The games start at 14:00 local time (21:00 CET) and will be commented live on Chessdom with GM Dimitrov.

The games of Hammer are usually the ones in this tournament that are most entertaining and full of combativity. Let's hope he'll keep the tradition today.

1.d4 g6 2.c4 Bg7 3.e4 d6 King's Fianchetto is a popular opening at the open tournaments and quite rare at GM level.

4.Nc3 e5 4...Nf6 could have transposed into King's Indian Defense.

5.Be3 ( The main moves are 5.Nf3 or the ambitious 5.dxe5 dxe5 6.Qxd8+ Kxd8 7.f4)

5... exd4 6.Bxd4 Nf6 Considered to be the best reply against 5,Be3. Black can gain temps by Nb8-c6.

7.f3 O-O 8.Nge2 a6 (8... Nc6 9.Be3 Ne5 10.Nf4 Re8 11.Qd2 would be the standard continuation but very interesting is the alternative 8...Bh6 trying to exploit the weakened dark squares.)

9.Qd2 Nc6 10.Be3 Ne5 11.Nf4 c6 12.b3 ( Defends 'c4' in case of g6-g5 but weakens further the dark squares. Deserves attention the aggressive 12.h4 b5 13.O-O-O)

12... b5 13.cxb5 This is a serious positional concession. Black may open up the center while White King is still there.

13... axb5 14.Rc1 Re8 15.Be2 ( Now Mamedov may try to take over the initiative by 15.Be2 d5 16.exd5 g5 - sample line 17.Nd3 Nxd3+ 18.Bxd3 b4 19.Ne2 Nxd5 20.Bxg5 f6 21.Bh4 Ne3)

15... d5 16.O-O Admission of erroneous opening strategy.

16... dxe4 17.fxe4 Qe7 18.Nd3 Nxd3 19.Bxd3 Ng4 Mamedov has full control over the center while White has it difficult to coordinate his pieces.

20.Kh1 Rd8 21.Bf4 (21.Bg5 Qd6)

21... b4 22.Na4 Ba6 23.Nc5 Bxd3 24.Nxd3 White is losing a pawn and still has trouble getting off the pin.

24... Qxe4 25.Nc5 ( The best chance was 25.Rce1 hoping for 25... Qxd3 26.Re8+ Bf8 27.Qxd3 Nf2+ 28.Rxf2 Rxd3 29.Re1)

25... Rxd2 26.Nxe4 Re2 27.Rc4 f5 Mamedov develops his initiative very well.

28.Ng3 Rexa2 29.h3 Nf2+ 30.Kh2 Nd3 31.Bd6 Rb2 White is 2 pawns down and under attack.

32.Rd1 Ne5 ( The simple 32... Rxb3 was sufficient for the win.)

33.Rc5 Nf3+ 34.Kh1 Rd2 35.Rcc1 (35.Rxd2 Ra1+)

35... Rxd1+ 36.Rxd1 Nd4 37.Bxb4 Nxb3 38.Rd3 Hammer was able to hold the attack but the endgame is hopeless

38... c5 39.Rxb3 Rb8 40.Ne2 Rxb4 41.Rd3 Rb1+ and White resigned (41... Rb1+ 42.Kh2 Be5+ 43.g3 Rb2 44.Re3 Bd4) 0-1
