Battle of Blinds nearing FT.

We are ITM, 12 left out of about 110 runners. I'm SB, BB is a good well respected player, who played quite a few hands, but when he had to show, showed solid hands.

<font color="#666666">4 folds</font>, <font color="#CC3333">Hero raises to t1800</font>, <font color="#CC3333">BB raises to t16854</font>, Hero ????

If you say call, how bad is the fold, and vice versa? In any case, what's your calling range?
