im trying to find the real purpose of a bet like this.

you raise pf standard w/ 78s. get one caller with position on you. flop comes A A 7. typically, i fire one off here about psb. of course i fold to a raise. am i ruining any value here? do i really blow 99 out? do i really fold off anything better here, and/or get a caller out of something worse?

the reason i do it is to take the pot now. if the T comes on the turn, i certainly cannot even call most bets at that point, essentially ruining any reason to avoid betting on the flop in hopes of extracting any value that may be there.

do you bet here and try and take it when you can, but shutting down to resistance? or do you check/call until an over card hits? what is your reasoning, typically?

what if we had 99 on that flop? does that change anything?
