Tips from grandmaster praxis

French Grandmaster Thal Abergel finished second in the recently held Championnat de Paris tournament. He scored seven points in nine rounds. Out of his six wins in the tournament, he rates the one against IM Christophe Sochaki as his best.

Abergel spent close to an hour on the eve of this match preparing against the 4.d4 variation of the Sicilian. He prepared this line knowing his opponent preferred capturing the d4 pawn with the queen instead of the knight.

It paid off as Abergel won in 59 moves. Here’s his game analysis:

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Qxd4 I had noticed that Qxd4 is his favourite continuation in the open Sicilian. a6 5.h3 This move seems a bit strange to me and he played it at least three times. With the help of my friend GM Andrei Shchekachev, I noticed that I can let the white queen remain on d4. Otherwise in most of the lines, it will retreat and follow it up by Nd4. Instead I went for a new kind of formation. Nf6 6.c4 e6 7.Nc3 Nbd7 I tried to play a hedgehog structure with my opponent’s queen on d4. 8.g4!? A very aggressive move. Next is g5. I don’t really don’t want to bring my night to h5. Qc7 9.g5 Ne5 10.Nh2!? Interesting but a weird place. Nc6 11.Qe3 Nd7 12.b3 I am not sure how good this move is but black the fact is that white enters into very deep complications . b5‼ There are two choices for white; take the pawn and play a very complicated series of moves or avoid complications by not taking the pawn which is worse. 13.Bb2?! Wrong choice. b4 14.Nd1 e5 Blocking the second bishop and securing the c5 square for my knight. 15.Qd2 Nc5 16.Bg2 Be7 17.h4 h6!? I thought I had to play for a bigger advantage quickly before the knights on d1 and h2 regroup. 18.Ne3 hxg5 19.Nd5 Qd8 20.Nxe7 Qxe7 21.hxg5 Bb7 I understood that in the long term the white king is weaker than black’s. My last move guarantees a very safe place for my king on the queen side. 22.0-0-0 0-0-0 23.Ng4 Rxh1 24.Rxh1 Ne6! 25.Rh7 Rg8 26.g6 fxg6 27.Bh3?! 27.Ne3! Keeps control of the centre and gives protection for the white king. 27...Kb8 28.Nh6 Rf8 29.Bxe6 Qxe6 30.Rxg7 White took the pawn back but at the price of a very weak king. Ka8 31.Qe3 Qf6 32.Rd7?

I have to get passed pawns. 40.f3 Rh2 41.Rxg6 Rxa2 42.f4 Rb2 43.f5 Rxb3+ 44.Kxd4 Rf3 45.c5 dxc5+ 46.Kxc5 Ka7 47.Kxb4 Bxe4 48.Rf6 Bb7 49.Rf7 Kb6 50.Rf8 a5+ 51.Kc4 a4! 52.f6 a3 53.Rd8 a2 54.Rd1 Be4 55.f7 Rxf7 56.Kb3 Rf2 56...Bd5+?? 57.Kb2 Kc5 58.Ra1 This position is a theoretical draw. 57.Rd6+ Kb5 58.Rd1 Bc2+ 59.Ka3 The last trap.

The element of surprise

According to Abergel, preparing opponent-specific variations is one of the prime aspects of training before and during tournaments.

"Surprise is an important element in chess. I try not to stick to a particular line, so as to make it very difficult for my opponent to prepare."

"If an opponent plays a weird line then you should go for it and exploit it to your advantage. You can also prepare a long variation lasting 25 to 30 moves in order to trap an opponent."

Abergel contends the surprise element gives you a confidence boost which is already a good start.

‘Psychological preparation is the key’

Abergel says 80 percent of the tournament preparation is about psychology while 20 percent is about chess technique. This applies to everyone, from a club player to a grandmaster.

Thal Abergel“There are different methods of preparing yourself psychologically. I use a kind of auto-hypnosis technique by which I convince myself that I am very strong and efficient.

In the second half of this tournament, I told myself that no matter who my opponent is, after 20 moves he will have big problems. This gave me a lot of confidence going into a game.”

“As a chess coach I have noticed that 90 percent of my students made big progress by focusing attention on the psychological aspect.”

For the chess preparation part, Abergel recommends devoting a majority of the time to studying tactics. 

“I spent a lot of time studying tactics during my growth in chess. Even now, before a match, I solve a couple of tactical problems as a sort of warm-up. It makes your game sharper,” he says. 

Training with chess software

According to Abergel, in this age, using chess software for training is essential for every competitor. 

"I use ChessBase a lot. Currently, I train with ChessBase 15. It’s a big plus because while working on new openings and new positions. One can easily check the way strong players follow a particular line and the plans they make.

"It also allows you to know the statistics of the openings your next opponents have played. This makes preparing against them easier. Furthermore, an essential function of the ChessBase software is that it allows you to create your own databases and embed games into it", he says.
