Hamburg GP Final: Duda the defender

A son of the computer era

The third leg of the FIDE Grand Prix is being played in Hamburg, Germany. The 16-player knockout has a €130,000 prize fund, with the series as a whole having an additional prize fund of €280,000 plus two qualifying spots for the 2020 Candidates Tournament. The tournament takes place in the Kehrwieder Haus from November 5^th to 17^th. You can find more info here.

For players like Jan-Krzysztof Duda (b. 1998), dissociating the game of chess from the use of computers is almost impossible. Much has been talked about this subject, with one of the generally accepted consequences of this phenomenon being the fact that players have realized many positions that were considered to be lost in the past can actually be defended — the engines have shown that 'winning won positions' is even harder than people used to think.

Alexander Grischuk (b. 1983), on the other hand, experienced what it was like to face someone like Garry Kasparov in classical chess, when the Beast from Baku would frequently win games simply by showing a forced line that gave a large advantage to either side. Needless to say, Grischuk adapted his style to the new conditions — the Russian has had a 2700+ rating in every official FIDE list since April 2002.

In the rematch game of the final, Duda strangely spent about 18 minutes on move 7, despite the fact that a normal line of the Queen's Gambit Declined was being explored. By the time he played 11.a3, both finalists apparently noticed the position had turned dangerous for White:

A dynamic weapon against the QGD - 5.Bf4

This DVD concentrates on the increasingly popular 5.Bf4 variation of the Queen's Gambit Declined and gives White a dynamic and aggressive weapon against Black's set-up.

Duda's push of the a-pawn had been seen repeatedly in the past, but it is not a move well-liked by the engines (11.♗e5 seems safer). At this point, Grischuk started calculating intensely, spending half an hour on 11...♝Bd7. Also aware of the sharpness of the position, Duda used over an hour of his clock on his next four moves. The sharp sequence went 12.♕xd5 ♜c8 13.e4 ♛b6 14.b4 ♜fd8 15.bxc5 ♝xc5 16.♗e2.

In the diagrammed position, Grischuk continued with 16...♝b5, preventing White from castling. The Russian was clearly in the driver's seat, but Duda kept defending tenaciously. Four moves later, Grischuk rejected a move that would have further complicated matters — by then, Duda had less than ten minutes on his clock.

Power Strategy 1

The first DVD deals with the initial phase of the game, when the all the reigning principles can be crystalized into just one: DEVELOPMENT!

20...♛xe4 is the kind of move one needs to explore carefully — there would probably follow 21.♘d2 ♛xg2 22.♔xe2 ♔♛xh1, when White has two pieces for a rook, but also quite a vulnerable king. Instead of all this, Grischuk simplified into an endgame with 20...♝xf3 21.♕xf3 ♛xc5, an understandable decision given the circumstances, i.e. why take unnecessary risks with little time on the clock when the worst thing that can happen from going into a slightly superior ending is that the score board will remain tied and everything will be decided on Sunday.

Grischuk kept trying to up the pressure, but Duda never stopped finding precise defensive moves. The draw was agreed on move 38.

Sunday's tiebreaks kick off at the usual time.
