(NLTRN $11) bottom-pair on paired board vs maniac

[gulon]

Villain is a lock me up in a padded cell maniac. He has called every PFR, every cbet, and has made pot-sized bets every chance he gets. I could see arguments for folding (he has a Q or something else that beats us), calling (we have a pair), or raising (probably all-in because he has been playing so maniacally).
