re: Poker & $2 NLHE Full Ring: it's bad beat or a wrong game?
Middle pairs here highly likely calling hands, a set is possible and the min raise is so small its just a pot sweetner and alarm bells should be ringing,, if you were bluffing
in his shoes wouldn't you raise bigger on the turn to get you off the hand.
Call the min raise (pot control 1 pair hand) and and see what he does on the river, call up to a half pot bet on the river. (Easy in hindsight of course. my mantra never go bust post flop with a 1 pair hand)
