(RJ)} 2.exd5 Nf6 3.d4 {An alternative is 3. c4 e6!? going into the fascinating Scandinavian Gambit. (RJ)} Nxd5 4.c4 Nb6 5.Nc3 {Chessbase shows the more more common move to be Nf3. It has the advantage of preventing 5......e5. (RJ)} e5 {The sharpest and most popular move in this position in Chessbase. Black sacs a pawn for a lead in development and active piece play, in many lines winning the pawn back. (RJ)} 6.dxe5 Qxd1+ 7.Nxd1 Nc6 8.f4 {Again the preferred move on Chessbase. White hangs onto the pawn and says prove it. (RJ)} Be6 9.Ne3 Bc5 10.b3 O-O-O {Still following a main line in Chessbase. (RJ)} 11.Bd2 {Diverging from book. a3 or Nf3 are usual here. (RJ)} Nb4 {Black must make something happen before White catches up in development.Apart from the threatened fork, it prevents White for the moment from castling, which would bring White's rook onto the d file, But Deep Shredder (ratin about 2800) and Stockfish 7 (over 3300!) like Rd7 better.(RJ)} 12.Nf3 Bxe3 13.Bxb4 Bxf4 {Black has won back the gambit pawn, and has given White an isolated pawn, while still having a lead in development. But I did not appreciate here the fact that White has a considerable spacial advantage and pawn control of the centre, and that the black knight is awkwardly placed. Also the f pawn is backward on an open file. RJ)} 14.g3 Be3 {Probably a subtle inaccuracy, giving White a free tempo to put his king on a square which assists in the connection of his rooks. The bishop should go straight back to h6. (RJ)} 15.Ke2 Bh6 16.Bg2 Bg4?! {With the aim of winning the e pawn. Just a bit too ambitious. The simpler and more flexible Rhe8 was more consistent with the theme of this opening, namely to focus on quick development rather than material. (RJ)} 17.h3 Bxf3+ {Continuing with the faulty plan, White now has a slight edge.(RJ)} 18.Bxf3 Rhe8 19.Bc3 Kb8? {Jumping at shadows. Nd7 was best. (RJ).} 20.Rad1! {Posing some embarrassing questions for Black. (RJ)} Rxd1? {Weak, activating White's Queen's rook for him. Again Ne7 was called for. (RJ)} 21.Rxd1 c5 {Black finally realising he had to give up trying to win a pawn and start trying not to get crushed. Deep Shredder gives White here 1.91. (RJ)} 22.Kf2? {This eases the pressure on Black. Correct was a4. (RJ} Kc7 {Confirming that 19....Kb8 was a wasted move. (RJ)} 23.Bg4 g6 {With the idea of Bg7 and h5 (RJ)} 24.a4 {Gaining space and threatening to win the knight} Re7 {Forced, to keep the Rook out of d7 after the advance of the a pawn. (RJ} 25.e6? {Over-anxious to press home his advantage, and throwing it away . Probably assuming Black will take the pawn and overlooking Black's actual reply. Deep Shredder suggests 25. h4 Nd7 26. Rd5 b6 27. b4 cb 28 Bxb4 Nc5 (RJ)} f5 {Not fe which gives White a very strong position after 26 Be5ch Kc8 27 Rd6 (RJ)} 26.Be5+ Kc8 27.Bf3 Rxe6 28.Re1 Nd7 29.Bc3 Rxe1 30.Kxe1 {Deep Shredder now gives Black a .63 advantage (RJ)} Bg5! {Preparing to challenge White's black bishop on the long diagonal. (RJ)} 31.Bd5 Bf6 32.Bd2 Be5 33.Kf2 Nf6 34.Be6+ Kc7 35.g4 f4 36.Kf3 g5 37.Be1 Bd4 38.Bf5 h6 39.Ba5+ b6 40.Be1 Kd6 41.Bd2 Ke5 42.Be1 {White pretty much just has to mark time.and wait for Black to do something. (RJ)} Ne8 {Heading for d4 (RJ)} 43.Bd3 a5 {Wanting to keep the position closed, to reduce the activity of the White bishops. White's black bishop, which could otherwise pick off the base of Black's pawn chains, just can't get there. (RJ)} 44.Be4 Nc7 45.Bd3 Ba1 {To enable the knight to jump straight into d4 if the White bishop goes to f5 (RJ)} 46.Bf2 {If 46 Bf5 Kd4 (RJ)} Ne6 47.Bc2 Nd4+ 48.Bxd4+ Kxd4 {White is relying on the fact that the bishops are of opposite colours. Deep Shredder gives Black 1.96 here. (RJ)} 49.Kf2 Bc3 50.Ke2 Bb2 51.Kd2? {Making it easier for White. Better was Kf2. (RJ)} f3 52.Bd3? {Ke1} Bc3+ {Black also had Bf8! (RJ)} 53.Kc2 Be1 {Bb4 was stronger. (RJ)} 54.Bf1 Ke3 55.Kd1 f2? {Bb5 with the idea of Kf2 was much stronger. (RJ)} 56.Bg2 Kd3? {Again Bb4. (RJ)} 57.Kc1 Kc3 {I looked at Ke2, which wins the Black Bishop. But wanted to keep it simple and avoid any counterplay by the White king. (RJ)} 58.Kb1 Kxb3 59.Bf1 Kxa4 60.Ka2 Kb4 61.Kb2 a4 62.Be2 a3+ 63.Ka2 Bc3 64.Bd3 Bb2 65.Bf1 Kc3 66.Kb1? {Allowing Kg6!, forcing mate.by a2 (RJ)} Kd2? {Which Black misses. All above analysis with aid of Deep Shredder. (RJ)} {#R} 0-1
