Final Pot: $33.50

Opponent is 23/8 with agg of 3/2/1.5 over 240 hands

I feel like he's only doing this with AQ/KK/hands that are scared they're beat...Because its cheaper to bet/fold than it is to check/call or c/r

The problem is i have no balls

Should i be making a play here?

**edit**
Im an idiot and thought i was in full ring NL/PL

Someone move please?
