[Closed] overcards

BB looks quite aggressive, but it appears he had good hands so far. The flop doesn't hit your range very well, so basically he can raise any made hand and any good draw. A calldown for showdown value is close however. You need a equity of

Equity > cost of calldown /pot at showdown = 2 /(5,2 + 2*2) = 21,7%

If he doesn't checkraise the 3 and not many 4, your equity could be higher.

You would have to fold the river on a club or on 7, 6, 5. Still, it's close because you have no good reads.
