  1. The_Wayward_Prince that position looks like black would probably manade to win
  2. The_Wayward_Prince Qg8 is an interesting idea for white
  3. The_Wayward_Prince Probably black needs to play 73... Qd8
  4. The_Wayward_Prince Or maybe not
  5. The_Wayward_Prince after Kh7 maybe it's all fine
  6. The_Wayward_Prince ahh
  7. Gingersquirrelnuts (72) Does this defend it? Not sure it does?
  8. The_Wayward_Prince 72. Qg8 Qxe4 Kh2 then black has to go g5 I think
  9. The_Wayward_Prince so it doesn't seem to work
  10. The_Wayward_Prince Bxe2 surely
  11. Macalda interesting
  12. The_Wayward_Prince Same thng as before. Black cannot win
  13. The_Wayward_Prince 74. Bxe2 Nxb3 Kh3 with the idea of playing g4
  14. The_Wayward_Prince the pawns will come off
  15. The_Wayward_Prince and white can hold
  16. The_Wayward_Prince You must take the queen.
  17. The_Wayward_Prince Yes!!!!
  18. The_Wayward_Prince Nice, Macalda
  19. The_Wayward_Prince even g4 now is great
  20. The_Wayward_Prince g4, swap it off, ram, the bishop into the last pawn, and we're out of here with a draw
  21. Macalda wait, for draw I just need to get rid of the pawns, right? I only JUST NOW realized that.
  22. The_Wayward_Prince yessssss!!!!!
  23. Kjar there is an actual way of getting mated with 2 knights, so we may be up for a 50-move delight in any case :)
  24. The_Wayward_Prince haha
  25. The_Wayward_Prince Come on. You're got this Macalda
  26. The_Wayward_Prince 75. g4!
  27. Wo_Cheng_Si_Le probably a draw
  28. The_Wayward_Prince YEssssssssss!!!!!
  29. The_Wayward_Prince Wooooo
  30. QEDemonstrandum easy draw now
  31. The_Wayward_Prince Go Macalda! Way to stick with it!
  32. The_Wayward_Prince Just back up the bishop and then slam it into g6
  33. Wo_Cheng_Si_Le unless I can somehow keep this pawn
  34. The_Wayward_Prince Sure. This is fine
  35. The_Wayward_Prince f4 is fine
  36. The_Wayward_Prince Yes
  37. The_Wayward_Prince Kh3 is good. No rush at all. No progress is a draw
  38. Kjar just h5 was good enough - now Nh5
  39. Kjar or wait, no, black would take with the knight
  40. The_Wayward_Prince Nh5 doesnt do anything
  41. QEDemonstrandum take h5
  42. QEDemonstrandum draw
  43. Macalda won't make it easy for me, will you! lol
  44. The_Wayward_Prince and h5 is no good
  45. Kjar yeah, true
  46. The_Wayward_Prince No. Don't take h5
  47. Kjar black will take with the king
  48. QEDemonstrandum yes nvm
  49. Kjar that's tricky - now f4 seems to fall
  50. The_Wayward_Prince Just wait.
  51. The_Wayward_Prince Bd1 and Bc2 maybe
  52. Macalda crazy, I really thought I had the draw at the end here, not seeing it now though
  53. Macalda oh, wait, just need to get bishop away and hope to trade it still for pawn
  54. The_Wayward_Prince This is bad
  55. The_Wayward_Prince Nxf4and how do we hold onto h4
  56. QEDemonstrandum cant
  57. Kjar yeah, gotta play Kh2
  58. QEDemonstrandum cause Kg4 ne3+
  59. The_Wayward_Prince f4 was bad
  60. Kjar Nxh4 and then g5 - now the pawn is on a dark square, so black can move knights around as much as needed to cover it
