If I play a hand, get it in with crushing equity, it sucks but doesn't tilt me too much.
But if I play a hand in such a way that some of the money goes in on the flop, they catch a 2-6 outer on the turn/river, and then the rest goes in, I get the same tilt as before from the bad luck, but then I get the BONUS tilt of knowing that I put a lot of that money in drawing nearly dead.
Not a lot else to say...
