Yup, get it in. But I would just shove instead of making a smaller raise. Someone is likely on a draw. Stack sizes are awkward if you raise less than all in.
Let's say you make it $100 and get called by both villains. The pot is now $315. Do you fold on a
turn when V2 puts in his last $80? What about on a jack turn? Or a Q or 7, completing the OESD? Just get it in on the flop.
