German "Kader-Challenge" - Blübaum strikes back

by Johannes Fischer
4/7/2021 – With a rating of 2670 Matthias Blübaum is Germany's number one but in round 1 of the "Kader-Challenge" tournament in Magdeburg he surprisingly lost against FM Frederik Svane. However, in round 2 Blübaum bounced back and won against Niclas Huschenbeth, crowning a fine game with a unique mate. The other four games all ended in a draw and with 1.5/2 Frederik Svane remains sole leader. In the women's tournament Jana Schneider leads with 2.0/2. | Photo: Georgios Souleidis (Archive)

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Bb4 5.e3 0-0 6.Bd2 b6 7.cxd5 exd5 8.Bd3 Bd6 9.0-0 Re8 10.Nb5 Bf8 11.Ne5 c5 12.f4 With this move White signals his aggressive intentions. In the game Black does not find an adequate counter. a6 13.Nc3 b5 14.Qf3 c4 15.Bc2 Bb7? This is too slow. It was better to play 15...b4 chase the knight away from c3 to get better control of e4, e.g. 16.Nd1 a5 17.Nf2 Nbd7 18.g4 Bb7 19.g5 Ne4! and after 20.Nxe4 dxe4 21.Bxe4 Bxe4 22.Qxe4 Nxe5 23.fxe5 Qxg5+ Black has nothing to worry about. 16.a3 Nbd7 17.g4 Now White's knight still covers e4 and Black is in trouble. g6 18.Be1 Ne4!? Black decides to give a pawn to avoid worse. 19.Nxe4 dxe4 20.Bxe4 Bxe4 21.Qxe4 Nf6 22.Qc6 White is a healthy pawn up which he converts without much trouble. In the end, Black's desparate attempts to get counterplay result in a picturesque and rare mate.

This allowed Jana Schneider to take the sole lead. However, she first had to turn a drawish rook endgame against Luisa Bashylina in a won rook endgame – and Karsten Müller shows how she managed to do that:

This rook retreat loses valueable time. After 42.Qxc1+ Rxc1+ 43.Kg2 Rc2+ 44.Kg3 Rxb2 45.h4 White's activity gives her a draw, e.g. Rxa2 45...b5 46.a3 b4 47.g5+ Kg7 48.Rd7+ Kg8 49.axb4 Rb3+ 50.Kg2 Rxb4 51.Kg3 a3 52.Ra7= 46.g5+ Kg7 46...Kh5? even loses due to 47.Rd7 Ra3+ 48.Kf4 h6 49.Rh7 Kxh4 50.Rxh6# 47.Rd7+ Kf8 48.Rxb7 a3 49.Rxh7 Ra1 50.Ra7 a2 51.Kg2= 42...b5! Now Black is always too quick. 43.a3 Now 43.Qxc1+ Rxc1+ 44.Kg2 Rc2+ 45.Kg3 Rxb2 46.h4 does not work anymore due to Rxa2 47.g5+ Kg7 48.Rd7+ Kf8 49.Rxh7 b4-+ 43...Qxd1+ 44.Rxd1 Rc2 45.Rb1 Kg5 46.b3 Kxg4?! This greedy capture makes matters much more difficult. The direct 46...b4!? wins quicker, e. g. 47.axb4 a3 48.b5 a2 49.Ra1 Rb2 50.b6 Rb1+ 51.Kg2 Rxa1 52.b7 Rg1+-+ 47.bxa4 bxa4 48.Rg1+ 48.Rb4+ Kh3 49.Kg1 Rg2+ 50.Kf1 Rxh2 51.Rxa4 Ra2 52.Ra7 h5 53.Rg7 Rg2 54.a4 g5 55.a5 h4 56.a6 g4 57.a7 Ra2-+ 48...Kf4 49.h3?! 49.Rg3?! Rb2 50.Rc3 Rb3 51.Rc4+ Kf3-+ 49.Rf1+ is more tenacious, but still loses in the long run after Ke4 50.Rf7 h5 51.h4 Rc3 52.Kh2 Rxa3 53.Ra7 Kf4-+ 49...Ra2 50.Rg4+ Kf3 51.Rxa4 Kg3 The mating threat decides directly. 52.Rg4+ Kxh3 52...Kxh3 53.Rg5 53.Rg1?! Rh2# 53...Rxa3-+ 0–1
