My Fourth Loss in a Row

Nobody else has submitted any analysed games, so I'll just present my loss to Anthony, my fourth loss in a row in this tournament.

  1. Well I did but was just a little late. Also the PGN viewer above is blocked from my work so I can't even see what Ian has written. But a bit of duplication won't hurt - here are snippets from my PGN file:

    I wasn't at the club for this game but as soon as I received the PGN from Ian I remembered his game from several other club players. I've seen the position at move 13. Qd4 about 4 times with Anthony as
    black so he happily invites opponents. Yet it bugs me because either way you look at it, 9. ..Kf8 or 9. ..Kd7 to me blacks position just seems like a real up hill battle. His king is vulnerable in the middle of the board and it seems white is a lot more comfortable with good room to gain initiative, or even an attack on the black king. However to be more objective we are talking about Anthony here who has probably looked at every single nook and cranny in these lines.

    Surprisingly after ..Kd7 engines get confused with the position and give a better evaluation straight away around a whole pawn, but as you play on a couple of moves this jumps back down to drawish again. This demonstrates how complex and unbalanced the position is. The following lines are generated using Houdini 3 i5 quad core machine.

    1. d4 d6
    2. e4 Nf6
    3. Nc3 g6
    4. f4 Bg7
    5. Nf3 c5
    6. Bb5+ Bd7
    7. e5 { The sharpest and most interesting line. } Ng4
    8. e6
    {A very interesting move, it looks flashy and invites black to enter a very tactical position
    but safe play from black doesn't give any edge for white.
    The position is equal. Preferred alternatives are 8. Bxd7+ +0.48, 8. h3 +0.36 }
    (8.Bxd7+{+0.48} Qxd7 9.h3 cxd4 10.Qxd4 Nc6)
    (8.h3{+0.36} Bxb5 9.Nxb5 Qa5+ 10.Nc3 Nh6 11.g4!)
    8. ..Bxb5
    { A sharp try on 8..fxe6 is 9.Ng5 but black gets a quick repetition!} ( 8. ..fxe6 9.Ng5 Bxb5 10.Nxe6 Bxd4 11.Nxd8? Bf2+ 12.Kd2 Be3+ 13.Ke1 Bf2+ )
    9. exf7+ Kd7? {This is really the move that has made me consume a lot of time for seemingly no reason. The correct safer option is Kf8 as follows}
    ( 9. ..Kf8 10. Nxb5 Qa5+ 11. Nc3 cxd4 12. Nxd4 Kxf7 {A complex yet equal position} )
    10. Nxb5 Qa5+
    11. Nc3 cxd4
    12. Nxd4 Bxd4
    13. Qxd4 Nc6
    14. Qc4 Qb6
    15. Qe2 h5
    16. h3 Nh6
    17. Bd2 Nf5
    18. O-O-O Ng3 {It is very odd that white has nothing better to do here than to just give up the exchange, it just demonstrates the complexity of the position. }
    19. Qd3 Nxh1
    20. Rxh1 Raf8
    21. Qxg6 Nd8
    22. Re1 { Computer moves have been played for the last 10 moves, all theory still? Here however 22.Nd5! is strong and takes the initiative. }
    ( 22.Nd5! {+0.93} Qc5 23.Qd3 Rxf7 24.b4 Qf2 25.Qc4 Qxg2 26.Re1 Ke8 27.f5! {Sets up a very nice attacking position indeed!})
    22. ..Rxf7
    23. Nd5 {If only Ian had seen Nd5 one move earlier as it doesn't gain any advantage here. In fact now although the position looks very dynamic Houdini evaluates the position as about equal. } Qc5
    24. Qg5? {Ian plays an inaccuracy here and hands over control, now black is better. Qd3 or Qe4 keeps a slight edge. }
    24. ..Rhh7 {Anthony returns the favour, black is much better after the following. }
    ( 24. ..Ne6 25.Qg6 Nd4 26.Nc3 Qf5 27.Qxf5+ Nxf5 )
    25. Be3 Qc6
    26. Bxa7 Rhg7
    27. Qxh5 Rxg2
    28. Rxe7+?? {Unfortunately here in the complexities Ian blunders badly, almost a whole rook.
    He must of hallucinated a tactic here which I know the feeling all too well. Black is completely winning now. Computer lines continue with 28.Nb6+ or 28.Qd1 both as about equal}
    28. ..Rxe7
    29. Qf5+ Ne6
    30. Nxe7 Kxe7
    31. Qh7+ Rg7
    32. Qh4+
