1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 5.c4!? [This variation of the Ruy Lopez is quite rare. Its main purpose is to have a strong point at d5 and limit Black’s responses. Here is another game: 5.c4!? Nf6 6.Nc3 Bd7 7.d4 exd4 8.Nxd4 Be7 9.Nxc6 bxc6 10.O-O O-O 11.h3 Re8 12.Qf3 c5 13.Bc2 Bc6 14.Bd2 Nd7 15.Nd5 Bf6 16.Bc3 Bxc3 17.Qxc3 Nf8 18.Rfe1 Ne6 19.b4 a5 20.bxc5 Nxc5 21.Rad1 Qb8 22.Rb1 Qa7 23.e5 Rad8 24.Nf6+ gxf6 25.Qg3+ Kf8 26.exf6 Re5 27.Rxe5 dxe5 28.Qg7+ Ke8 29.Qg8+ Kd7 30.Bf5+ 1-0 (Ilia Smirin (2480)-Janis Klovans (2420), Baltic Republics Ch., Kuldiga, Latvia, 1987)] 5…Nf6 6.d3 Be7 7.h3 O-O 8.Be3 Nd7 9.Nc3 Bf6 10.Ne2 Re8 11.O-O Nf8 12.d4 exd4 13.Nfxd4 Nxd4 14.Bxd4 Rxe4 15.Qd3 Bf5 16.Bxf6 Qxf6 17.Ng3 Re5 18.Qf3 c6 19.Rad1 Qe6 20.Qc3 Rd8 21.Rfe1 Re8 22.Rxe5 dxe5 23.Qb4 b5 24.cxb5 axb5 25.Bb3 Qc8 26.Nxf5 Qxf5 27.Rd6 Rc8 28.Qc5 Qb1+ 29.Kh2 Qxb2 30.Qa7 Ng6 31.Bxf7+ Kh8 32.Bxg6 hxg6 33.Rxg6 e4 34.Qe7 Ra8 35.Rg4 Qf6 36.Qxe4 Kg8 37.Rf4 Qd6 38.g3 Rf8 39.Rxf8+ Kxf8 (The last two moves were played so White would reach a winning queen endgame. However, having a winning advantage does not mean an easy-to-win advantage.)
40.Kg2 b4 (With both queens controlling the center the game is almost equal. Except White has an extra pawn.) 41.h4 c5 42.g4 g6 43.g5 Kg7 44.Kh3 Qc7 45.Qc4 Qe5 46.Kg2 Qc3 47.Qe4 c4 48.Qe7+ Kg8 49.Qe8+ Kg7 50.Qe7+ Kg8 (White of course could force a draw here. But he wants more. And advancing his pawns is the best way to increase his advantage.) 51.h5! gxh5 52.g6 Qg7 53.Qe6+ Kf8 54.Qd6+ Ke8 55.Qb8+ Ke7 56.Qxb4+ (If this move was not a check Black would have reasonable chances for a draw with …Qxg6+. This should be White’s method; willing to jostle for position and make a number of threats until it is safe for him to press his advantage.) 56…Kf6 57.Qxc4 Qxg6+ (Every pawn trade makes the position clearer to understand.) 58.Kh2 Qf5 59.Qd4+ Kg6 60.a4 Qa5 61.Qd3+ Kh6 62.Qe3+ Kg6 63.Qf4 Qd5 64.Qc7 Qf5 65.Qd6+ Kh7 66.Qd4 Qa5 67.Qd7+ Kh6 68.Qc6+ Kg7 69.Qb5 Qc7+ (Naturally White would win after a queen trade.) 70.Kg2 Qf4 71.Qd7+ Kh6 72.Qc6+ Kh7 73.Kf1 Qd4 74.Qc7+ Kh6 75.a5 Qd3+ 76.Kg1 h4 77.Qc6+ Kh5 78.a6 Qd4 79.Qe8+ Kg4 80.Qe6+ Kh5 81.Kg2 Qa1 82.Kh2 Qd4 83.Qe8+ Kg4 84.Qe2+ Kf5 85.Qf3+ Kg6 86.Kh3 Qa4 87.Qg4+ 1-0
