Are you influenced by people's actions?
By the above I mean, if you are check raised, are you influenced by their actions to call?
Example :
You are involved in a pot with

(you have raised 5xBB from the button with SB BB + 2 limpers. SB BB + I limper folds, one limper calls)
Flop comes

jd qc
Limper bets 400 (4xBB)
You raise it to 1200. Limper calls
Turn comes kh
Limper checks, you bet 1200. After playing with his chips, counting out the 1200 and then counting what he has left, the Limper re raises all in for additional 3000.
Do you call? Are you influenced by the fact that he has counted his chips that way? Or do you put them on a straight, and fold your hand.
BTW the 3000 raise will be neally 80% of what you have left.
