Well I take a lot into account for every move done...When playing a hand I go to hand history against player, their table image, what my image is at table, what my goal is to accomplish with that hand, stack sizes vs blind levels compared to the raise and whats already in the pot (so your odds and equity) along with position...Also if what the player is doing makes sense (But that goes into my read onto the player or some will call gut feeling, which plays a huge role in my decision making)...I also take into account the stage of the tournament/sng that you are in..for example bubble play is different than mid stage play, etc.

Referencing to your tilting or emotional play, If I get sucked out and lose a huge pot usually I'll get up and go for a quick walk after the next hand or something just to clear my head so I don't play my next hand in a tilting frame of mind, to keep my loses as minimal as possible
