How did yuo play before? LAG? TAG? What about BB?
If BB showed before that he's not likely to defend his blind without a BIG hand and you've been playing TAG, yes. Otherwise - with your push the pot is 50+100+100+660=910 and it costs BB 560 to call so he's getting 1:1.62 on his call, and he'd be correct in calling with something like JT or any two broadway cards, really. I'd probably wait 3-4 hands and push with any semi-promising two when the blinds are on the mid-stacks (Above MP1, MP2 and CO) as calling and losing is disastrous to them. Current BB can take a hit and still be 1st or second in chips.
