Pot Odds on the flop

[AcemanBR]

No-Limit Holdem $ 1/2 blinds.

I limp in on the button with 7 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] after 4 other people.

POT = $10

The flop opens: A [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img].

Small blind bets $8 and 2 people call.

POT = $34.

Well... I have a straight draw. I have to call $8. Pot odds are 23,5% (8/34 = 0,235).

I call because I have 8 outs, 32% to make it on the turn or river.

Right?

I don't think so. Because, if my straight don't come on the turn, I will have to pay one more bet round to see the river card.

The numbers I had to think about on the flop were: The odds of my card come on the turn are 18%, so I should not call with 23,5% pot odd.

The 32% should be used only if I went all-in to call. Then I didn't have to think about the other bet rounds.

I am not considering implied odds here.

That is the right way to think?
