Jackova,Jana (2403) - Hort, Vlastimil (2512)
Match Prague CZE (1), 09.08.2006
Opening:French Defense:Winawer :Advance variation ECO:C16

The game began with these moves:

1.e4 e6

The French Defense,one of Black's most solid responses to 1.e4.The defence is named after a match played by correspondence between the cities of London and Paris in 1834 (although earlier examples of games with the opening do exist). It has since become one of the most popular defences to 1. e4. Players including Viktor Korchnoi, Wolfgang Uhlmann and Nigel Short have been particularly fond of it. More recently, the defence has featured strongly in the opening repertoire of Evgeny Bareev and Teimour Radjabov (who used it to defeat Garry Kasparov in early 2003, thus becoming the first player who was born since Kasparov took the world championship in 1985 to beat him). The main drawback of playing the French Defense is that the Black queen's bishop is blocked in now by Black's e-pawn. Experts have found creative ways of developing this bishop in their games.

Returning to the game, which continued with these moves:

2.d4 d5 3.Nc3 Bb4

The Winawer variation.This variation, named after Simon Winawer and pioneered by Aron Nimzovich and Mikhail Botvinnik, is one of the main systems in the French. Around the middle of the 20th century, it was the most often seen move after 3. Nc3, but around the 1980s, the Classical Variation began to be revived, and has since become more popular. ...Bb4 pins the c3 knight to the king, leaving the e4 pawn undefended. White has the option of playing a gambit with 4. a3, 4.Bd2 or 4. Nge2 (the Alekhine Gambit), but normally moves his pawn into safety with 4. e5, gaining space and hoping to show that Black's b4 bishop is misplaced.

Jackova now played a move which defines the variation:

4.e5

The advance variation of the Winawer. This is the most frequently played continuation by White closing the center and preventing Hort from playing ...Nf6.

4...b6

Intending to develop the blocked-in bishop by fianchettoeing it. [Analysis:The main line is: 4...c5 5.a3 Bxc3+ A move Bobby Fischer condemmed and said made the Winawer unsound due to the weakness it causes on Black's kingside. 6.bxc3 Ne7 7.Qg4 0-0 8.Bd3 Nbc6 9.Qh5 Ng6 10.Nf3 Qc7 11.Be3 c4 12.Bxg6 fxg6 13.Qg4 Qf7 14.Ng5 Qe8 15.h4 h6 16.Nh3 Ne7 17.Nf4 Qf7]

Returning to the moves in the Jackova-Hort game, for her next move Jackova played:

5.a3

The main continuation forcing Hort to make a decision about the future of his bishop.

5...Bf8

The most often played response to White's last move.

6.f4

Jackova soldifies her center,intending to develop her knight behind this pawn at f3.

Hort creates a decoy,,,suggesting he may fianchetto his king's bishop. However this will not happen. Instead the g-pawn will support the advance of his h-pawn to h5.This move appears to be a theoretical novelty for the position. [Analysis:Usually in this position Black plays the move 6...Ne7 and play continues: 6...Ne7 7.Nf3 Qd7 8.Be3 h5 9.Bf2 Nf5]

The players now played these moves in the game:

7.Nf3 h5
