[11.exd5 Thanks for your anaylsis guys. It was very instructuive. If I could summarise, it seems to me that Black has big chances for the upper hand after 14.Ne3, but 14.Qe2 promises equality, at least after 15...Qd6! The only line that may give white equality after 14.Ne3 and the whole 15.Ke2 is Mike's 18. Nc4 move (if black insists on 15 ...f5). But it seems that black bursts through with a strong attack if he goes in for the knight exchange (18 ...Nxd4!). Either that or Claus-Juergen's idea of 15 ...Nf6 seems to give black a simper way to keep even a slight advantage, but 15...f5 is more ambitious. 11...Qxd5 12.d4 exd4 13.cxd4 Ne4 14.Qe2 (14.Ne3 Qa5+ 15.Ke2 (15.Nd2 Nd6 Claus-Juergen: "and d4 hangs"; 15.Kf1 Nf6 16.Bd2 Qh5 17.Bc3 0-0 18.Ne5 Claus-Juergen: "White has active play in the center") 15...f5 (15...Nf6 16.Re1 0-0 17.Kf1 Rd8 Claus-Juergen: "and the d-pawn looks doomed" 18.d5 (18.Bd2 Qb5+-/+ ) 18...Nb4-/+ Claus-Juergen: "If Black can reach this kind of position with natural, not hard to come by moves then I'd say the whole Ke2 idea is a failure.") 16.Bb3 Bd7 17.Re1 0-0-0 18.Kf1 (18.Nc4 Nxd4+ (18...Qb4 19.Kf1 Rhe8 20.Be3 g5 21.Nxg5 Nxd4 Mike Ogush: "=/+"; 18...Qb5 Claus-Juergen: "I suggest 18...Qb5 as an improvement for Black. The idea is to provoke a4 when the Bb3 is only defended by the queen which makes Nxd4 ideas once again valid. The pin also sets up threats against the Nc4 (Be6)." 19.Kf1 (19.Be3 f4 20.Bxf4 Nxd4+ 21.Nxd4 Bxd4 22.Kf1 Bc6 23.Qg4+ Kb8 Here Claus-Juergen's analysis is a little confusing, but it is still basically advantage to black; 19.a4 Qb4 20.Be3 (20.Kf1 Nxd4 Mike Ogush: "reduces Black's advantage" (20...Rhe8 Mike Ogush: "better than the similar position where the a-pawn has not moved since the queen is tied to the defense of the Bb3.") 21.Nxd4 Bxd4 22.Qxd4 Qxb3 23.Na5 Qb6 24.Qxb6 cxb6 25.Nc4 b5 26.Nb6+ Kc7 27.Nxd7 Rxd7 28.axb5 Mike Ogush: " Black will still have the pawn plus, but the extra pawn is part of the doubled isolated b-pawns and Black's king is still not very secure. I would evaluate this as equal. ") 20...f4 21.Bxf4 Bxd4 22.Nxd4 Nxd4+ 23.Kf1 Bf5 Claus-Juergen: "with an overwhelming game for Black") 19...Be6 20.Qe2 Nxd4 Claus-Juergen: "is definitely advantageous to Black") 19.Nxd4 Bb5 20.Nxb5 Qxb5 21.Qc2 Mike Ogush: "Black doesn't have enough compensation for the piece". But, whites weak-points: f2 pawn; King position; Pin on c4-knight; Undeveloped a1-rook. Whereas Black's strong points are noticable: strong dark squared bishop; dominateing knight; Active d-file rook, and easily-made-active h to e file rook; relatively safe king; active queen cooperating with the rest of the army. Concretely, 21 ...Bxf2! leads to a big black advantage 21...Bxf2 This is very messy stuff that follows, and I can only suggest that black has the better of it becasue of the previous mentioned advatages and disadvantages - and because Junior 8 has a rating of some 2 pawn advantage for black. 22.a4 (22.Rd1 Rxd1 23.Qxd1 (23.Kxd1 Qc5 24.Bf4 g5 25.Nd2 gxf4 26.Qxc5 Nxc5 27.Bc2 Rf8 and black has two extra pawns.) 23...Rd8 24.Qc2 Ba7 25.Bf4 g5 26.Bh2 Rd2+ 27.Qxd2 Nxd2 28.Kxd2 Qd5+ 29.Kc3 Bd4+ 30.Kc2 Qxg2++- ; 22.Be3 Bxe3 23.Kxe3 Rhe8 24.Kf3 Qc6 25.Rad1 Rxd1 26.Rxd1 Nc3+ 27.Kf2 Re2+ 28.Qxe2 Nxe2 29.Kxe2 Qxg2+ 30.Kd3 Qe4+ 31.Kd2 b5 32.Ne3 f4 33.Nf1 f3 34.Kc1 f2 35.Bd5 Qf5 36.Rd2 g5 ; 22.Bg5 could be the best. Principle here is to swap off as much as possible, making any black attack less dangerous. 22...Bxe1 23.Bxd8 Rxd8 24.Rxe1 Qc5 25.Ne3 Qe5 26.Bd5 Rxd5 27.Nxd5 Qxd5 28.Kf1 Qxa2 Perhaps black has the advantage here. The previous line is rather speculatuive.) 22...Qb4 23.Rf1 Rhe8 24.Kf3 Ba7 25.g3 Nc5 26.Ba2 Ne6 27.Kg2 Nd4 28.Qd1 Re2+ 29.Kh1 Qc5+- ) 18...Nxd4! ) 14...f5 15.Ne3 Qd6 Claus-Juergen: "is an improvement " (15...Qa5+ 16.Bd2! ; 15...Qb5 16.Qxb5 axb5 17.Nd5 Kd8 18.Bf4 Nd6 19.Bg5+ Kd7 20.Be3 Mike Ogush: "+/=") 16.0-0 (16.Nxf5 Bxf5 17.Bxe4 0-0 Claus-Juergen helpfully adds: "and I think Black has compensation for the pawn because of superior development, the half-open f-file and the weakness of the d-pawn. In fact I'm not so sure if White can hold the pawn." 18.Bxf5 (18.Qc4+ Be6 19.d5 Rad8 20.0-0 Bxd5 Claus-Juergen: "=") 18...Rxf5 19.Be3 Qe6 20.a3 Claus-Juergen: "preparing the Ra1 to move" (20.Qd2 Raf8 ) 20...Rd8 21.Rd1 Rfd5 22.Rd2 Qf6 ) 16...0-0 Claus.juergen: "Poses no problem for black"]
