With no history on the player i like a check back on the flop. A check raise really makes it tough to play even with position. there are also a ton of cards which you have to fold to on later streets if u get called. Ive seen some coaches on stox poker take a bet fold line in this spot but they were oop. Given the stack sizes as well, id like to get to showdown with this hand and try and play a small to medium size pot and maybe pick of some bluffs on the way.

bet call in your spot would probably be the best line. bet fold is a bit too weak ip. id probably be folding a lot of turns depending on sizing and the turn card. if turn goes check i think checking back is probably best.
