PocketFritz3 with Hiarcs 12.1 engine needs just 1min 23 seconds at D=10 to select b5 with a 1.05 advantage for black.It took me a while to see that 2.cxb5 runs into 2..Nxe4! 3.Nxe4 Qa4!The older version of Hiarcs 9.7 for Palm does find it after 21 minutes.PocketGM with TogaII 3.1.2se engine prefers g5 with a 0.7 advantage but finally finds b5 after 20 min and D=14.

I guess Rybka WinFinder 2.2 is the fastest in this position - Just 2 seconds to get b5 and stick with it!
