Rybka and Stockfish (and Komodo also) appear to prefer b6. However, my own Critter runs stubbornly cling to the alternative move. So I am going to analyze this sequence at long time control:

Here is my analysis from last night. I may need to run this on my fast machine at 8 to 24 hours to get a meaningful result.
