Second time in the row in Deepstack AA fucks me up

The picture is from todays game. I flop trips, get him wher I actually want him and the donk calls all in w/ flush draw and only 1 card to come. And surprise surprise, of course catches his spade.

Couple days ago got busted out w AA against A6, after guy caught trips on river. Pushed all in on flop and he called it with middle pair-6 just to catch that river. Unbelievable.

Would stop playing for a while, but Summerchamps Promotion is coming up and I gotta play in that one. LOL.
