100nl set, your thoughts?

[TheJS87]

UTG is normal taggish (probably slightly weaktight) multitabling regular on stars 100nl, hes most likely a winning player.

He most likely knows me and probably thinks of me in a similar way, if he has pt he would know my stats are 12vpip and 7pfr, im pretty sure he knows im capable of raising flop like this with a draw.
