Queen's Gambit Declined: Three Knights Variation
  1. LarsenB Nf2+ Qxf2 Bxd3 looks even stronger than taking on c7
  2. somethingpretentious Nc3+ just bx
  3. mmatros they both look pretty nasty, white is totally exposed
  4. glbert i dunno. the lsb is undefended.
  5. glbert i wonder how sgis' brain is doing.
  6. mmatros right, of course, Bxd3 has to be next after Qxf2
  7. Lukhas poorly, he's usually asleep at this hour
  8. somethingpretentious not Bxd3
  9. somethingpretentious Nxa3 surely
  10. somethingpretentious Bxa3*
  11. somethingpretentious hmm although white then has Bxf5 and Bxh7+
  12. mmatros right, that allows Bxf5
  13. Lukhas yeah that B is hanging on f5
  14. Lukhas I'd trade it just because I'm too lazy to calculate
  15. glbert i think 12...Nxf2 was simpler.
  16. somethingpretentious yeah but my point is that Bxa3 and Bxb2 is also a good threat
  17. somethingpretentious nevermind
  18. somethingpretentious queen still defends b2
  19. glbert this happens when sp is spectating games on week nights.
  20. somethingpretentious happens on most games I spectate tbh
  21. LarsenB he could maybe even start with Bxa3 right away, and then play Nxf2, so that after Bxd3 the c7 bishop is still attacked, plus can play Qxa3
  22. somethingpretentious haha stone cold with Rc8
  23. Bmoney_o yikes
  24. glbert absolutely, poor sgis.
  25. mmatros Nh4, the hell with it
  26. LemuelGullible Bxe4
  27. LarsenB sadly Bd6 dowsn't work because Nxd6 defends the rook
  28. LemuelGullible Bxe4 Rxc7 Bxf5 Rxc2 Bxc2
  29. Bmoney_o Bd3?
  30. mmatros Bxe4 Bxe4
  31. Bmoney_o opps I meant Bd6
  32. LemuelGullible Rc1?
  33. LarsenB Rc1 Nxf2 again I guess
  34. Bmoney_o Bd6 Rxc2 Bxe7 Nxf2+ Ke1 Bxa3
  35. mmatros Bd6 Nxd6
  36. LemuelGullible Rc1 Nxf2 seems alright for white
  37. LemuelGullible ah nvm
  38. LemuelGullible is bad
  39. mmatros surely now Nxf2
  40. glbert how about Ra7, is that stupid?
  41. glbert i have stopped believing in Nxf2. :D
  42. LarsenB on Ra7 I would try the crazy Bxe4 Bxe4 Bd8
  43. LarsenB ah, nope, Bxc2 is check
  44. mmatros I can't make anything work, black has too many threats
  45. mmatros I'm starting to believe in your Ra7, glbert
  46. glbert i have sucked at guess the move so far this game.
  47. mmatros looks like it works, though
  48. glbert see?
  49. Lukhas this looks winning, doesn't it?
  50. mmatros sure
  51. Lukhas assuming you don't hang a backrank
  52. mmatros Bxb6 wheee
  53. glbert a pawn is a pawn, right?
  54. sgis can I be extra greedy and take or just go back? questions
  55. Bmoney_o Uh B d6 now?
  56. JonathanCoffin After bxb6 would it be rook exchange and then take on a3?
  57. Bmoney_o Nah
  58. Bmoney_o nvm
  59. JonathanCoffin Well let’s see what happens now
  60. glbert whatever it is, i don't think it will be good for white.
  61. LarsenB can even play Nd7 first, since Rxc8 Rxc8 doesn't look good
  62. mmatros wish I could pause this, but I have to run
  63. mmatros gl holding this, white
  64. JonathanCoffin I like nd7 too
  65. sgis just Ne7 is ok here …
  66. sgis yep … missed that move
  67. Rise just win LOL
  68. sgis can't go to c7 because of Rc8. mh this is getting v uncomfortable
  69. Bmoney_o Nc2 Bxc2 Qxc2 Nxb6 Qc6?
  70. Bmoney_o Get's a pawn back at least and some good attack
  71. LarsenB on Nc2 just take on b6, the Bb4 is defended
  72. Rise i'm more like just Rc8
  73. Bmoney_o aaaand that hangs the queen with rc8
  74. Rise black has too many good options
  75. Rise its likely that if you play randomly you still stumble upon good moves
  76. LarsenB not sure if he could have tried 18.Ne5
  77. glbert white has the two Ns now though. i like white.
  78. Rise maybe had to take a3
  79. Rise Nc2 Nd4 might work
  80. Bmoney_o It's got to be like -3 or -4 at this point
  81. Rise Kd1 loses to Rc8
  82. LarsenB now Kd1 Rc8 and how to deal with c1?
  83. Rise this seems pretty holding
  84. JonathanCoffin Rc8 still here
  85. Rise it's a miracle
  86. LemuelGullible rc8 nd4
  87. LemuelGullible nfd4 that is
  88. JonathanCoffin Then bxn qxb queen takes e3
  89. JonathanCoffin ?
  90. LemuelGullible bxn nxn
  91. LemuelGullible nxb
  92. JonathanCoffin I meant now sorry
  93. LemuelGullible ah yes
  94. LemuelGullible thats possible
  95. LemuelGullible but then Kb1 and white finally gets to actovate the rook, no?
  96. sgis I have Nd4, holding everything together, interestingly - or?
