Grandmaster Chess

One looks in vain for French players in the lineup of the French club Clichy Echecs 92. Two young players Jorden van Foreest and Parham Maghsoodloo have been very successful so far ontop boards, which perhaps supports the thesis that online rapid chess is something that favoursplayers of this generation.

The municipality of Deizisau in the Esslingen district is located a few kilometres southeast of Stuttgart. Anyone who has followed the German Chess League closely in recent years knows that the Schachfreunde Deizisau squad counts withmany young players in itsranks. Bluebaum, Donchenko andKeymerall play for the SF Deizisau.

There are no weakerplayers at all in this final all-play-all phase. A look at the names in the remaining teamsshows how difficult it will be forClichy and Deizisau to keep the lead in the second half of the finals.

Mednyi Vsadnikis made up exclusively of Russian top grandmasters, led by Vladimir Fedoseev; Novy Borhas David Navara and Radoslaw Wojtaszek reinforced by the Indians Harikrishna, Vidit and Sasikiran; and the Poland Husarsare led by Polish starJan-Krzysztof Duda.

Fighting the Grnfeld with g3

The Grnfeld Defence was invented by the famous Austrian Grandmaster Ernst Grnfeld in the early twenties of the last century. One of the first reactions to it came from the great Akiba Rubinstein - the g3 system, fianchettoing the bishop to g2. After that many systems were tried to refute the Grnfeld and nothing really worked. So, Rubinstein's recipe remains a very important positional approach against this dynamic opening.

In contrast to the normalGruenfeldDefence, White e-pawn has reachede4 in two steps. On the other hand, White has the advantage that the black knight cannot exchange comfortably on c3, but must first head for a weaker spot onb6.

6...Nb6 7.h3 0-0 8.Nc3 c5 9.Be3 cxd4 10.Nxd4 Bd7 11.Be2 Nc6 12.0-0

But,of course, it was all correct and so the position is balanced.

12...Rc8 13.Nb3 Ne5 14.Nc5 Bc6 15.Qb3 e6?!

However, this move by Black seems to be a bit slow.

[With 15...Ned7 Black would have better dealt with the knignt on c5.]

16.a4! White has the initiative and gains space.

16...Qc7 17.a5

[Here 17.Nb5 was strong.]

17...Nbd7 18.Nxd7 Nxd7 19.Nb5 Bxb5 20.Qxb5 a6 21.Qb4 Nb8!

Realizing an Advantage

Its a problem every player encounters when he stands better in a game: how to convert his plus into a full point? In this DVD the author answers this difficult question of chess strategy, considering both the psychological aspects of the realisation of an advantage and the technical methods.

Whites initiative has fizzled out again.

22.Rfc1 Nc6 23.Qa3 Qe5 24.Rc5 Qxe4 25.Bf3 Qh4 26.Rac1 Rb8 27.R1c4

In this position, which is actually very acceptable for him, Mamedyarov now makes a bad blunders 27...Nd4??

[Correct was 27...Qd8=]

28.Bg5

The black queen is trapped. 1-0

Hamburg SK in turn beat the strong Novy Bor. Responsible for this was the impressive endgame performance of Julian Kramer against Czech star David Navara on board 4:

Navara,David (2697) - Kramer,Julian (2419)EOC-ch-Final 2021 Online (3.16)

1.c4 c5 2.Nf3 Nf6 3.Nc3 d5 4.cxd5 Nxd5 5.e3 g6 6.Qb3 Nb4 7.Ne4 Qd5 8.Qxd5 Nxd5 9.Nxc5 Nb4 10.Bb5+ N8c6 11.0-0 e5 12.d4 a6 13.Ba4 Bxc5 14.dxc5 Nd3 15.Rd1 e4 16.Nd2 f5 17.Nc4 Nxc5 18.Bxc6+ bxc6

A critical position has been reached. Black, who had not handled the opening well, has regained the pawn with a lot of effort, but is still not in a good position.

19.b3?! But this is not the best move: White allows the return of the black knight to d3 usually not a good omen.

[19.Ne5! and only later b2-b3 would have given Whitequite a largeadvantage.]

19...Nd3! 20.Ba3

And now the white advantage is completely gone.

[Consistent would have been the elimination of the intruder with20.Nb2!]

20...Be6 21.Nd6+ Kd7 22.f3 Bd5 23.fxe4 fxe4 24.Rf1 a5 25.Nf7 Rhe8 26.Ng5 Rh8 27.Rf6 a4 28.b4 Rhf8 29.Nxh7 Rxf6 30.Nxf6+ Ke6 31.Nxd5 Kxd5 32.Rf1 Rb8

Blacks excellent, well-centred position fully compensates forthe sacrificed pawn.

33.Rf6 Ne5 34.b5?

White wants to improve the coordination of his pieces, but it doesnt work.

[Better was 34.Bb2]

34...Nc4!

Crushing Isolated Queen's Pawn Tactics

The aim of this DVD is to offer the viewer tactical exercises that also illustrate the attacking prospects within IQP positions. The content of the DVD emphasizes the importance of understanding this type of pawn structure.

This intermediate move gives Black a nice advantage for obvious reasons.

35.Be7 cxb5 36.Rxg6

After this move the game should be lost for White.

[With 36.Bb4 the black pawns would have been stopped for the time being.]

36...b4

The pawns are rolling!

37.Ra6 b3 38.axb3 axb3 39.Bf6 b2
