Prague Masters 2023 R4: Bogdan-Daniel breaks the Berlin, joins the lead with Keymer

by Shahid Ahmed - 25/06/2023

Bogdan-Daniel Deac (ROU) defeated Ray Robson (USA) to join the lead with Vincent Keymer (GER) 2.5/4 at 5th Prague International Chess Festival 2023 Masters. Deac capitalized on his opportunity when his opponent made a positional mistake, allowing his queen to intrude on Black's kingside easily. Keymer had a 100-move marathon draw against the Czech Republic no.1, David Navara. Pentala Harikrishna had another hard-fought draw against the legendary, Boris Gelfand (ISR). He is still a half point behind the leaders along with five more players at 2/4 each. Round 5 for Masters and Challengers, and Round 4 Open starts today at 3 p.m. local time, 6:30 p.m. IST.

Masters: Deac - Robson: 1-0

Romania no.3, GM Bogdan-Daniel Deac (2693) faced GM Ray Robson (USA, 2689) in only one rated game which ended in a draw. Yesterday, the Romanian won their second encounter.

Position after 25.Qxd3

White is aiming to bring his queen to the kingside via f5-e6. 25...Rc8 facilitated White's idea 26.Qf5 Nd6 too little too late 27.Qe6+ Nf7 28.Ng6 it was just a matter of time for Black's position to fall.

Hao - Haik

Position after 27...Nb6

GM Hao Wang (CHN, 2722) could have won his first-ever rated game against GM Haik Martirosyan (ARM, 2685) much earlier, if he played 28.Nd6 right away. Delaying it, denied him a quicker victory. 28.g3 Kd7 29.Nc5+ Ke8 30.Ne4 Kd7 31.Nd6 it did not remain as effective as it could have been. 31...f6 32.exf6 Kxd6 33.fxe7 Kxe7 allowed Black to get back in the game.

Position after 39.Bc2

It was not easy to spot how Black can still save the game after 39.Bc2. However, 39...exf4 40.gxf4 only helped White as he got rid of his double pawns and the threat of a potential passed pawn on the e-file also got eliminated at the same time.

Challengers: Gledura - Vykouk: 1-0

The only rated game between GM Benjamin Gledura (HUN, 2645) and IM Jan Vykouk (CZE, 2467) occurred about seven years ago which ended in a draw.

Position after 40.Rxc5

White wants to roll the d-pawn down the board and promote it. However, his sole weakness is his king. That's what Black needed to exploit 40...Raa1. Instead, 40...Nf5?? allowed White to gain decisive advantage 41.d6 Nh6 42.Bf2 Rb8 43.d7 Rd8 44.Rc8 Nf7 45.Bg3 and it's over.