  61. Wo_Cheng_Si_Le I can get the pawn to a dark square now
  62. Kjar to cover g4 and eventually g2
  63. The_Wayward_Prince I thought it was okay at the time, but it wasn't accurate at all
  64. QEDemonstrandum yes shield the pawn with the knights from the B and gg
  65. The_Wayward_Prince Black can take his time to route the knight around
  66. Macalda this has to be draw for sure, now
  67. Macalda just need to not get forked or something dumb
  68. QEDemonstrandum i think it is a win for black
  69. QEDemonstrandum cause the B can be blocked by the knights from the pawn
  70. The_Wayward_Prince f4 didn't really do anything was the problem
  71. Macalda oh, or can his king secure a way to block me... ugh, learning a lot! lol
  72. Gingersquirrelnuts (84) It's a hard one to win, but guessing this is won for black with perfect play?
  73. The_Wayward_Prince It's easy to win
  74. Wo_Cheng_Si_Le I'm sure there is a page in the Dovoretsky endgame manual on this exact position, and I haven't read it
  75. The_Wayward_Prince Kf6 and Ne6 are coming
  76. Gingersquirrelnuts (85) FOund it
  77. The_Wayward_Prince uh
  78. Macalda not what I thought he was trying to do
  79. The_Wayward_Prince yeah, same Macalda
  80. Kjar probably the longest game of the 1st round
  81. Kjar at least, going in that direction
  82. Macalda so, if he blocks me off after I go c8, can my king hold it there long enough to reroute?
  83. Wo_Cheng_Si_Le I don't know, bring the king in front of the pawn, threaten some checks and try to block the bishop with both knights then move the pawn
  84. The_Wayward_Prince The game has been going for over three and a haf hours now
  85. Macalda forgot I can move the king
  86. Kjar may easily take another 30-40 minutes
  87. Macalda maybe I need to retreat altogether and have this same battle on the longer diagonal...
  88. jrcrawford512 Go black! Grind it out!
  89. Macalda yeah *says to self again* it is a draw now if I can do it on the long diagonal
  90. jrcrawford512 This must be exhausting
  91. Gingersquirrelnuts (90) Another chance to get a block in should be coming up?
  92. Macalda if I'm right about the long diag thing, I should have just rerouted... not move king
  93. The_Wayward_Prince Bf3 was proably much better
  94. The_Wayward_Prince Now can't black just play 95. Nf5?
  95. jrcrawford512 81 was the last pawn move FYI (94)
  96. QEDemonstrandum i think black should get his king to f4 and then block the Bishop with the two knights
  97. Kjar can move to g3 now
  98. Macalda so, unless I'm missing something, I can only stop it on long if I can somehow keep my bishop inside the king... may not be possible
  99. jrcrawford512 Restart the counter! Go black!
  100. The_Wayward_Prince How about 96. Bh1
  101. Wo_Cheng_Si_Le there moved it one square. one square every 20 minutes
  102. Macalda guess I should be thinking about other ways of stalemating...
  103. The_Wayward_Prince Bh1
  104. The_Wayward_Prince I think
  105. jrcrawford512 Bf3 here?
  106. Wo_Cheng_Si_Le I'm sure my opponent wants to strangle me by now
  107. The_Wayward_Prince Then the bishop can no longer be blocked, although the situatio is still dire
  108. jrcrawford512 (95)
  109. Kjar B@h1 is fine for black - they will be able to attack it with a Knight from f2 eventually, and place another knight on f3 to cover
  110. The_Wayward_Prince The alternative can't be better, though I'm thinkinh
  111. The_Wayward_Prince Otherwise something like Ndd5 blocking is going to come
  112. Kjar there should be some zugzwangs around to either make white K move away from g1 or the bishop from h1
  113. Kjar there should be some stalemate ideas too btw :)
  114. Macalda yeah, with the blocking diagonal thing, I can't stop it inside
  115. The_Wayward_Prince I agree that the situation will still be dire
  116. The_Wayward_Prince But leaving the bishop where it is also seems ineffective. Bh1 seems the most testing
  117. MrScribbles Wow, nice watchparty. Is someone saving the chat? It's hard for me on mobile
  118. Kjar yeah, true - the question is what can put more practical problems in front of black
  119. jrcrawford512 There may be checkmate possibilities with the king in the corner like that
  120. Gingersquirrelnuts (97) It's now 2 hours since I thought "I really need something to eat but let's just watch the end of this one"
  121. QEDemonstrandum ne3 and the white king is locked out
  122. The_Wayward_Prince I have no food at all unless I want to go out and brave the blizzard
  123. jcarmody (98) I've saved the chat.
  124. The_Wayward_Prince so your situation is better at least
  125. jrcrawford512 Don't blunder stalemate!!
  126. The_Wayward_Prince It's offical. White moves his bishop to g2 to make it a hundred mover
  127. pulsar512b if the pawn is traded for the bishop its a draw
  128. Kjar that's been the main topic for last 40 moves or so :)
  129. Kjar the struggle is real
  130. The_Wayward_Prince I think 101. Kf1 is sort of mandetory
  131. jcarmody (100) I've only got the chat from around move 55. :-(
  132. Kjar right out of the opening you mean :)
  133. freddy267t that's too bad, as chess was solved in the comments around move 20
  134. The_Wayward_Prince Now coming up on the four hour mark.
  135. jcarmody (101) Oh, no!
