WICC FIDE (8), 15.10.2001

Who was really using computer here !

You have to understand that white lost after 21. Nb4 ? (suggested by Fritz 6 ! Just give it some time) Instead white should play 21. de5 (only move) and after 21..Ba3 ! 22.Qc2 ! =/+ (Only move, otherwise 22..Bb2 and 23..Qa1). Now pawn c3 is protected, so white my want to take on a3. I believe black is better, because of white's weak queen's side. After 21. Nb4 and c5 with Rc8 next white's position is hopeless.

Yes, 17. a3 ?? (suggested by Fritz 6 !) is a terrible move, it is very bad. Remember black has a nice square for his Night on c4. After 0-0-0 pawn a3 will be bishop's target,white's queen side is very week. That was my whole plan later after 0-0-0:Nb6-c4, Qa5 and Ba3. Then white position crashed .

"..can this be used to build a strong flank or not.." - Sorry, I think this does not make sense. I believe he played a3, because he wanted to play 0-0-0. If he wanted to do another flank strategy, he would play 0-0, b4, a4.

You know 17. 0-0 ? is another problem, white's king's side position is weakened too. Black can later try to break by something like g6 and h5 later on, first maybe 0-0-0. I do not think it is good at all. White does not have safe place for his king here. Effects of white's flank strategy, black has
a strong center, white only weaknesses.

There is a better move for white: 17.Qh2!

Idea is to wait and see what black will do. Russians call it "maneuver play" - lavirovanie. White does not have to specify his king's position and he waits till black will declare his first ! Besides that it is a useful move, since it is controlling a center - e5. 17..0-0-0 ? is a mistake, there is a very strong move 18 g5 ! (To activate Bishop on h3-c8) and e5 is now hanging - fight for the center ! White position would be OK.

17. Qc2 !? is possible with the similar idea (maybe later Qb3 and 0-0-0), but I prefer 17. Qh2 since it is controlling e5. h2-b8 would be extremely strong for white. Bd6 is under "X rays"

After 17.. Qc7 (to free the Night Nb6-c4). White can play 18. 0-0-0. So white got 0-0-0 without playing stupid a3. I think black is slightly better, but nothing special.

11. Nf4 Bg6-f7 - This move is obvious (Night moves to f4 and attacks Bishop on g6, I do not want doubled pawns so I escape to f7). My plan is to play e5 now and take over the center, space

12. Nd3 - White is preventing e5 and wants to play e4 by himself.
12.. Bg6 !! - This move could not be suggested by any chess program like suggested by GM Khalifman (I checked with Fritz only), because the machine has coded not to move twice the same piece, it does not think. Idea is to prevent e4 and play e5 by me next. If 13. de5 then 13...Bxd3 and 14..Ne5 ! (Night will be very strong in the center) or even 14...fxe5 holding the strong center. The problem is that in this position there is not so many alternatives. Fritz 6 suggests 12...0-0-0 ? This is a very big mistake. White will play b4, a4 and kill me on the queen-side, while keeping his king safe in the center on king side. Computer can not see that far, he can only calculate variations and his evaluations are very questionable. Maybe I should play 12...e6 ? Wrong, it is blocking the Bishop on f7 ! He can try something like h4. Alekhin teaches that the best method to reply to the flank attack is to take over the center ! So I need to play e5 !

So Mr. Khalifman where is your "...worth noticing that move 12…Bf7-g6 is no way forced by the play of white.." ? It looks like it was forced.

13.e3

I think 13. Bg2 has more sense, controlling e4 and preparing possible e2-e4. At least in that case white does not declare where he is going to move his "e" pawn. 13..e5. 14 e4 Bd6 =

13...e5! = Now the position is equal and black can finish his development. Black finished his "small" maneuver !

Please take a closer look at white's 21. Nb4 (suggested by Fritz). What is the purpose of this move ? After 21... c5 ! white's queenside position opens up and that is the end. 24..Rc8 is obvious, takes c line, x-rays for king and queen, c3 pawn is under attack now. This is a disaster for white now.
