5/10 NL - Do I felt TPBK here?

[Cue-Ball 66]

SB has $310, BB has $900, hero covers.

Haven't been at table overly long, but have been reasonably aggro, raising a lot and 3-betting twice in the last round and taking it down pre both times. SB is just a donk short-stack, min-raises lots of crap, donk bets a lot. BB has only been at the table a few rounds.
