Chess The
Restricted Mobility of a Piece Andruet,G (2450) - Spassky,B (2565)
The restricted mobility of a piece. An alarming situation occurs when a piece can be attacked but does not have enough available squares for flight. It is especially dangerous in a situation where the king is placed precariously. 27...Ne5! Here White only expected 27...Rc3, but Black has found a beautiful way of exploiting the restricted mobility of White's king.28.Bb5 Qf3!! 0-1 White resigned because of 29.gxf3 Nexf3+ 30.Kh1 Bh3 with mate to follow.Razuvaev,Y (2490) - Zuckerman,B (2460)
This prevents Nf7, but White should have chosen the following line. 20.Nxe5 Qxe5 21.g4 Nf6 22.e320...Qe7 21.Nce4?! White continues to underestimate the restricted mobility of his queen. It was necessary to continue with the following variation. 21.Kh2 Nf6 22.Kh121...Bf5 22.g4? This loses material, necessary once again was 22.Kh2 Bxe4 23.Bxe4 Nf6 24.Bf3 With a slightly worse but decent position.22...Bxe4 23.Bxe4 Nf6 24.Bg2 Kh8! 25.Ne6 Not 25.Qh4? because of 25...Ng8 26.Kh1 h6 27.Nf3 g5 28.Qh5 Nxf3 29.Bxf3 (29.exf3 Qg7) 29...Kg7 followed by Nf6.25...Ng8 26.Qg5 Rf6! Threatening Rxe6.27.Qh4 g5! 27...g5 was more effective than this variation. 27...Rxe6 28.g5 f3 29.exf3 Nxf3+ 30.Bxf3 Re5
28.Qxg5 28.Nxg5? Rh6-+ 28...Rxe6 29.Qxf4 Ng6 0-1 Zapata,A (2535) - Gavrikov,V (2550)
White was dreaming of an attack. It was necessary to increase the mobility of both rooks first. 33.Ng1 Qc1! 34.Rh4? White should have exchanged the queens - 34.Qd2 Qxd2 35.Nxd2, when Black keeps a considerable advantage after 35...b5.34...Be7 35.Rh5 Bf7 36.Ra5 Bd8 37.Ra3 Qf4 38.Qd2 Too late!38...Bg5! 39.Qe1 Bf6 The unhappiness of the rook on g3 becomes increasingly clear. 40.Kh1 h5! Preventing Rg4.41.e5?! The desperation, although White's position is already lost. 41...dxe5 42.Ne2 Qh6 43.dxe5 Bxe5 44.Nxe5 Rxe5 45.Qd1 Rce8 46.Ng1 Qb6! 47.Nf3 Re2 48.Qd4 Qxd4 49.Nxd4 Rxb2 50.Nf5 g6 51.Raf3 Re1+ 52.Kh2
52...Rbb1! 53.Rg5 53.Nh6+ Kh8! 54.Nxf7+ Kg7 55.Rg5 h4-+ 53...Rf1 54.Rxf1 Rxf1 55.Nd6 Rb1 56.Rc5 Rb6 57.Nc8 Re6 58.Rc7 b5 59.Rb7 Re2 60.Rb6 Re6 61.Rb7 h4 62.Kg1 Be8 63.Kf2 Kf8 64.Nb6 a5 65.Rb8 Ke7 66.Nd5+ Kd6 67.Nf4 Re4 68.Ne2 b4 69.Ke1 0-1 And resigned before I played Kc7.This article is an example of the excellent instructional material that can be found twice a month in the pages of Chess Chronicle, the First Ever Semi-Monthly Online Chess e-zine!
