Nf3 (instead of 22. ... Rad8) threatening both 23. ... Nxe1 and 23. ... Qxe4. I think the best answer for white would be : 23. Rd7+ A) 23. ... Rf7 (or Bf7) fail to 24. Nf5+ winning the black queen B) 23. ... Kg8 24. Qxg6+ and mate next C) ...      Aug-30-14 M Dziuba vs A Ipatov, 2009    patcheck: The puzzle could start one full move before, after black played 28. … R5c8. Indeed, in this puzzle, after white 29.
