Thanks for the input all.

I was mistaken in how i played the hand, as I just rewatched it. Since it was the last of the day and I was tired I shoved the turn as a spew and the river came as a 4. What a terrible play, not sure what I was thinking, as there wasn't really any value in the shove as he was pretty much committed to call the last 0.47 or whatever after raising to 0.90, and he probably wouldn't have made a raise like that without a hand that has showdown value to my AKo.

Woups. When you make plays like that you know it is time to take a break for the day. In any case, lesson learned and thanks for the advice.
