I'm new to this site. Have less than 200 hands at it. Just started playing 6max. I've played 99% of other ring at full ring.

Villian is 41/30 over 17 hands. This hand happens after about 2 orbits. This guy has been raising all over the place and has been aggressive after the flop.

Table "Redeyed" Seat 5 is the button.

I want to conceal my draw here. I want it to look like a 25NL I've got a set play. I know he is going to call. So the question is, did I kill value or is that offset by concealing my hand?

Normally I would make it $30-35 to go here.
