AA vs KKx flop

[bconway6]

I Raise the flop. That way if he has a 9 and is getting aggressive with it he’ll fold and you’ll win the pot right there. If not, you’ll know by a reraise if you’re beaten or by a call you can probably get a free river if you want for a cheap showdown. If villain bets the turn when a blank hits then you’re probably beaten also.

The problem with keeping others in is that it is unlikely to work. That is a very intimidating board. It is unlikely that anybody is going to donate anything else to the pot. The cost of not protecting the pot is greater than the possibility of extra callers.
