Indian Defense: Knights Variation
  1. AACtrl (7.c4) expected 6.c3
  2. AACtrl (9.b3) 9...Qc7 Bf4 bothering me
  3. AACtrl (10.Bb2) 10...Qc7 or d5? 10...d5 Ne5!?
  4. AACtrl (14.Rd2) 14...b5 doesn't work yet, so 14...Qb8? or Rfe8?
  5. AACtrl (14.Rd2) 14...Nc5 does nothing that I can see
  6. AACtrl (15.Qd1) 15...Rfe8 or 15...b5!?
  7. AACtrl (15.Qd1) 15...b5 cxb5 axb5 b4 then?
  8. irongalaxy (15.Qd1) go irish! (or go go irish?)
  9. AACtrl (16.e3) seems like they don't know what to do either
  10. AACtrl (16.e3) 16...b5 cxb5 axb5 b4 d5 a3 then?
  11. AACtrl (16.e3) d5 Nxb5 too
  12. AACtrl (16.e3) no clue how to continue
  13. irongalaxy (16.e3) I don't usually play 1. d4 so this is not a structure I know well
  14. irongalaxy (16.e3) However! That d6 pawn seems like a potential weakness
  15. AACtrl (16...Nc5) the only piece I can move, don't know what for
  16. AACtrl (16...Nc5) was 15...Rfd8 better? to enable Bd8-Bc7
  17. AACtrl (16...Nc5) was 16...d5 cxd5 Nxd5 possible?
  18. AACtrl (17.Qe2) 17...d5 cxd5 exd5!? Nd4 very bad
  19. AACtrl (17.Qe2) 17...Nce4 Bxe4 does nothing
  20. AACtrl (17...Nce4) just trade the silly knight
  21. AACtrl (19.Rcd1) 19.c5 b5 cxd5 Rxc1+ Bxc1 Bxd6 Bxf6 hmm not sure
  22. AACtrl (20...b5) and I chose this setup to cure my time trouble addiction... ><
  23. VicPez White maybe has 22. Bb4 to fix the b5 pawn, followed up by Nd4 or Bf1?
  24. VicPez No, I guess ...Nd5 is a good antidote as soon as Black's bishop hits b4.
  25. VicPez Unless White is feeling a double exchange sac on d5, which I'm sure would be dumb.
  26. AACtrl (23...h6) 23...Qa8!? Bxf6 Bxf6 Rxd6 Rxd6 Rc2...
  27. AACtrl (23...h6) pushing d6? gives away e5 square
  28. AACtrl (24.Kh2) here goes...
  29. AACtrl (24.Kh2) 24...Qb7 or Qa8?
  30. AACtrl (24.Kh2) or Qc7 then Ra8?
  31. AACtrl (24...Qb7) 25.Nh4 Bxg2 Nxg2 Ne4!?
  32. AACtrl (26.Nxg2) 26...Ne4 Qf3!? or even Qg4
  33. irongalaxy (26.Nxg2) Probably Black is doing fine after ...d5
  34. VicPez Yeah, that does end up looking just like a very good QGD, doesn't it?
  35. irongalaxy (26.Nxg2) Black looks a bit better here but this is the kind of game where whoever doesn't blunder in time trouble will win
  36. AACtrl (26.Nxg2) 26...Ra8 Bxf6 Bxf6 Rxd6 Rxd6 Rxa2 Rc2 Ra1?
  37. irongalaxy (27.f31⁄2?) I would refuse if I were Black
  38. irongalaxy (27.f31⁄2?) I also thought that Ng2-f4-h5 was an idea here
  39. AACtrl (27...Ra8) can't, we're down on the score.
  40. AACtrl (27...Ra8) given my current losing streak, I would take the draw otherwise
  41. irongalaxy (29.Ne1) What is Black's way in?
  42. VicPez I'm not sure Black has a way in, but I think that any trade of pieces should be somewhat favorable.
  43. irongalaxy (29...Nd7) Indeed, the a2 pawn is a long term weakness
  44. irongalaxy (29...Nd7) White can play e3-e4 here, I think
  45. irongalaxy (29...Nd7) 30. e4 dxe4? 31. Bxg7!
