Stats: BU 27/10/2.8/wts28/wsd56/hands98/AF flop2.1,AF turn 2.4,AF river 3.6,calls many raises preflop and many cbets.
What if:
-same situation ,but BU raises on flop,hero calls and BU bets turn .Can hero suspect bluff and continue with J J as the best hand?How to continue- push turn or c/c?
-same situation ,but hero in position(BU),villain in CO and he donks on flop.Is raise for information and protection OK here?If villain continues on turn hero folds?
-What are bluff opportunities in such hand?
