Benoni Defense: Benoni-Indian Defense
  1. glbert go hicetnunc!
  2. arbisto what was wrong with 18...Qxd5
  3. arbisto i meant 17...Qxd5
  4. juped I agree. Think Qxd5 worked
  5. arbisto white wins f7 but i couldnt see continuation for w
  6. ahmt92 white wins also c4 pawn
  7. InfernalJumble Rxf7 Kg8 and Bxc4 maybe
  8. InfernalJumble then if the knight moves there are discovered checks
  9. arbisto ok that makes sense
  10. arbisto i thought Nxf7
  11. arbisto but Rxf7 seems stronger option
  12. ahmt92 why Qd6 instead Nd6?
  13. arbisto you mean why not?
  14. ahmt92 yes why not
  15. ahmt92 it seemed strong to me
  16. arbisto well this developes with tempo
  17. arbisto and qd6 does what?
  18. arbisto aahh ok
  19. ahmt92 how can white prevent mating threat
  20. arbisto Bf4?
  21. InfernalJumble or h3
  22. ahmt92 if Bf4 then Qxd5 Qxd5 Nxd5 there is no Rxf7
  23. ahmt92 yes h3 maybe
  24. arbisto that sounds fair
  25. ahmt92 but i think this was better though h3
  26. arbisto if not careful, black may trap his dsb as well
  27. arbisto tactic time!
  28. ahmt92 Hmm, This seems very dangerous
  29. arbisto too many threats
  30. ahmt92 he needs to calculate Rxh2
  31. arbisto ahah
  32. ahmt92 but that doesnt work i think
  33. arbisto too fast
  34. ahmt92 lol
  35. ahmt92 this is another interesting tactical idea
  36. arbisto wauw
  37. ahmt92 prevent to Bf4
  38. arbisto ooh
  39. arbisto such an end
  40. arbisto !
  41. ahmt92 Guys very good game
  42. ahmt92 for both sides
  43. InfernalJumble gg
  44. arbisto hicetnunc made similar knight intervention tactic to you ahmt
  45. arbisto can you remember?
  46. ahmt92 haha yes
  47. ahmt92 i didnt see again
  48. arbisto knight intervention and discovery
  49. juped Gg
  50. arbisto must be quite annoying
  51. arbisto it wasn working it seems
  52. ahmt92 yes it easily can be missed
  53. arbisto Rd5!
  54. ahmt92 but maybe white could have played Be3 instead Kh1
  55. arbisto i didnt get the last move of white
  56. arbisto he played so fast and get mated
  57. arbisto he may have seen rd5 if spends more time
  58. ahmt92 Rd5 means Rd6?
  59. arbisto sorru
  60. arbisto yes
  61. arbisto rd6
  62. arbisto i mean Kh3 is a resignation
  63. arbisto he resigned without thinking
  64. ahmt92 yes, white had still material advantage
  65. ahmt92 could have given some material
  66. hicetnunc yes, Kh3 is brain slip :-)
  67. arbisto well played hicetnunc till there
  68. hicetnunc I have to play 23.Rd6 and see what happens
  69. arbisto felt bad
  70. hicetnunc @arbisto : 17...Qxd5 18.QxQ NxQ 19.Rxf7+ Kg8 20.Bxc4 Bxg5 21.Bxd5 Bxc1 and 22.Rxc1 or 22.Rf3+ first is what I had in mind - I think black is
  71. glbert good game.
  72. hicetnunc busted in these lines
  73. arbisto yes I saw that later
  74. ahmt92 but after that you were still good
  75. arbisto i thought 19. Nx7 you re planning
  76. hicetnunc no, I had planned the line I played - I just missed Nf5+ interception
  77. arbisto you made the same tactic to our board-1 :)
  78. ahmt92 yes you played Rxf6 very fast
  79. hicetnunc this was my line
  80. hicetnunc I had a blind spot, I though N anywhere Bf4 - except Nf5+ of course :-)
  81. arbisto Rd6 is not easy to spot though
  82. hicetnunc well, you can find it by elimination as both Kh3 and Kh1 lose immediately
  83. arbisto yeah
  84. hicetnunc Maybe I gave black too much counterplay, but that was fun :-)
  85. arbisto benoni setups always get exciting games
