Set monotone flop 2/4

How bad is this? Do i push flop or turn here? Or is it ok to just close your eyes and call down?

SB is bad and has been playing fairly aggressive, but not overly so. UTG+1 is new to the table, and so far has been solid.

Button: ( $498.92 )
SB ( $461.90 )
BB Hero( $741.80 )
UTG ( $435 )

When SB checks the turn, I push here.
