Syre Memorial op 33th Issy les Moulineaux (2), 14.05.2010

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.cxd5 Nxd5 6.Qa4+ c6 7.e4 With a slightly different move order we got the position from our line, when Black reacts with 5...c6. 7...Nxc3 [The alternative is 7...Nb6 examined in Fressinet,L (2718)-Ruck,R (2555)/Schachbundesliga 2010-11 2010 (15)/1-0] 8.bxc3 0–0







 9.Qa3!? This unnatural move temporarily stops Black's natural play connected with an attack on the white centre by means of c5, ¤c6 etc., but at the same time the white queen appears to be a bit misplaced on a3. [I believe the most natural 9.Be2 c5 10.0–0 Nc6 11.Be3 is White's best option. Here are two thematic examples: 11...Bd7 (11...cxd4 12.cxd4 Bg4 White appears to be ready for this play 13.Rad1 (An interesting idea would have been 13.d5N Ne5 (13...Bxa1 14.dxc6! seems quite promising for White) 14.Rab1²) 13...Qa5 14.Qb3 Bxf3?! (¹14...Qb4 15.Qxb4 Nxb4 16.Rd2²) 15.Bxf3 Qb4 16.Qxb4 Nxb4 17.Rd2 (17.e5!?) 17...b6 18.Rb1± 1–0 Mikhalevski,V (2516)-Koolhoven,M/Vlissingen 1999/EXT 2000 (28)) 12.Qd1! Qa5 13.d5 White's main idea in this kind of structure 13...Ne5 14.Nd2 Ba4?! (¹14...b6 15.Rc1²) 15.Qc1 Nd7 16.Rb1 b5 17.c4 a6 18.f4± and White was clearly better in Gustafsson,J (2603)-Van der Nat,N (2296)/Turin 2006/CBM 113 (30)] 9...Nd7 Another good example here: [9...b6 10.Bg5 c5 11.Rd1 Qc7 12.Be2 e6 13.0–0 Bb7 14.d5! exd5 15.exd5 a6 16.Qb3 and White was better in  Toth,E (2331)-Ernst,M (2177)/Budapest 2006/CBM 115 ext (34).] 10.Bg5 c5 11.Bd3 b6 12.0–0 Bb7 13.Rfe1




[Worthy of consideration would have been 13.d5 ] 13...h6 14.Bd2 Unclear. [14.Bh4 g5 15.Bg3 g4 16.Nh4 e6 17.d5 Ne5÷] 14...e6 15.Rad1 Qe7?! A quite unfortunate square for the black queen. It would be much better playing the normal [15...Qc7 16.h3 Rac8 and Black has a normal game without many problems.] 16.h3 [16.Ba6!?] 16...Rfd8 17.d5! exd5 18.exd5 Qd6 19.c4 b5 20.Qc1² White's passed pawn gives him better prospects. 20...Qf8 21.Ba5 Re8 22.Be2 Nf6 23.cxb5 Nxd5 24.Bc4 Nb6 25.Bxb6 axb6 26.Rd7 Bxf3 27.Rxf7 Rxe1+ 28.Qxe1 Qxf7 29.Bxf7+




 Kxf7 30.gxf3 Rxa2 31.Qe4 Rb2 32.Qb7+ Kf8 33.Qxb6 Bd4 34.Qd6+ Kf7 35.b6 Bxf2+ 36.Kf1 c4 37.Qf4+ Kg8 38.Qxc4+ 1–0

Here the observation of the diagram shows that 1All
Black missiles  are directing towards the White's
Kingside.  2. The Black Knight on f4 is controlling
the h3 and g2 squares.3. Black Bishop is controlling
the e2, g2 and h1 squares. 4) If the Black Knight of
e5-square jumps to g4 square then it will control
h2-square. Think How mating combination can be
formed.?1. First we can bring Black knight on g4
saqure but doing so Black queen lefts undefended
and is attacked by White queen. 2. Black Queen
can be sacrificed by capturing the pawn on h2. 
1...Qxh2+ 2.Kxh2 White King is forced to occupy

Pelikan VariationHere is it very surprising that
Why Black left d5-square so weak. Indeed the
move ...e5 has clear positional advantage. The
d4-Knight is driven avway from its centre position.
And White has leess fredom of movement in the
cnetre and on the kingside. 6.Ndb5 d6 7.Bg5 a6

This move prepares Nc2 followed by a4. White
tries to eliminate the b5-pawn and give the light-
squared bishop an active position on c4. The most
pressing problems for Black are to finish hsi
development, and find better squares for his
pieces, especially his bishops. the e5 pawn is free
from any attack from the white pawns.  11...b4

The White Knight, placed on d5, is cut off from
the remaining light pieces. The g5 Bishop controls
e3- square and the b5-pawn prevents the enemy
bishop from landing on c4, waiting for the move
...a5 stopping Nc2-b4.  Black has one more break
move at its disposal i.e. f7-f5 move to deal with
the d4 pawn defending the Knight on e5. 16.Qd3
