depends, esp with SB in villain might be raising for a free showdown with a small pair and raising a Q seems reasonable as well

if you feel strong about your read that villain would only call those hands down, I think you should also discount the possibility of him raising the turn on a draw

also, a lot of drawing hands would raise the flop

it's close, but I see value in calling down to see what villain has for meta game purposes
