2 limpers to Hero im MP (1700) with A
Hero limps Sb completes BB checks. Flop 10
SB (1200) bets 20. TAG player. Has anything from top pair to nutz. UTG (800) makes it 75. TAG. very tight. few showdowns he showed 3rd nutz or better. I put him on a set or straight. He 3bet flop one time with middle set in a previous hand. Folded to Hero? Fold, call, or reraise?
