Bouncing back

Chinese grandmaster Wei Yi started the Masters tournament in Prague as the top seed, but had a disastrous start: in round one he lost to Vincent Keymer, in round two he drew against Anish Giri and in round three he collected a second defeat against Aravindh Chithambaram. But then the tide turned, and he won convincingly against David Navara in round four.

In round five, he played with the black pieces against Sam Shankland, who was shipwrecked in the opening.

Wei Yi thus goes into the rest day with a 50% score and two wins in a row.

Before the fifth round, Keymer was the only player in the Masters who had not yet made a single draw. In round five, he played with black against Le Quang Liem and had a good chance of continuing this streak. Out of the opening, he gained the initiative, but was unable to exploit his advantage and found no way through against Le's good defensive efforts.

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.d3 Bc5 6.Bxc6 dxc6 7.Nbd2 Nd7 8.Nc4 0-0 9.Qe2 Re8 10.Bd2 Bd6 11.h4 Peter Leko, coach and second of Vincent Keymer, who provided live commentary in Prague alongside Sagar Shah and Harshit Raja, expressed concern for Black in this position, fearing that White might develop a strong king's attack. However, in the game, this attack proved to be rather harmless. Nf8 12.h5 c5 13.0-0-0 Ne6 14.g4 White, of course, cannot capture the e-pawn: 14.Nfxe5 Bxe5 15.Nxe5 Nd4 and Black wins a piece. 14...f6

15.Rhg1 If White wants to maintain attacking chances, he must sacrifice the g-pawn here. For example: 15.g5 fxg5 16.h6 g6 17.Qe3 g4 18.Nfxe5 Bxe5 19.Nxe5 Nd4 White has regained the pawn, and a double-edged position with chances for both sides has arisen. With the move played in the game, Black can block the position on the kingside and gradually take the initiative. 15...h6 16.Ne3 a5 17.Nf5 a4 18.Rg3 b5 19.Rdg1 Ng5 20.N3h4 Be6 21.Kb1 Qd7 22.c4 Rab8 23.Rc1 Bf7 24.Bxg5 fxg5 25.Ng2 Bf8 26.Ne1 c6 27.Rc2 Red8 28.Kc1 Bd6 29.Nxd6 Qxd6 Black is clearly better. White has no pawn breaks and can only defend. 30.Nf3 Rb7 31.Nd2 Be6 32.Qe3 Rf7 33.Kd1 White is better off leaving the pawn on c5 alone. After 33.cxb5 cxb5 34.Qxc5 Qb8! the position opens up, and White can no longer defend all his weaknesses. For example: 35.Kb1 Rc8 36.Qb4 Bxa2+ and Black regains the pawn with a winning position. 33...Qd7! With this move, Black forces a pawn gain. 34.f3 Qxd3 35.Qxd3 Rxd3 36.Ke2 Bxc4?! With little time left on the clock, Keymer forces the position. More winning chances were offered by 36...Rfd7 for example: 37.b3 bxc4 38.bxc4 Kf7 39.Rg2 and Black has an extra pawn and sustained pressure. 37.Nxc4 bxc4 38.Rxc4 Rfd7 39.Rg2! White defends the difficult position excellently. Black's rooks are very active, but there is no clear path to victory. a3 40.bxa3 Rxa3 41.Rf2! Rb7 42.Rxc5 Rb1 43.Rc2 Ra1 44.Rf1 R1xa2 45.Rxa2 Rxa2+ 46.Kd3 Kf7 47.Rb1 Ra3+ 48.Ke2 Ra7 49.Rb6 Rc7 50.Kd3 Ke6 51.Kc4 Kd6 52.Ra6 Rb7 53.Ra8 Rf7 54.Ra3 ½–½

How to Avoid Mistakes and Boost Your Winning Rate

Doesn’t every chess game get decided by mistakes? Absolutely. But most players never truly comprehend that they are making the same kind of mistakes over and over again.

The top pairing of the round was the game between the two leaders, Praggnanandhaa Rameshbabu and Aravindh Chithambaram. But Aravindh, who played with black, avoided taking too many risks in this game and seemed content with a draw from the start. After a quiet start in a harmless variation of the Berlin Defence, Aravindh lost a pawn, but managed to escape into a drawn endgame.

This doesn't change anything at the top of the table - Praggnanandhaa and Chithambaram are still joint leaders with 3½ out of 5, a full point ahead of four players with 2½ out of 5.

Challengers: Yakubboev sole leader

Things were livelier in the Challengers, as three games ended decisively. And the games were exciting. In the encounter between Nodirbek Yakubboev and Jachym Nemec, for example, there were four queens on the board at some point, and as Yakubboev's queens were more active, he won the game.

64...Qc1? The position is highly complicated, and with only a minute left on the clock, Black overlooks White's threat.
