I think this whole TILT issue is often a bit of a misnomer.
When I get a bad beat, or FT/PS delivers one of it's stupid action hands or miracle rivers that busts me, I don't suddenly change my game mechanics and quite honestly I doubt most people change either.
In other words, your starting hand requirements don't suddenly change to the point where you are happy to raise with Q3o in 1st pos !!! In fact I'd bet that you mostly just carry on playing your same game. However, those deals, and beats do leave you intensely frustrated and highly cynical of the whole "system" in my view.
My response to that is to stop depositing money. I know that I am not tilting. I know that I'm still playing the same opening hands, raising when I should, getting chips in when I have what appears to be the best hand and so on. But none of that is enough and contrary to the earlier posting above, it's absolutely no consolation to know that you are making the statistically right bets when FT/PS continues to screw you and give the winning hand to the underdog.
We are not playing to feed our egos through the knowledge that we are good poker players making the right moves !!! We're playing for fun and to make some money as a direct result of our poker skills. Playing good poker and yet continually suffering busts and beats from silly dealing is in my view quite a normal occurance on these sites. Some people appear to be able to learn something about how all that works and make a slow but steady profit. So far I haven't been able to do that and frankly I'm not inclined to bother because deep down I know it's not poker but some other "system" I am learning. I want to be good at poker itself, not good at cracking a controlled "system" designed to keep people at the tables.
So, tilting for me results in anger and frustration but hinestly I don't believe it make me alter my game play. It just makes me want to stop playing. Which I have done. I only play freerolls
and play money now and even then my patience is waning because the same dealing occurs and I constantly think "what's the point?"