  46. VicPez Nice trap!
  47. irongalaxy (30.Nd3) Although 30...e5 may be annoying in that line
  48. irongalaxy (30.Nd3) White is playing very patiently
  49. VicPez I think my first instinct here would be 31. ...Rc6. Would threaten to double on either file.
  50. irongalaxy (31...Nxf6) I don't mind the trade
  51. VicPez I can't tell if ...Rc3 is good. It looks gorgeous, but does it actually do anything? there are a whole lot of pawns on that third rank.
  52. irongalaxy (32...Qc7) Qc3 is now annoying in some lines
  53. irongalaxy (33.Nd3) Of course it loses to Rc1 now
  54. VicPez I'd be curious to see how White responded to ...Nh5.
  55. irongalaxy (33...Qd6) Probably f3-f4 in that case
  56. irongalaxy (33...Qd6) But agree that's the spirit
  57. irongalaxy (33...Qd6) Rc2 grabs the file now?
  58. VicPez Yeah. Probably in White's best interests even if trades feel shaky.
  59. irongalaxy (34.Kg2) e4 is also screaming to be played
  60. irongalaxy (34...Rc3) Probably that was better than either Kg2 or Rc2
  61. irongalaxy (35.Ne1) Now i'd be scared to play it
  62. VicPez (35) Maybe ...Nh5 f4 Nf6, looking at ...Ne4?
  63. irongalaxy (36.f4) If ...Nf6 then e4, I think
  64. VicPez Good catch!
  65. VicPez Wonder if ...Qc6 would be a decent answer.
  66. irongalaxy (37...Ne4) In that line exd6 and like Kh2
  67. irongalaxy (37...Ne4) But it's a good answer
  68. irongalaxy (37...Ne4) exd5 not exd6
  69. AACtrl (37...Ne4) the torture...
  70. irongalaxy (38...Rac8) Nd4 only move?
  71. VicPez Not sure what Black wants to do here. Even thought it feels like this should be a huge advantage.
  72. VicPez (39...Qb8) Maybe ...e5 is a big threat now?
  73. DrVonGoosewing Why wasn't e5 a threat before?
  74. irongalaxy (40.Kf3) ...e5 gives White some hope
  75. DrVonGoosewing fxe Qg6
  76. irongalaxy (40.Kf3) ...e5 Nb5
  77. VicPez Nb5 seemed like White's threat there, but I didn't actually calculate deeply enough to see if the fork did the trick.
  78. irongalaxy (40...g5) Regardless fxe would be the wrong response I think
  79. DrVonGoosewing ...e5 Nb5 ...Qg6
  80. VicPez (41) Is Black's plan ...gxf4, ...Kh7, ...R... nevermind.
  81. irongalaxy (42.Qe2) ...gxf4 gives White some life
  82. irongalaxy (43...Ra8) ooh a4! is an idea
  83. VicPez That's actually a really cool line -- Black tries to pressure a2 but lets White tactically get rid of the weakness.
  84. irongalaxy (44.Qe2) Only works with the queen on e1
  85. irongalaxy (44.Qe2) Alas
  86. VicPez 46...f5+ was probably worth a shot.
  87. VicPez Might still be.
  88. irongalaxy (47.Rxd3) It looks pretty crushing
  89. irongalaxy (47...Qxa2) This gives White some hope to defend
  90. VicPez It does, but it feels like White is walking a tightrope. Any endgame is hugely in Black's favor.
  91. AACtrl (48...Qb1) 48.Qxa2 Rxa2 Nc6 problem :x
  92. irongalaxy (48...Qb1) f5 is a big threat again
  93. irongalaxy (49.Qb5) I think it just wins
  94. VicPez Maybe ...Qe4+, Kh6, ...Qg6+, ...f5#?
  95. VicPez Wait, not quite mate, but close enough.
  96. VicPez (49...Qe4+) Maybe Kh6 e5?
  97. irongalaxy (49...Qe4+) There's also Kh5 Qg6+ Kg4 Ne4+ winning a rook
  98. irongalaxy (50...Nf3) If Kh4, idk
  99. VicPez Oh, this seems reasonable.
  100. DrVonGoosewing nice mate
  101. DrVonGoosewing not g3 oops
  102. DrVonGoosewing gg
  103. VicPez gg, folks! That was a heck of an ending!
  104. DrVonGoosewing enjoyed that.
  105. goirish well that was a wild game
  106. AACtrl computer doesn't help at all in these things
  107. goirish no it doesn't
  108. AACtrl 40...e5 Nf5 Rc2 Qe1 Nf2! *mindblown*
  109. AACtrl of course with only one minute...
