具体牌谱没了简单叙述一下。  0.25/0.5    Hero  $7.5  CO      VILAIN  $21  BTN       (vilain plays like 20% VPIP for several rings, no any other idea of vilain before)
1 limper,   Hero dealt   JJ,    raise to 0.85,    Vilain  RR to  2.25       all others fold.  hero calls.
Pot  $5.1
flop   T  8  5   rainbow

Hero??


In Real:
Hero  bet out $3      VILAIN  RR  HERO ALL IN
HERO CALLS

comments pls.
