I said overbetting the pot here destroys your fold equity because I believe such a severe overbet incites many calls. I agree that it sounds counter-intuittive.
The opponent must be capable of a fold. That is the key. Many people see such a severe overbet as a bluff or a weak hand that is afraid to see more cards. Often I find a fish on a flush draw here.
I do agree it is great to set up your table image, but at 25NL I have few opponents who remember my table image after 5 orbits.
I like a simple call here as I feel it isn't worth the varience to fight this hard over $6-9. If I do raise, it would have to be all-in. I would hate to raise $18 and then see a blank turn card. Then what, now I'm screwed for pot-odds. I don't hate the all-in, but I believe there are better situations to push with a OESFD. I smooth call here.
