Hintless Puzzle #14



What the heck... this series is still going??! lol
Good puzzle; after a few minutes I think I have it, but can't be sure. That's what I always hated about these "hintless puzzles" - there's no way to confirm anything for days, because nobody is allowed to give even a proposed solution (or say anything related to the puzzle). It's really a terrible setup for a forum topic, if you ask me... it'd be better suited for an article or blog post.

Spoiler Alert ! Answer will be given down below.
Viktor Korchnoi vs Irina Krush, Gibtelecom Masters 2007.
Gibraltar's open has become a must for international experts. There's a huge prize fund, the Caleta Hotel venue has the best cuisine on the Rock, and the English control team runs the event smoothly.
Gib 2007 had elite grandmasters led by England's Micheal Adams, top women GMs , and the legendary Korchnoi, now 78, who defected from the Soviet Union then twice challenged for the world title. The veteran's penultimate round pairing with America's No.2 women player ended in farce when Korchnoi (White, to play) panicked at Krush's Rxd2 threat and went 1.Rf2 ? Why was this a blunder, and what should White play instead ?
Solution. 1.Rf2 ? Qxe4 ! forced resignation. If 2.Nxe4 Rd1+ 3.Rf1 Rxf1 mate. Instead 1.Rf8+ ! Kg7 (Rxf8 2.Bd5 win the queen) 2.Rxd8 Nxd8 3.Qxc7+ Nf7 4.Qxb7 puts White two pawns up.
