c3 Sicilian! Note that in the game both sides have taken an extra move to reach the theoretical position. Black plays a "bad line" in order to avoid White's gambit play.
Closed Sicilian [B26]
Please allow me to indulge with a couple of short but instructive games of my own...
The Closed Sicilian with Nge2 is not very critical theoretically, but it is still popular at club level. Getz - Vigorito is strategically instructive.
Bb5 Variations [B30 & 51-2]
The "Modern Grand Prix" has become rather popular. I think 4...e6 is the way to go:
See Wang - Vigorito.
In Adams - Cheparinov Adams quickly gets "out of book" to avoid the Bulgarian novelty machine, with 9. h3!?:
White does not have much, but Adams excels in these kinds of simple positions with a space advantage.
Finally, in Hernandez Guerrero-Nakamura, Nakamura wins a nice game with harmonious development in a line that is not terribly theoretical.
Best wishes, David
