<font color="#CC3333">BB bets t50</font>,
<font color="#CC3333">Hero ???</font>
At this point Hero has t640, BB has t1615, pot is t375.
BB got his chips by pushing over Ax w/ AK a few hands earlier. Not sure if this matters, but earlier in the game, BB took a small pot off of Hero with a checkraise on a rag flop after calling a PFR.
What is hero's move here and why?
