Cappalletti's idea of betting high hands when you get a high flop works better when the high flop does not contain an Ace. The Ace will hit all the low hands, giving them at least a pair and possibly two pair. This greatly reduces your chance of picking up the pot. The Ace also makes it not an all high flop but a one low card flop. So you will get called by people trying for a backdoor low.

I would check this flop. If the position of the Ace and King were switched (Ace in your hand with a K T 9 flop), I would be more inclined to bet.
