Neo-Grünfeld Defense: Classical Variation
  1. lc91 go Jensen!
  2. JensenUVA my opponent plays a number of different openings but I rather suspected we would get this position. Not much "prep"
  3. JensenUVA it's just a decent position but I decided I liked the lines with dxc4, Nc6
  4. lc91 open catalan, right? should be fun!
  5. lc91 gotta say, that's a strange structure with Nf6, Be6, Nc6 all in front of pawns
  6. masedog91 Very solid though
  7. JensenUVA Qa4 Nd5 I think has been played before. White has e3 or Qd1 in order to shore up d4, and then we think a bit
  8. JensenUVA ok that's the end of whatever I know about this position. I think this must be full equality for black due to the development.
  9. lc91 probably play on the queenside?
  10. JensenUVA Nxd4 doesn't work unfortunately but I had thought Nb6 Qd1 Bd5 was simple and ok for black.
  11. KS_Legion_Legionowo I self-buried with white in just 10 steps; it's nearly an artistic achievement.
  12. AACtrl tell me about it lol
  13. JensenUVA ... e5 was the plan but ... e5 16. Nc5 Qc8 17. d5 was annoying. I feel black *should* be better but I also just don't know
  14. lc91 I'm assuming white wants to play 19.Nxd5 Qxd5 20.Nc3
  15. lc91 oh they cant
  16. lc91 knight would be pinner
  17. lc91 pinned*
  18. lc91 they may need to play something like Nx Qx, f3 or Qf3?
  19. lc91 oof low on time for this middlegame with lost of pieces
  20. lc91 20.Qxc4 and Nxf4 seems good for black
  21. lc91 and if either Q or N take c3, I'm assuming exd
  22. lc91 I wonder if there, white can play an intermediate move like Rd1
  23. lc91 I don't believe that 20...exd4 Qxc4 dxc3 ends very well for white
  24. lc91 problem with something like Rd1 is black can sidestep with Qc6+
  25. lc91 how does white save the knight now? (22)
  26. lc91 Bb2 Nxb2 and same problem
  27. lc91 maybe move it I guess
  28. JensenUVA I suspect that b4/a4/a5 was not the correct plan. I was interested in ideas with Nc5 and with f4 for him
  29. lc91 But that loses the rook?
  30. lc91 22...Qxc3 Qxc3 Bxc3 and both bishops are staring at a rook, so that still loses a piece for white
  31. lc91 they can't afford to take the rook first before the queen exchange because the queen is hanging on b3
  32. lc91 wait... can't white just play Rac1 here?
  33. lc91 Rd3 maybe?
  34. lc91 25.Rfd1
  35. lc91 it's probably one of those engine draws but we'll see what humans do
  36. lc91 the extra pawn black has is passed though
  37. lc91 and the bishop controls the promotion square
  38. lc91 32...Ra8 and push?
  39. lc91 hmm doesn't this allow Ra7 and then Ra1?
  40. lc91 oh Ra1 is covered by the bishop. Ok so it may take a couple moves for white to attack the pawn again
  41. lc91 35.Nb7
  42. lc91 Rc7
  43. lc91 hmm is there a way to play Bd4 in time here?
  44. lc91 if white wants to play, this may take a while.
  45. lc91 especially if white manages to trade some pawns
  46. lc91 i mean do people know theory for a R vs R+B endgame?
  47. JensenUVA this is actually annoying to win somehow
  48. lc91 I was thinking of protecting the bishop with 54...Rb6
  49. lc91 and then go for the pawn on h4 with Kh5
  50. JensenUVA but I think that does it... good lord
  51. lc91 well done!!
  52. lc91 gg
  53. JensenUVA I almost don't want to know what I missed
  54. KS_Legion_Legionowo Don't press analysis for few days
  55. JensenUVA I won't - yeah I am going to try to go over it as a human as well
  56. KS_Legion_Legionowo I missed your Re1+
  57. JensenUVA when the knight was pinned - yeah... I thought before that at some point you should've gone for rooks on the 7th
  58. KS_Legion_Legionowo I was hoping that without the "a" pawn I could search for some fortress
  59. JensenUVA Right. I was actually very nervous at that moment because I thought if I had miscalculated I was just losing the a-pawn for nothing but
  60. KS_Legion_Legionowo I was hesitating between passive defence with Rd1-d2 and active counterplay by Rd1-d7. I guess active counterplay is always more valuable.
  61. JensenUVA oh good lord someone else has hit it
  62. KS_Legion_Legionowo Guys, who pressed the analysys request?
  63. KS_Legion_Legionowo Nobody is brave enough to admit having commited this abominable request sin? I guess he has just escaped.
  64. KS_Legion_Legionowo But the eval graph confirms my feelings throughout the game, I was much worse out of the opening and then it got only more unpleasant.
  65. KS_Legion_Legionowo I'm to easy to prep for me.
  66. KS_Legion_Legionowo We could learn so much from our own analysis, and only then computer one. Why must some idiot hit the request button. Can't they read...?
