1. e4 e5 $5 {Until this game, my young opponent has been playing a great
tournament, he managed to make four draws with very strong GM's (Erenburg,
Khenkin, Akopian and Kharlov) and scored two victories against weaker
opponents. During my preparation I have noticed that Susanto likes to play
very active chess, with a lot of tactical tricks. I was in a very bad shape
during the Amsterdam open and I had no intention to check my opponent's
tactical skills, that's why I actually opted for a solid opening, instead of
my favourite 1...c5.} 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7.

- good old Ruy-Lopez. This is one of the oldest moves favoured by Botvinnik,
Geller and Smyslov among others, nowadays by Piket. I like to play the same
position with Black but usually I prefer 12...Rd8. The point is Ibragimov
likes 12...Rd8 as well. In that game he probably decided to stick to the old
lines. One recent example of 12...Rd8 is the game Al. Modaihki-F. Eid, match,
Beirut, 2000, which continued:} (12... Rd8 13. d5 c4 14. Nf1 Nb7 15. Bd2 Bd7

failed to press it home in the endgame and only drew...}) 13. Nf1 Nc4 {
Preventing 14.Ne3. As the Ruy-Lopez players know - the f1 Knight is watching
closely the white-squared Bishop of Black - on Bb7 the Knight usually goes to
g3, while if the Bishop remains on the "c8-h3" diagonal the Knight feels very
comfortable on e3 eyeing both d5 and f5 squares.} (13... cxd4 14. cxd4 Rac8 {

attacking plans. First to play g4, Ng3, Kh2, Rg1, Nf5, etc.,(like A-Modaikhi
in the game above...) which is out of question now , since White's Knight is
on g3 in front of the pawn already. By the way this old plan is completely out
of fashion now and I think it is definitely the worst for White. Second - Ng4,
Qf3 trying to force Black to exchange the Knight on g4, and then after hg, Nf5
followed by g3, Kg2, Rh1, etc. About plan three I would like to tell an
amusing story. Back in 1972 in a tournament in Polanitza in Poland I met an
interesting character named Bernard Zuckerman from USA. He told me that he had
discussed a lot of chess positions with Bobby Fischer who was a real legend
then. Bernard asserted that Bobby considered positions with Black pawn chain
of a6-b5-c4, particularly if the queen-side is blocked by White with pawns on
c3-b4-a5, to be leading to winning middle-games for White because of the d4
square for the Knight. I was more than impressed with that since chess was not
so developed then. The attacking scheme for White is almost banal nowadays but
in this game I tried to attack without even touching the queen-side.} 17. f4 $1

beautiful mate:} (50. Qh7+ Kf8 51. Rxf6+ Nf7 52. Be6 Ra7 53. Nc6 Z0 54. Qh6+ {
Ildar disappointed me by resigning instead.  That game was played in round 2
and with it I became a leader in a tournament in which I started as an
absolute outsider being ? 27 in the ranking at the beginning. The quality of
the game as well as the result was an enormous boost for me and as I mentioned
already - Bobby Fischer deserves most of the credit.}) 1-0

connecting rooks and completing the development at the same time. The only
drawback of this move is that it postpones solving the problem of the
a5-knight.} 13. Nbd2 {This also looks natural from the point of view of the

optimal possible way. However, we should take into account the fact that the

play this move, clearing the c5-square for the knight and without fearing the
typical reaction based on b4 and if Nb7 then a4 with chances for White of
maintaining the pressure on both wings.} 14. Nf1 Nb7 {Once the knight will get
to c5, the position will strongly ressemble the Breyer system, with the
significant difference that the bishop was developed on d7 instead of b7. This
obviously favours Black, not only from the point of view of the activity of
the bishop, but also for the possible queen side counterplay based on Rb8 and
b4. The fact that the knights do not have communication between them via d7 is
of less significance, since the king's night has the plan Ne8, g6 and Ng7 at
its disposal, ensuring certain safety on the king side. In the meanwhile,
White has to choose a concrete way to carry out his king side attack.} 15. N3h2

most ambitious continuation. White immediately prevents the enemy knight from
switching to a more favourable route with Nc4. The entire plan looks rather
slow: we are as far as the 13th move and White's queen side is completely
undeveloped. Besides, the c3-square is seriously weakened, which could become
important in case of Black's regrouping with g6, Nh5, Re8, Bf8-g7 and, finally
Nf4. I remember that when I faced this position for the first (and, untill now,
the last) time I had the feeling that Black has an inmense choice, being under
no pressure at all. Other players might have felt in similar way, since the
range of moves played in practice is rather wide. Returning to the problem of
the black knight, its only chance of getting into play is to be transferred to
the remote f7-square.} Rfe8 $6 {This is the kind of waiting move that can be
good in many positions but not entirely adequate here, as we shall see.} ({

O-O 9. h3 Na5 10. Bc2 c5 11. d4 Qc7 12. d5 {At first sight, this might look
like a slight concession. White is supposed to maintain the tension in the
centre for as long as possible, thus keeping in reserve both dxc5 and d5. The
advance of the d-pawn is the customary reaction against the development of the
black light squared bishop to b7, a solution justified by two elements:
1-Black generally threatens to break the centre with ...d5 (eventually after
exchanges on d4) and 2-once the centre has been blocked, the bishop will have
to lose aditional time to find an active diagonal (most likely by returing to
c8). Strictly speaking, blocking the centre without any obvious necessity
looks like making Black a present of 2 whole tempi. However, the text move has
become quite popular lately (no wonder that we have 3 annotated games on it in
this very issue). Here are two possible reasons for it: First of all, one of
the 2 extra-tempi has been spent on the development of the queen to c7.
Generally, this looks like an useful move, connecting rooks, but in many cases
Black feels safer with the queen closer to the own king (more specifically, on
its initial square). Although the problem is not as acute as in case of ...Bb7
answered by d5, there might be situations when Black will feel like returning
with the queen, thus annihilating the advantage of 2 tempi. At the same time,
in closed positions, the significance of time is lower than in open positions.
The second reason is of subjective, psichological nature. In case of the
approved 12.Nbd2, Black has a wide range of continuations at his disposal,
thus making White's preparation more difficult. With other words, by closing
the centre White plays "his" variation, instead of allowing Black do it.} Nc4 {
This looks like a natural continuation. Very often, Black's knight can become
a problem if stuck on a5. With the text move, Black intends to re-direct it
towards a more favourable network of squares, including d7.} 13. b3 {In view

gives Black quite a few choices as well, like taking on d4.} Nc4 {The most
