Owen Defense: Other variations
  1. SuspendedSeventh What's going on with that f4 pawn?
  2. bufferunderrun maybe 12...Qg4 was better
  3. bufferunderrun 13.Ne5 perhaps and then one needs to figure out if Rxf8 and Nxd7 works or maybe there is Bd2
  4. bufferunderrun though it looks like Nxd4 would be possible on Bd2 and Nxe2 would come with a check
  5. rojazu (9) its like a maroczy bind right translated by one square
  6. bufferunderrun that is of course if the queen goes to h6, otherwise it's a piece after Bxe2
  7. greysensei (13) was calculating Ne5 Qh4 Nxd7 Bxd4+ Bxd4 Qxd4+ Kh1 Qxd7
  8. SuspendedSeventh Obviously prophylactic against any kind of Bxd4+/Qxd4+
  9. SuspendedSeventh But it seems to me that black has a lot of time
  10. SuspendedSeventh (Tempi not clock)
  11. bufferunderrun hmm... if Qh4 there, then maybe g3?
  12. drchessdad I'm not sure whether White has enough for the f pawn to be honest
  13. SuspendedSeventh Doesn't look like it imo... almost seems white is the one under a lot of pressure, with that d pawn
  14. bufferunderrun right, no compensation, but it's still early to call it game over
  15. drchessdad yup of course, still have to prove the win
  16. SuspendedSeventh Game is far from over
  17. drchessdad surely White is thinking now about Rad1
  18. drchessdad Black should consider ..Nb4, I quite like the move,
  19. bufferunderrun Be4 could maybe work as well
  20. SuspendedSeventh Be4 looks interesting
  21. bufferunderrun Be4 Nxd4 Nxd4 Bxe4 Qxe4 could maybe just play e5, so probabøy doesn't work
  22. bufferunderrun *probably
  23. SuspendedSeventh Interesting...
  24. bufferunderrun maybe Bxf3 instead of Bxd4 was better
  25. SuspendedSeventh Perhaps looking for a perpetual?
  26. SuspendedSeventh Yea idk I was looking at Bxf3 but barely started calculating it before Black moved
  27. SuspendedSeventh Does black have like Rxf1 here?
  28. bufferunderrun sure
  29. bufferunderrun dropped the bishop as well :(
  30. bufferunderrun ah never mind
  31. bufferunderrun lol
  32. SuspendedSeventh Rf8 here?
  33. SuspendedSeventh Does that even work lmao
  34. SuspendedSeventh No it doesn't
  35. bufferunderrun doesn't drop the bishop, but Bxg2+ shoudl probably work
  36. SuspendedSeventh What about Qg4 now?
  37. bufferunderrun if Qg4 the bishop retreats
  38. SuspendedSeventh Ah
  39. SuspendedSeventh Wait after Bxg2...
  40. bufferunderrun 18...Bxg2+ Kxg2 Qg4+
  41. SuspendedSeventh Right
  42. SuspendedSeventh Wait after Qg4 bishop goes.. C3?
  43. SuspendedSeventh d3*
  44. bufferunderrun idk... maybe it's not that clear
  45. SuspendedSeventh Because I was seeing something like Bd3 Bxg2 Qxg2 now loses that rook on the first
  46. bufferunderrun Bxg2+ Kxg2 Qg4+ Kh1 hxg6 Rxd7
  47. SuspendedSeventh No I meant Qg4 before Bxg2+
  48. bufferunderrun I'm still talking about 18th move
  49. SuspendedSeventh Same
  50. SuspendedSeventh As in like 18... Qg4
  51. bufferunderrun you can't play 18...Qg4, Qf7+ Qh7#
  52. SuspendedSeventh Oh...
  53. SuspendedSeventh Damnit that's what I get for not looking at it enough
  54. Akibart How about Rxd7 here?
  55. bufferunderrun looks like the only try indeed
  56. SuspendedSeventh Rxd7 Rxe2 Rxg7+ Kxg7 Bxe2?
  57. bufferunderrun but Rxd7 Bxg2 seems to work for black
  58. Akibart Then white has to play Kg1
  59. rojazu (22) black has lovely co-ordination, Re4 and resigns probably
  60. bufferunderrun Bxg2 Kg1 Qf8!? Idk...
  61. bufferunderrun I mean in that line, not here
  62. rojazu (23) Bxf3 gxf3 and hope black doesnt see Rg1?
  63. bushie123 (26) Rg1 still a threat !
  64. rojazu and Qe8+ of course. white is doing well here to create practical chances
  65. bushie123 Kh8 and the white Q has to defend f3 .. mating threats to white ..
  66. rojazu Rg3 then?
  67. bushie123 Re1+
  68. rojazu Kg2
  69. rojazu white happy with a draw of course
  70. rojazu has to keep the majors on because the ending is losing
  71. bushie123 true, c2 guarded .. so .. nothing there .. maybe just pile up on f3 ..
  72. Akibart Re2+, Kg1 Qh5 maybe
  73. rojazu i preferred the white queen having access to bank rank squares - either directly or after a shift to say c6
  74. bushie123 (27) .. Rf5 .. pile up on f3 .. black Q is guarding g7/g8 ..
  75. bushie123 and e6 as well ..so no need to move that ..
  76. bushie123 oh, he wants to munch the pawns ..
  77. rojazu (28) Qg3 is nice. threat Qb8 and Qe5 if the rook moves... mate in 2 either case
  78. bufferunderrun 28.Qg5 seemed better
  79. bufferunderrun never mind
  80. rojazu then Qxf3?
  81. bufferunderrun yeah, of course
  82. bufferunderrun otherwise it wouldn't have allowed h6
  83. rojazu do we just play Rg2 cant see much else
  84. bushie123 Black is like 10 points ahead i'm guessing ..
  85. rojazu i still like Rg2. queen endings are notoriously hard to play, and both sides under time pressure
  86. rojazu f4 is a cheeky little trap move
  87. bushie123 (30) f4 .. offer a pawn for Qxe6 ?
  88. bushie123 e6 is guarded .. ?
  89. bufferunderrun oh wow
  90. rojazu aghhh Qxf4 Qd3+ Qe4!!
  91. bushie123 yep ..
  92. rojazu idea was to pick up the rook but it doesnt work
  93. bufferunderrun still Qe4+
  94. bushie123 yep. that's it ..
  95. bushie123 Qe4+ Rg7 Re1+
  96. rojazu best move now is to be a gentlemen and allow the mate
  97. bushie123 or you can just take and mate .. :)
  98. bufferunderrun gg
  99. rojazu class
  100. rojazu gg
  101. bufferunderrun yeah, offering that f-pawn was too optimistic
  102. greysensei I actually did not offer it, I blundered it :-)
  103. greysensei (11) just c3 smh
  104. greysensei At least I found (13) Kh1 best move!
  105. greysensei small moral victories
  106. Akibart Later you also had 16 Be4, I thought
  107. greysensei (16) Be4 interesting tactic
  108. greysensei (21)... I was calculating something like Rg5 Bxe6+ dxe6 Rd8+
  109. greysensei (22) I was considering Rxd5, but though that lost to Rxe8 Rxg7 Re8#
  110. greysensei That would have been a good try
  111. greysensei Rxd7 rather
  112. Akibart Right, we looked at that one and then Bxg2, Kg1 Qf8
  113. greysensei kudos to my opponent saw all my threats and didn't blunder material like I did
  114. RodGammon Thanks. Actually I did blunder material around the Combination in Move 16
  115. RodGammon At least according to the engine
  116. RodGammon Well, maybe not material. I do not understand the combination yet
  117. RodGammon Thought it was good but it was not