  97. LemuelGullible yes, ti seems to hold
  98. sgis of course I calculated that move 10 moves ago :)
  99. Bmoney_o Wow, hell of a hold right now
  100. Rise should be able to change target
  101. Rise Qa5 Rb8 or something
  102. sgis still a lot of pressure to deal with though
  103. LemuelGullible Qa5 looks good
  104. Rise maybe black has lost the thread
  105. Rise it looks like all pieces are on their good squares
  106. Rise but they arent
  107. Rise the c-file has been exhausted
  108. sgis not sure how he can increase the pressure
  109. LemuelGullible maybe try to push the a pawn
  110. LemuelGullible a5
  111. Rise i guess this is a slightly worse Qa5
  112. Rise but definitely respectable
  113. Dmathman I believe he is trying to use his darksquared bishop to get rid of the defender
  114. Rise maybe Bc5 just works, yeah
  115. LemuelGullible but that gives white time to play Kb1 and Rc1
  116. LarsenB or he's fishing for b3 Qc3 (threat Qa1#, N still pinned)
  117. Rise i mean, if we trade Bc5xd4 then white is totally locked
  118. Rise then some kind of a5-a4 should work
  119. LemuelGullible without the dsb white can just play a3 to defend that, no?
  120. Rise then there might be doubling on the b-file
  121. Rise the main feature is the pin on the c2-knight
  122. LemuelGullible also black still has back rank issues
  123. Rise which makes things really weird
  124. Rise can't defend b2 laterally
  125. Dmathman White is stuck defending for now. The back rank issues are immaterial.
  126. Rise yeah, i believe in this. Bxd4 and a5
  127. LemuelGullible after Bxd4 exd4 a5 a3
  128. LemuelGullible what is there for black?
  129. Rise white should probably just allow a3 and meet it with b3
  130. Rise a3 then just Rb8 and Qb5
  131. Rise and it's really awkward
  132. Rise it's better to close the b-file at all costs in that case
  133. Rise there might be some Rxb3 in that line but i'd just calculate when i get there
  134. Rise i thought 23..Bxd4 was necessary because of Ka1
  135. Rise but Ka1 certainly looks highly suspicious
  136. LemuelGullible Ka1
  137. LemuelGullible hm
  138. Dmathman It seems the pin remains because of the rook
  139. Rise actually yeah, Ka1 loses to Bxd4 instantly
  140. Rise very good
  141. Rise some random moves being played
  142. Rise that is in black's favor
  143. LemuelGullible yea now Ka1 is a noption again
  144. Rise ah, now Ka1 is a thing
  145. Rise Bb4 was pretty random
  146. Rise still, Ka1 doesnt solve the pin thing
  147. Rise yeah, white has real problems
  148. sgis ok cant get tooooo low on time. hard to defend without time :(
  149. glbert hard to defend with time.
  150. Rise yeah boiiii
  151. Lukhas go mdaw!
  152. Rise bxa3 forced
  153. Rise and then something terrible has to happen
  154. LemuelGullible bxa3 is mate though?
  155. LemuelGullible bxa3 Qc3+
  156. Rise and?
  157. LemuelGullible ah no
  158. Lukhas mate-ish
  159. Rise i'm looking more along the lines of Bc3
  160. LemuelGullible that is mate
  161. ventricule now it's mate
  162. glbert ouch.
  163. Rise probably Bc3+ and Rb8+ and exchange sac
  164. Rise looked mating
  165. LemuelGullible gg
  166. glbert good game.
  167. ventricule gg
  168. Lukhas gg guys!
  169. sgis gg
  170. Rise i guess Qc3+ and Ba3 also worked
  171. Rise many options
  172. LemuelGullible well played by both
  173. Lukhas woah that eval
  174. LemuelGullible white defended well but black patiently squeezed it out
  175. sgis was an interesting game a lot of stuff happening
  176. sgis and black kept the pressure very well
  177. sgis I felt if I got a few moves to organise I would have been ok
  178. sgis but yeah this whole early pawn grabbing stuff almost never works out
  179. Rise the pin on the Nc2 was forever
  180. Rise white would probably never be quite ok as long as that was a thing
  181. Rise the main thing about the opening is Bb4+
  182. Rise i'd consider Nxc7 on principle but that gets the knight trapped
  183. Rise so you probably just have to admit the mistake and retreat
  184. sgis yes
  185. sgis Bb4+ was strong
  186. sgis and I didn't adjust correctly
  187. sgis after that is was pretty much over
  188. Rise i mean, the thing with Nxc7 is that you would be able to defend the check properly
  189. Rise after Bb4+ it's already quite over as far as i'm concerned
  190. sgis I think I should have pulled back
  191. sgis or not even started going there in the first lpace
  192. Rise yeah, because Nxc7 would lose the knight
  193. sgis yep
  194. Rise so hindsight 20/20 is that you don't play Nb5, of course
  195. sgis anyways, was an interesting game
  196. sgis and learned my lesson (again…)
  197. Rise usually should castle before pushing if Bb4+ looks like it might be strong
  198. sgis yes
  199. sgis I thought I could just block but underestimated the pin
  200. sgis ah well… as I said … lesson learned
