BB is according to Pokertracker a tight passive player with a 8.5 WPIP/1.4 AF/6.3% PF. I would like to think that this would affect my decisions but I really don't know. Anyway the flop is pretty damn good for me so I raise. BB raise on the turn tells me that I may need help but still has the odds to at least call. River helps me but maybe not by much. Is this an obvious call?

Thanks
