Sigeman&Co: Van Foreest extends lead, Keymer beats Nihal Sarin

by André Schulz
9/28/2021 – In round 5 of the TePe Sigeman&Co tournament in Malmö the two young Grandmasters Vincent Keymer and Nihal Sarin had to play against each other. Nihal Sarin outplayed Keymer but then blundered his advantage away and even lost. Jorden van Foreest won against Etienne Bacrot and now leads with 4.0/5. Nils Grandelius and Nigel Short follow with 3.0/5 each. | Photos: Lars OA Hedlund

Three of the world's best juniors born in 2004 play in the TePe Sigeman&Co tournament: Nihal Sarin, Vincent Keymer and Jonas Bjerre. Other players of this age group are Nodirbek Abdusattorov and Javokhir Sindarov from Uzbekistan, and of course the Indian Praggnanandhaa. Nihal and Praggnanandhaa in particular made a lot of headlines with their successes before Corona brought over-the-board tournaments to a halt. Unlike the two Indians, Vincent Keymer is still going to school and wants to take his Abitur before before trying life as a chess professional.

Recently, at the Hou Yifan Online Challenge, Keymer got the better of Praggnanandhaa, and in round five of the Sigeman&Co tournament he clashed with Nihal Sarin.

Keeping an eye on the opponent

Vincent Keymer had White and after 1.d4 Nihal Sarin opted for the Bogo-Indian, and after the opening gradually outplayed Keymer. But when he was close to winning the Indian miscalculated and let Keymer back into the game. Eventually a tricky endgame was on the board that required precise calculation. Keymer was up to the task and managed to win the game.

1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Bb7 5.Bg2 Bb4+ 6.Bd2 c5 7.d5 exd5 8.Nh4 0-0 9.0-0 Bxd2 10.Qxd2 Ne4 11.Qc2 Re8 12.Nc3 Nxc3 13.bxc3 d6 14.Rad1 Nd7 15.Nf5 Nf6 16.cxd5 Bc8 17.Rfe1 Bxf5 18.Qxf5 b5 19.e4 Nd7 20.Rb1 Rb8 21.Bf1 b4 22.c4 g6 23.Qh3 Nb6 24.Rb3 Qf6 25.Qg4 Re7 26.Qd1 Rbe8 27.Rbe3 a5 28.Kg2 Black is clearly better: he can create a passed pawn on the queenside and the black knight is much better than the white bishop. Qb2? Not a good idea. Immediately 28...a4!? was probably better. 29.R1e2?! More precise is 29.e5 which stops Black's queen from retreating and leads to complications. Rxe5 29...Qxa2 30.R3e2 Qa3 31.exd6 31.Re3 Rxe5 31...Rxe2 32.Rxe2= 30.R1e2 Qd4 31.Rd2 Rxe3 32.Rxd4 Re1 33.Qc2 cxd4 with chances for both sides. 29...Qd4 30.Rd2 Qg7 The queen safely returned home. 31.Bd3 a4 32.Qc2 a3 33.Rde2 Qd4 34.h4 Nd7 35.Rd2 Qg7 36.Rde2 White has no counterplay and can do nothing but wait. Qd4 37.Rd2 Qg7 38.Rde2 Ne5 39.Re1 h5 40.R3e2 Qf6 Time pressure is over. 41.Re3 Ng4 42.R3e2 Kg7 Black is clearly better but fails to find a convincing winning plan. 43.Rd2 Rb8 44.f3 Nh6 45.Rde2 Rbe8 46.Qb3 g5? Allowing White counterplay. 47.hxg5 Qxg5 48.f4 Qf6 49.Rh1 White is back in the game. Qd4 49...Qg6 50.e5 Nf5 51.Bxf5 Qxf5 52.Qf3= 50.Rxh5 f5 51.Rg5+ 51.e5!? dxe5 52.Bxf5 51...Kf8? Correct was 51...Kf6 e.g. 52.Bc2 Rxe4 53.Bxe4 Rxe4 54.Qf3 Qxc4 55.Rxf5+ Nxf5 56.Qxe4 Qxe4+ 57.Rxe4 Nd4 and the queenside pawns decide the game. 52.Bc2? After 52.e5 dxe5 53.Bxf5 exf4 54.Be6 White should hold. 52...Rxe4 53.Bxe4 Rxe4 54.Qf3 Rxe2+? 54...Qxc4-+ 55.Qxe2 Qe4+? Black relies on his queenside pawns, but White is just in time to stop them. Better was 55...Qb2 56.Kf3 Qxe2+ 56...Qb1= 57.Kxe2 b3 58.Rh5 58.axb3 a2-+ 58...b2 59.Rh1 with a complicated position in which White has slightly better chances. 56.Qxe4 fxe4 57.Rg6 Nf7 58.Re6 b3 59.Rxe4 b2 60.Re1 Nh6 61.g4 To stop the knight from coming to f5. But 61.Kf3 was also possible: Nf5 62.Rb1 Nd4+ 63.Ke4 Nc2 64.Kd3 Nb4+ 65.Kc3 Nxa2+ 66.Kb3 Nc1+ 67.Kxa3 Ne2 68.Kxb2 Nxg3 69.Re1 and White wins. 61...Nxg4 62.Kf3 Nh6 63.Ke4 Kf7 64.Kd3 Nf5 65.Kc2 Kf6 66.Kb1 Ng3 67.Re3 Nf1 68.Rxa3 Nd2+ 69.Kxb2 Nxc4+ 70.Kb3 Ne3 A last try. 70...Nxa3 71.Kxa3 Kf5 72.Kb3 Kxf4 73.a4+- 71.Ra7 Nxd5 72.a4 Nxf4 73.a5 Ke5 74.a6 Kd4 75.Rb7 1–0
