I think Mas problem in this game start here. He probably should weaken black kingside with 13.h6 first before castling. 13...g6 (13...g5 14.Nxg5 Bxg5 15.Qh5+) 14.0–0 13...0–0 14.Ne5 Now 14.h6?? is no more dangerous because white's f4 bishop is enprise 14...Bxc3 15.bxc3 Rxf4 14...Bxe5 15.Bxe5 Nxe5 16.Qxe5 Nxd3 17.cxd3 Rf5 18.Qh2 White can't defend his weak h5 pawn with 18.Qe2? because 18...Qh4 19.g4 Rg5 20.f3 Qxh5 18...Bd7 19.Rae1 Qf6 20.h6 20.Qd6 Rf8 21.Qxd7 Rxf2 22.Rxf2 (22.Qxe6+ Qxe6 23.Rxe6 Rxf1+) 22...Qxf2+ 23.Kh2 Qh4+ 24.Kg1 Qxe1+ 25.Kh2 Qh4+ 26.Kg1 Qf2+ 27.Kh2 Qf7 20...Qxh6 21.Qxh6 gxh6 22.d4?!
I think white d pawn should remain on d3 because on d4 it look more vulnarable against black's rook attack for eg. Rf4. 22.d4 also prevent white's knight from using d4 as an outpost with Ne2-Nd4. 22.f4!? try to hold black's centre pawn probably a better try. 22...Kf7 23.Re3 h5 24.Rfe1 Rg8 25.f3 Better is 25.Ne2 h4 26.Rh3 25...h4 26.Kh2 Rfg5 27.R1e2 Ke7 28.Re5 Kd6 29.Rxg5 Rxg5 30.Kh3 Rf5 31.Rd2 Mas has to defend his problematic an isolated d4 pawn, if not 31.Kxh4 Rf4+ 32.Kg5 Rxd4 33.Kh6 Rh4+ 34.Kg5 Rh2 Black d5 pawn will advance 31...Rf4 32.Kh2 Rf8 33.Re2?!The position is already difficult and Voigt continue brilliantly with 33...h3! 34.Kxh3 e5+ 35.Kg3 exd4 36.Nd1 Bf5 37.Nf2 Mas try to create a blockade at d3 but to no avail. Black's rook, bishop and king is all active and ready to penetreate white's position. 37...Rg8+ 38.Kf4 Bb1 39.g4 If 39.a3 Black can play safe with 39...Rf8+ (Or he can play "my cold blooded friend" - Fritz 11 suggestion 39...Rxg2!? 40.Ne4+ dxe4 41.Rxg2 e3 42.Rh2 Kd5 43.b3 Black connected e-d passed pawn is too much to handle! 43...Bg6 ) 40.Kg3 Rc8 39...Rf8+ 40.Kg3 Bxa2 41.Rd2 Bc4 42.Rxd4 Kc5 43.Rd2 a5 44.f4 a4 45.f5 b5 46.Kf4 b4 47.Nd3+ Bxd3 48.Rxd3 Kc4 49.Rh3 Rf7 50.Ke5 50.g5 d4 51.f6 a3 52.b3+ Kd5 50...d4 51.f6 d3 52.Rh2 a3 53.bxa3 b3 54.Ke6 Rb7 55.f7 Rb8 56.Rxh7 b2 57.Rh1 d2 58.g5 b1Q 59.Rxb1 Rxb1 60.f8Q d1Q
