Now Houdini says it's a win!
I wonder if by backtracking it is possible to find the White's "wrong" move (if any...)

I tried, but it's a long process... 8-)

You probably mean Black's wrong move.

I don't have a sudden "black's wrong move", it has been steady improvement, squeezing centipawn by centipawn with Persistent Hash (avoiding known drawn positions and going for positions where known won lines existed, I'm glad this seems to be working!) Now, let's see if the game is actually won!

Yes, it's my main engine in all my games. I couldn't have saved some losing games without Persistent Hash, and I couldn't have won some without it.

Now I have a conflict of interests for Rybka 4.1, do I really want a fully working Persistent Hash for it? Considering my opponents would also have it and I'd lose my edge? Hard question! :)

I would rather have your techniques than ph as advantage. I am running quite low on time as my travel schedule continues to ramp. Let me know if my pace is an issue.
