Vienna Game: Anderssen Defense
  1. Ivory12 Go astro!
  2. omertil (2) Go Astro!
  3. omertil (2) They're 3-0 in Astro's favor until now, but rating is in 4hu's favor
  4. omertil (4) Astro reallin takin' his time in the opening
  5. Forhavu 5. fxe dxe 6. Nxe5 Qd4 7. Nd3 is interesting but scary
  6. Forhavu I could go d4 now before Nc6 which looks very nice for me
  7. Forhavu After 6..Bg4 my candidate moves are Qd3 and Nf3, honestly I'm okay with the self pin for nowand it won't last very long after h3
  8. Forhavu So 7. h3 is off limits due to Qh4+, same with moving the d4 knight. Be2 seems to work
  9. omertil (6) What's the threat of 6...Ng4?
  10. Ivory12 no threat but no danger either due to qh4+ and bxd4 overloading the white queen I guess
  11. Forhavu 8. BxN BxB 9. QxB BxN 10. Bd2 looks great to me and 8. BxN BxN 9. QxB BxB 10. O-O looks fine too
  12. omertil (9) So material is even but the white king stuck in the center?
  13. Ivory12 I guess so
  14. Ivory12 I'll say that isn't the line 8. BxN BxN impossible because of 9. Bxc8?
  15. Ivory12 but it wasn't played anyway
  16. Ivory12 I suppose 9. Bxc8 Bxc3 10. bxc3 Qxc8 damages White's structure more
  17. Forhavu 11. Qe2 threatens a fork and after BxN 12. BxB fxe4 13. O-O-O d5 14. Qb5 looks strong
  18. Forhavu But what's so bad about exf5 Re8+ Kd1? uncastled and hard to develop the queen rook but it also seems fine
  19. Forhavu I don't see a lot of initiative for me though especially if Black plays something like c6 to restrict the knight
  20. omertil (11) So 11...Bxc3 12. Bxc3 fxe4 13. 0-0-0?
  21. omertil (11) I'm not sure Black should give up the dsb
  22. omertil (11) And the e4 pawn will be weak?
  23. Forhavu Another free pawn offer, but this one looks good to me, or at least it seems simply wrong to decline it
  24. Forhavu Now there's two fork threats, one on the bishop and the other on the rook
  25. Forhavu I'm thinking Qd5 wins at least the exchange, 13. Qd5 BxN 14. QxR Bxb2 15. Rb1 Qf6 16. c3 interference wins I think
  26. Forhavu if black plays BxB+ instead in that line I don't see any good followups, I can probably play Rd1 and Kc1
  27. Forhavu Also instead of c3 there's Qb7 with a similar effect
  28. Forhavu This is very delicate, I need to consolidate everything and not lose too many pawns. c3 looks really good here
  29. Forhavu I'm okay with simplfying as well because I have a strong passed pawn now
  30. Forhavu Nc5 looks really strong for Black, I'l probably step over to c2
  31. Forhavu I was thinking e5 but black just plays Ne4+ anyway and then takes
  32. Forhavu g3, Rhe1 and Rad1 are all moves I'd like to play to consolidate
  33. Forhavu hmm Qf5 is a real threat, I missed that. maybe b4 will let me hide on b2 and also help the queen get past the knight
  34. Forhavu Weakens c3 a lot though
  35. Forhavu I'd rather not block my a pawn with Ka3 but Kb3 allows some checks, not sure how good they are after c4 though
  36. Forhavu Well Qd5+ c4 Qg2 is maybe a little scary. Qd4 seems to do well
  37. Forhavu After Ka3 I'm not happy with Qd5 as well, threatening Ra8
  38. Forhavu and if I run my queen away the rook check comes anyway and i have to sac the queen, so Kb3 it is I guess
  39. omertil (24) 24...Nc5+ 25...Rb8+ too much?
  40. Forhavu Still have to be very careful but I think Black's attack is close to over
  41. mforg How about take on b4
  42. Forhavu The passed pawn is worrisome still
  43. Forhavu Qd2 is interesting but Qc3 works just fine
  44. Forhavu Qe2 Rad1 Nf2 Rhe1 seems good for me too
  45. omertil (24) Ooo
  46. omertil (24) Qd2 Qc3 Nc5+
  47. Forhavu that's suprising! don't think I can afford to take it
  48. Forhavu 25. KxN Rb8+ 26. Kc3 Qb2+ 27. Kd3 Qd2+ 28. Ke4 Re8+ 29. Kd5 black has Qg2+ Qe4 Qxe4#
  49. Forhavu I can't go to the other file because of Qa8+ so I can't take the knight at all
  50. Forhavu I was definitel wrong about the attack being over
  51. Ivory12 Nd3? Qxe2 Qb7+
  52. Ivory12 or Rb8+
  53. Forhavu might be time to give back the exchange and play something like a4 to shield my king from rook checks and to get my own ideas rolling
  54. Ivory12 you don't just give back the excahnge though
  55. Ivory12 a4 Nxe1 Qxf3 Nxf3 and how do you stop the e pawn
  56. Forhavu then there's Rb8+ Kc2 Rb2+ QxR NxQ KxN and it's 2 rooks and a pawn vs the queen
  57. Forhavu well assuming I can take the e2 pawn which I'm not sure
  58. Forhavu I could start with Kc2 NxR RxN that seems a lot safer and dI still have my passed a pawn
  59. Forhavu 30.. Re8 31. Qd3 Qxh2 32. Rxe2 RxR+ 33. QxR and black can't take g3 because of mate threat
  60. Forhavu Qh5 is the only non queen trade that stops mate
  61. Forhavu I think I win that endgame due to the passed a-pawn
  62. Forhavu I think this is definitely winning, plus the time advantage is great
  63. Forhavu Tempted to play something silly like Qb3, don't know what that really accomplishes
  64. Forhavu It does take control of the only other open file, rook has to pick a semi-open file and if Ra8 I have Qa4
  65. Forhavu adds two attackers to e8, that seems really good
  66. Forhavu But after Rg8 I don't feel like going Re8 and undefending my king from checks
  67. Forhavu There's still not that many good checks and the rook can always come back down
  68. Forhavu Qb3 at least seems like a low risk move
  69. Forhavu I want to find the most challenging, sharp continuation to utilize the time pressure
  70. Forhavu With everything held together a4 looks good and makes progress
  71. Forhavu Qh1 is maybe a problem I should have calculated but it should dbe fine
  72. Forhavu Should be careful that my queen is undefended, I don't want to lose it to some skewer
  73. fake_switch (37...h6) goooooooo astro!!!
  74. Forhavu g5 feels like a mistake maybe. I have Qb2, Qc3 and Qg6
  75. Forhavu 39. Qg6 Qh2+ 40. Kf3 Qh1+ 41. Kg4 and the checks run dry
  76. omertil Draw would be fair here
  77. Forhavu might use the checks to wiggle my queen down to g4 and only then take the pawn
  78. Forhavu hm thinking of repeating because Ke1 might work instead
  79. Forhavu This should definitely be a win now
  80. Forhavu I was expecting Qh7 to trade off queens
  81. omertil (49) Oh boy
  82. omertil (51) wpgg
  83. Forhavu Tiring to be on the defense for so long, that was a wild attack
  84. Forhavu Thanks for the game @Astronominoff and good luck in future rounds!
  85. fake_switch ggs
