Middle set on river, two villains, poss straight/wet board ($5NL micros)

You need to put them on ranges and figure out your equity. If I'm not mistaken you only need like 28% equity to make this a call I think since you're being asked to call $2.15 in order to win $7.77 (.2767)

3bet pre is interesting. Reasoning?
reads on button are important, absent reads and bet-fold flop all day, about $0.75 should get it done.
