I get a completely different result using this calculator:
http://www.chillin411.com/icmcalc.php
current chips is if you fold
post chips is if you go allin and win
hand needs to win is derived from the % change in your equity if you go allin and win or lose this hand (notice that chip equity is irrelevant at this point)
Adjusting the slider on stove to get as close as possible to 56.1% equity on your hand, I come up with a range for villain of:
equity win tie pots won pots tied
Hand 0: 43.614% 40.67% 02.95% 177564353 12870560.50 { 66+, A3s+, K7s+, Q8s+, J9s+, T9s, A8o+, K9o+, QTo+, JTo }
Hand 1: 56.386% 53.44% 02.95% 233332046 12870560.50 { AhJd }
Conclusion: get allin if you believe his range is this wide, otherwise fold.
(Of course, this ignores other factors like being able to bully with a bigger stack, but I don't know how that could be quantified)
