I'm a little aggresive early in a tournament, 5BB or 6BB; never cold calling preflop always reraising and folding if someone shoves. I wanna see clear how much does people care for their
hands. This will give me a good estimation for betting on the flop. If i get reraised on the flop i fold. But usually if no A or K on the flop, everyone folds. I even bet the flop if there is an A or K.
In later stages i shove instantly if there is no raise preflop, from any position, but only if i'm under 10 BB.
I could write more examples but these are yhe main situations.
