After a couple of theoretical DVDs, it is time now to present a product which I believe I can do better- a study course on the general understanding of the game. The idea of my new DVD is to teach how to use better our line pieces (queens, rooks and bishops). It also offers tips how to seize the important diagonals and files on which these pieces are operating best. You probably all remember the famous game Karpov-Unzicker (it is in the DVD as well), and the following game saw a similar approach, this time thanks to the useful help of the knight.

Although Fritz 9 (the strongest engine by the time that the game was played) evaluated that this position is in favour of Black (!) I am inclined to think that White is strategically winning. My plan is simple-to put the knight on b6, after which he has or to stay at one place when I exchange on b4 and later win this pawn, or exchange on c3, after which I double the rooks on the b file under the knight protection and penetrate with the them in the proper moment.25...Rb5?! This loses a couple of tempos. Better is:[25...Rf7 26.Nb6 bxc3 27.bxc3 Qh4 28.Qe2 h5 29.Rab1 Rbf8 (29...Rfb7 30.Rb3 (30.Rb2 Bh6 31.Reb1) 30...g5) 30.Rf1, although here too, White conducts easily his plan.] 26.Qe2 Bf6 27.Reb1 Rb7 28.Nb6 bxc3 29.bxc3 Rbf7 30.Rf1 Bh4 31.g3 Bg5 32.Nc4 Qd7 [32...Rb7 33.Rab1] 33.Rab1 Bd8 34.Rb8 h5“ 35.Kg2?! I started to feel quite nervous in his own time trouble, and missed the clear win: [35.Rfb1!

Now it is under control again, though Fritz evaluates for quite a long time that it is slightly better for Black (!).42...Kg7 [42...d5 43.Kf3 b3 44.Ke2 b2 45.Na3 c4 46.dxc4 Bd6 47.Nb1 dxe4 48.Ke3+–] 43.a6 b3 44.Kf3 Kf6 [44...b2 45.Na3 Ba7 (45...c4 only chance 46.dxc4 Ba7 47.Ke2 Bc5 48.Nb1 Kf7 49.Kd3 Bxf2 50.Na3 Ke7 51.Kc2 Kd7 52.Nb5 Kc6 53.a7 Kb7 54.Nxd6+ Kxa7±) 46.c4+–] 45.Ke2 b2 46.Na3 Ke7 [46...d5 47.c4] 47.Kd2 Kd7 48.Kc2 Kc6 49.Nc4 d5