  136. pulsar512b if the pawn was a h pawn white'd have an easier time
  137. pulsar512b since there's that rly easy fortress where knight+pawn cant break a king on h1
  138. pulsar512b am i seeing progress
  139. Macalda thought he was going to go king e3 first
  140. Gingersquirrelnuts (102) Nh4 now?
  141. pulsar512b kf1
  142. pulsar512b oh wait
  143. pulsar512b that probably loses
  144. The_Wayward_Prince Now the king overs f3 though
  145. pulsar512b yeah it def does, you just waste a tempo with the knight
  146. pulsar512b i would have intuitively kept it on the long diagonal, but i guess ne4 is bad
  147. Kjar Ke4
  148. Kjar zugzwang here
  149. Gingersquirrelnuts (104) 4 hour mark hit!
  150. Macalda oh, I didn't consider Be2+ hm
  151. GreenPterodactylus Nf5 ne4
  152. QEDemonstrandum kf2 bh3 ng5 gg
  153. Macalda ah, I think I blew it
  154. Macalda not sure if I could force draw, but at least I see how he wins now, I think
  155. jrcrawford512 wow way to grind it out Wo_Cheng_Si_Le
  156. The_Wayward_Prince gg
  157. Kjar what a game!
  158. Gingersquirrelnuts (106) gg
  159. Kjar GG!
  160. The_Wayward_Prince Well fought on both sides
  161. Gingersquirrelnuts (106) *applauds*
  162. ECelal gg
  163. izzie26 too long for server analysis :)
  164. freddy267t gg both
  165. Macalda lol, that was lost for a lot longer than I thought it was! haha
  166. Wo_Cheng_Si_Le I think the longest game I've ever played
  167. Macalda I was thinking I still had real chance to force a draw when queens were traded
  168. Wo_Cheng_Si_Le I thought so too, because my pawns were in a bad spot
  169. Gingersquirrelnuts Bet WCSL is pleased that Macalda didn't accept that draw offer after about 40 moves :)
  170. The_Wayward_Prince You can
  171. Wo_Cheng_Si_Le Thought you might have been able to just sac the bishop
  172. The_Wayward_Prince stockfish is giving a crazy answer there
  173. The_Wayward_Prince but if you go through, you'll see that it works.
  174. The_Wayward_Prince 77. Bd1
  175. The_Wayward_Prince sockfish says Nc6
  176. The_Wayward_Prince but then you can play Bc2
  177. The_Wayward_Prince and you'll sac on g6
  178. The_Wayward_Prince It evaluates the position after Bxg6 as -1.4 which is incorrect
  179. The_Wayward_Prince since we know from theory that there is no forced win
  180. Macalda interesting, I'll have to look at that with a fresh brain
  181. Wo_Cheng_Si_Le wait, if Bc2 I have a knight guarding that, is that the right move number?
  182. The_Wayward_Prince the sequence is like this
  183. The_Wayward_Prince 77. Bd1 after stockfish's move, 77... Nc6 then 78. Bc2 followed by Bxg6
  184. The_Wayward_Prince this demonstrates that Stockfish does not understand the postion here, at least not the instantiation of Stockfish here on Lichess
  185. The_Wayward_Prince Leaving the N on d4 is better
  186. The_Wayward_Prince but there's still no way for black to make progress
  187. Wo_Cheng_Si_Le I'm seeing if 77.Bd1 stockfish says ...Nh5
  188. The_Wayward_Prince mine says different
  189. The_Wayward_Prince but Nh5 is fine
  190. Wo_Cheng_Si_Le then it takes two moves to attack g6. Bh4-e8
  191. Wo_Cheng_Si_Le but in the meantime Nc6 for black and take h4 with check
  192. The_Wayward_Prince So maybe we just leave the B on d1
  193. The_Wayward_Prince How about Kh3
  194. The_Wayward_Prince If N check, we can just go back
  195. The_Wayward_Prince or even Kg3
  196. Wo_Cheng_Si_Le yes the bishop staying on d1, but its very hard to calculate all the permutations with moving the knights with check and being able to
  197. Wo_Cheng_Si_Le attack h4
  198. Wo_Cheng_Si_Le Alright, great game! I think I need to find some sustenance and will have to analyizae this tomorrow
  199. Wo_Cheng_Si_Le Good luck the rest o the season!
  200. Wo_Cheng_Si_Le I'm studying this game on lichess.org/study/ib4bDDKE
