A Game = Focused and paying attention to every table; taking notes and thinking how to exploit people. Planning hands and really trying to put people on correct ranges.

B Game = Usually doing other things at the same time as playing, giving up on too many pots and not really thinking about people's ranges deeply.

C Game = Playing my only hand and not really taking any notes or trying hard.

D Game = A brew of tilt and spew.

I'm good at noticing when tilt is affecting me and quit quickly, time to start doing the same if I feel myself playing my C game for more than 5 minutes.

Also whenever playing more than 2 tables I won't do anything else in the background so I can focus properly.
