Italian Game: Giuoco Pianissimo
  1. Leverkuhn looks Black had the chance to win a piece with 12...b5!
  2. Leverkuhn other than that, fairly placid Four Knights
  3. Leverkuhn Black is still quite a bit better after 20...Qc7 due to White's poor coordination
  4. Leverkuhn When you don't know what to do, play ...g6 and ...Kg7
  5. Leverkuhn Demeter has the Kramnik spirit, though of course there were better plan available
  6. Leverkuhn such a shaky move, but 22...Bxc4 is still there
  7. Leverkuhn crazy to play 21...Bd5 instantly
  8. Leverkuhn 22...Bxc4 was not spotted, unfortunately
  9. Leverkuhn now the pin remains, and it can no longer be broken with ...Bxc4
  10. Leverkuhn after 23.Rd4 Kg7! 24.Rfd1 Bxc4 25.Rxd8 Bxb3 26.Rxa8 Bxd1 27.Nxd1, Black somehow avoids material loss
  11. Leverkuhn instead, White has allowed en passant
  12. Leverkuhn it could be a similar line actually, though the tactical importance of dodging out of Rxd8 being check is far from obvious
  13. Leverkuhn I just realized that the exchange of pawns means Black wins with ...Re1+ at the end of my line now
  14. Leverkuhn so maybe more relevant is 24...Kg7 25.Rfd3 Bxc4 26.Nxc4 Re1+!! 27.Rxe1 Qxd3, again miraculously avoiding loss of material
  15. johnsb50 I am lacking sleep etc, but why did black gave his queen there ?
  16. Leverkuhn she thought she would lose a piece after Rfd3, intensifying the pin
  17. Leverkuhn chose to give queen for rook and exchange instead
  18. Leverkuhn I think Black could have avoided losing anything with extreme tactical cleverness, as explained above
  19. Leverkuhn it's far from hopeless though, as White's 26.Bxf7+ made things harder for him
  20. Leverkuhn 27...Rd2!! threatening mate and the queen is still stuck defending f7
  21. Leverkuhn oof
  22. Leverkuhn the king was let out
  23. Leverkuhn okay 28.Kf2 Rb1, White still has something to figure out
  24. Leverkuhn but 29.Qc2! Rxb2 30.Qxb2 Kxf7 should be winning
  25. Leverkuhn going with she because of Demeter's handle; hope it's correct
  26. jackbwfc White's looking for pawns, have they missed Rd2?
