Flop check raise w underpair multi-way pot

[DVDA4life]

Preflop 3 better is a competent TAG who has 22/16/1.7 stats with a WSD @ 34%. The original raiser was a TAG and the other two were fairly loose and agressive.
Do I get this heads up with the preflop 3 better when he has unimproved high cards enough for this to be profitable?
