My set detector is twitching a bit, but what to do about it?

Full Tilt No-Limit Hold'em, $1 BB (6 handed) Converter Tool from (Format: Bet The Pot)

Button ($269.50) 16/11/1.4 over 60 hands, flop AF is 1.7
SB ($99)
BB ($236)
Monkey ($123.90)
MP ($66.75)
CO ($101.35)

Preflop: Monkey is UTG with , .
Monkey raises to $5, 2 folds, Button calls $5, 2 folds. 5BB raise as someone posted out of turn.

Flop: ($12) , , (2 players)
Monkey bets $10, Button raises to $28

Call and play more poker OOP on the turn? I'll have $90 left in a $70 pot.
Folding now without an excellent read is bad I think. Moderate that with his nit-ness so far
Shove now or CRAI just about any turn?

Well his range is AA-22, 65-JT, AT+ preflop. On the flop to make that kind of play his range has to be narrowed to something like 44,55,TT,JJ,QQ,KK.,KQd,76d. It is good that you have the that knocks out possibilities like AdKd-AdTd. Against his lilkley range we are 2-1. I could also see soemone calling an ALL-IN with any of those hands so we are infact 2-1 against his ALL-IN range. If you call flop you cannot fold. Call and CRAI on turn.

I hate calling here, either shove or fold.
