Cash Game on Pokerstars 10c/25c
I get dealt 88 UTG and raise it up to $1. I probably should have made it $1.25 as there is a dead blind in the pot but didn't notice that (possibly playing too many tables).
I end up getting called in three spots. flop comes a scary looking

. I have hit a bottom set but the board is very wet. UTG checks so I bet $3 into the pot (too small or about right?). I then get raised to $7 and the player who originally checked to me cold calls. Action back to me with bottom set?
They can't have AA or KK as they would surely have reraised preflop. it can't be tens or jacks either and draws look unlikely. Should I be folding my set here?
