AGUILAR CUP
MERALCO SIMUL
EXHIBITION
Pasig City

1 d4 Nf6 2 c4 e6 3 Nc3 d5 4 e3 c6 5 Nf3 Nbd7

MANUAL OF CHESS, "Get the knights into action before both before bishops are developed."

This position has frequently appeared in World Championship Matches; Steinitz vs Chigorin in 1889, Steinitz vs Lasker in 1894, Alekhine vs Bogoljubov in 1934, Euwe vs Alekhine in 1937, Botvinnik vs Euwe in 1948, Bronstein vs Botvinnik in 1951, Karpov vs Kasparov in 1984, Karpov vs Anand in 1998, Kramnik vs Topalov in 2006 and Kramnik vs Anand in 2008. Thus, we can safely conclude that these moves are the best of the best!

n opening theory, this set-up is known as the QUEEN'S GAMBIT DECLINED SEMI-SLAV DEFENCE, which was originated by Alapin a century ago.

THE COMPLETE CHESS PLAYER (on Semi-Slav), "Black renounces the idea of developing his Queen Bishop by Bf5; he intends to fianchetto the bishop later later on."

6 Qc2
MODERN CHESS OPENINGS, "6 Qc2 sidesteps the long variations arising after 6 Bd3, but Black's chances are no worse with accurate response."

This move first appeared in Stoltz vs Berstein in Groningen 1946 and was hence called the STOLTZ VARIATION (ECO D46). In the Man vs Machine in 2003, former World Champion Kasparov used the Stoltz and lost to Deep Junior! Among the Pinoy GMs Bong Villamayor and Darwin Laylo have played with the Stoltz in international tournaments.

6 ... Be7
LOGICAL CHESS, "Moving the bishop only one square may not seem much of a move, but it complies with the first law of rapid development: Get your pieces off the back rank."

This was actually my debut with the Slav and it is encouraging to find out, through the course of my research after this game, that my over-the-board move was also the line played by Deep Junior and Super-GMs Carlsen, Ivanchuk and Vallejo. However, World Champion Anand and former World Champion Topalov preferred the move Bd6.

7 Bd3 dxc4
THE IDEAS BEHIND THE CHESS OPENINGS, "Should Black try ... b5 without the follow-up ... c5, he would simply be saddled with a backward pawn on an open file, while ... dxc4 without ... b5 would merely concede his opponent the better center without adequate compensation.

8 Bxc4

8 ... Nd5?
CHESS FUNDAMENTALS, "Before development has been completed, no piece should be moved more than once, unless it is essential in order to obtain a material advantage or secure freedom of action."

RYBKA recommends 8 ... b5, 8 ... O-O, and 8 ... a6

9 O-O O-O
THE 10 MOST COMMON CHESS MISTAKES, "Nothing is more important than safeguarding your King by castling early, within the first dozen of moves, if possible."

LOGICAL CHESS, "In a cramped position, try to relieve the pressure by forcing exchanges of pieces."

BEST LESSONS OF A CHESS COACH, "Sometimes, the best course of action in chess is to anticipate trouble before it happens."

20 PxB Qf7 21 Rad1 Qf5 22 Qd4 Qf7 23 Be4 Bd7 24 Rd3 Rac8 25 Bh6 c5 26 Qc4 Rfe8 27 Rf3 Qg8 28 Bg5 h5 29 Rg3 Rf8 30 Qd3 Be8 31 BxN PxB 32 Bf6+ Kh7 33 Rg5 Kh6 34 g4 PxP 35 RxP Qe6 36 Rg3

36 ... RxB
THE BLUE BOOK OF CHESS, "When, however, you are about to exchange officers, you must calculate not only their ordinary value, but their peculiar worth in the situation in question; for example, a Rook is generally more valuable than a Knight or a Bishop; but it will happen, that by exchanging a Rook for one of the latter you may greatly improve your game."

However, Rybka recommends Rg8.

37 PxB d4 38 Qd2+ Kh7 39 Qg5 Rc6 40 Rc1 b6 41 h5 QxP 42 PxP+ BxP

THE IMITATION OF CHRIST, "After the great storm, clear and pleasant weather shines through again."

I was surprised when NM Alisangco offered a draw! And though I have a connected passed pawn, I am not sure if my exposed King could survive his Q & R harassment on the open files. Thus, I quickly extended my hand across the board to accept the draw, my first against a titled player!

[1/2-1/2]
