Supporting chess professionals

For its premium members, the Association of Chess Professionals, together with ChessBase, organized two tournaments in knockout format, one open and one for women. Both tournaments were held on the PlayChess server on July 23-28.

With the tournament, the ACP members obtained an opportunity to play and be financially supported. Many chess professionals currently have no sources of income at all because of the Corona lockdown. 

A knockout system was used in both tournaments. In the Open, 16 players took part, while 12 players participated in the Women's. Some well-known players registered to participate — Pavel Eljanov, Nikita Vitiugov, Gawain Jones, Antoaneta Stefanova, Pia Cramling, among others. Each elimination round consisted of four rapid chess games with a time control of 10 minutes for the game plus 5-second increments. 

The total prize fund was 2,600 Euro and at least 16,800 ducats. (Ducats can be used in the ChessBase Shop and to use the Engine Cloud).

In the open tournament, Alexander Donchenko confirmed his excellent form and advanced to the final with victories over Anatoli Vaisser, Aleksandr Rakhmanov, Daniel Fridman and Nikita Vitiugov. Then, the young German grandmaster was paired up against Gawain Jones in the final. Donchenko, who comes from winning an over-the-board event in the Czech Republic, won two games and drew the rest to take the title.

24...a6 25.Bc3 Qb6 26.Bd4 [Driving the black queen to her desired square.]

Donchenko also won the fourth game:

 

From this rather harmless-looking position, White obtained a decisive advantage in a few moves.

19.Rbd1 Rd8 [19...e5 20.Nxd6 Rd8 21.Nxc8 Raxc8 22.Qc3 with an extra pawn.]

20.Rfe1! Rd7 21.e4 fxe4 22.Rxe4 e5 23.Rh4 [A very uncomfortable rook swing for Black.]

23...h5 [23...N8a7 24.Qh6+ Kg8 25.Rxd6 Rxd6 26.Nxd6 Rd8 27.Ng5 Rxd6 28.Bd5+ is terrible.]

24.Ng5 [24.Bh3 Rd8 25.Ng5 was also very strong.]

27.Re1 [Threatening Rxd4.]

28...Re7 29.fxe5 [29.f5!]

29...dxe5

 

30.Rf1 [Actually lets black off the hook.]

30...Qc6 [30...Qd6 with potential for consolidation. 31.g4!? (31.Ne4 Bxe4 32.Rxe4 Nd7 is not good for white.) 31...Qc6 is now better, because the knight cannot go to e4. 32.Nf3 Rf8 33.Bg2 Ref7 34.gxh5 Rf5 White has the better prospects, but it’s not over yet.]

31.Ne4 [Clears the diagonal for the queen and threatens Bg2. It’s over.]

31...Rf7 32.Rxf7+ Kxf7 33.Bg2 Kg8 34.Qg5 Rf8 35.Rxh5 Bc8 36.Rh6 Bf5 37.g4 Kg7 38.gxf5 [Everything wins. 38.Qe7+ Rf7 39.Rh7+ Kxh7 40.Qxf7+ Kh6 41.Qf8+ Kh7 42.Ng5#]

38...Rxf5 39.Qh4 Nc8 40.Rh7+ Kg8 41.Rh8+ Kf7 42.Qh7+ Ke6 43.Qxg6+ 1–0
