Hi.
Preflop: What are the stats of the fish? I would often prefer flatting here to let the fish into the pot - Our main profit comes from the fish and we want to play as many pots as possible vs the fish.
Flop: Our hand is not quite strong enough to c/c in my opinion, we could c/c with stuff like KQ and KK but maybe with JJ you can either just bet and try to take down the pot immediately, or check and hope your opponent plays straightforwardly and doesn't bet. If he bets and if we think he is honest we can just c/f.
I actually do not mind both plays.
Thanks.
