 By GM Kevin Spraggett Kevin's blog (parental advisory)  As promised, here are Viktors notes to his sensational game with Paco from Linares earlier this week. Enjoy!  GM Moskalenko (2524) - GM Vallejo Pons (2706) GM Moskalenko, VGM Vallejo Pons, F Spanish Tch; Rd3 1.b3 d5 2.e3 ( 2.Bb2 Bg4 3.Nf3 Bxf3 is seen often ) 2e5 3.Bb2 Bd6 4.f4!?  Provocative! If Pacos 8th move is as strong as Moskalenko thinks, then this line should not be played except under the most extreme circumstances when White must absolutely play for a win at all costs. Viktor points out that there are good alternatives, such as 4.c4 or 4.Nf3. 4 exf4 5.Bxg7 Qh4+  This has actually been played before on numerous occasions. As well, one can find this theme in some openings with colours reversed. Definitely not for the faint hearted! 6.g3! fxg3 7.Bg2! gxh2+ 8.Kf1  All the games in my database have Black taking on g1, which leads to some advantage for White 8Bg4 !  A powerful novelty that changes the evaluation of this opening variation. 9.Nf3 Qh5 10.Nc3 Ne7 11.Bxh8  The immediate 11Nf5 is quite fine for White: 12.Nb5 Bg3 13.Nbd4 Nh4 14.Ne2 Bxf3 15.Nxg3 Bxg2+ 16.Kf2 Qxd1 17.Raxd1 Bxh1 18.Rxh1 Ng6 19.Bc3 Nc6 20.Rxh2 11Nd7! 12.e4 ( Both 12.Nb5 Bg3 13.Bb2 Nf5 and 12.Ke2 Nf5 look dangerous ) O-O-O 13.Bd4  Almost all of Whites play has been forced up to now. After the game Viktor realized that Black can get the advantage with either 13Nc6! or 13Ng6 14.Bf2 d4! Black is also better in the text 13Rg8 14.Qe2  Last chance for the upper hand is 14Bh3! 15.Bxh3 Qxh3+ 16.Ke1 Rg2 17.Qf1 c5 14Ng6? 15.Qf2! Bh3 ( 15c5 16.Nb5 or 15Nf4 16.Rxh2 ) 16.Bxh3 Nf4 ( 16Qxh3+ 17.Qg2 Qxg2+ 18.Kxg2 c5 19.Kf2 cxd4 20.Nxd5 ) 17.Bxd7+ Kxd7 18.Rxh2 Nh3  Blacks attack is over 19.Nxd5! Rg6 20.e5 Qf5 21.Ne3 Rg1+  One last desperate trick: if 22.Ke2 Nf4 is mate! 22.Nxg1! 1-0 A game worth careful study.
