Tilt is usually not much of an issue for me. First, if you understand that mathematically, bad beats and suckouts not only have to happen, they have to happen a lot more than say 5% of the time. Remember that all-in pre AA will lose to 72o 14% of the time. That's not 1 in 20, that's 1 in 7!! Now think of how often JTs will crack your AA. So suckouts and bad beats are totally normal. If you can get this fact into your bones and stick there, you will tilt a lot less.
For me, when I am feeling agitated over losing a big pot, I recognize the feeling. When I recognize this feeling, I just fold pre the bottom half of my range just in case my emotions lead to a bad decision with a weaker hand. Obviously if I am dealt a strong hand like KQs it would be a mistake to fold pre, I will still play. This feeling rarely lasts more than a couple of
hands. Then I go back to normal ranges.
