Whats a free card?

Opponent is a LAG. Bad LAG. Should I be checking the turn in these situations?

are you betting the turn for value?

and would the flush completing induce him to bet or shut him down?

[Allinlife]

nah, this is a valuebet against LAG. nice bet.

[amoeba]

its just it seems the term LAG is overused in this forum.

There are different types of LAGS.

He was 67/34 with a pretty high AF aggression number.

I really don't care for this bet very much. Why do you like it?

Partly for value and partly because I wanted to get money in with top pair just in case he was on some type of draw too. I was planning on checking the river unless I hit a club if he called the turn.
