Yes, there are some very wild variations in this position.
Nf5!! indeed is best, it leads to a Rook ending that is probably won for White.

Re: test position: Bubir-Knobel, ICCF Olympiad 17 Final 2009
Hard to know how much of this is down to SMP, but H2 gets the solution with a fewer nodes, but needs more nodes to give a high eval. (is that comment a valid way to measure progress?!)

Re: test position: Bubir-Knobel, ICCF Olympiad 17 Final 2009
29. Qg3! in the variation with 27...Kh8 is a nice find in itself too. Definitely not easy to judge. I just wanted to show that it is winning, with the latest build of Rainbow Serpent running on a lowly Athlon. But I don't think it can find 26. Nf5 yet. It does however have a slightly asymmetrical PV now, only when searching the first Rootmove, inspired by Chess Genius and Ed's stories about "Weinergate" and the "Ossi papers" 
. I still have an MS Dos computer somewhere that has Chess Genius on its 20 MB hard disk, but I'm not sure it has survived several winters in storage.

are, by definition, not smart enough to debug it.
