[Mike Haven]

you were a 5:1 dog on the flop with 12:1 odds that is an AUTOMATIC call.

I am not arguing whether you should or should not call, but your figures are wrong, bunky.

On the flop, the odds of catching his inside straight draw were 43 to 4 or 10.75 to 1.

If he hadn't made it, he would have had odds of 42 to 4 or 10.5 to 1 of catching on the river.

I believe you are thinking that he had 5 to 1 odds of catching on either the turn or the river.

You can't use these odds unless you are all in on your flop bet and don't have to put more money in on the turn if you miss.

(You could maybe use the 5 to 1 odds if you added the flop and the turn bets together. For example, let's say there is $12 in the pot in a $1-$2. At the point of the flop bet you are getting $12 to your $1, 12 to 1, for your 10.75 to 1 draw. You could maybe say you were getting pot odds of $12 to $3, or 4 to 1 for your 5 to 1 draw, if you were absolutely certain that there would be no raises on the flop or turn bets; but this would be a risky (gambling) assumption to make, and we don't want to gamble, now, do we?)
