PP 20+2 middle stage aggression

Maybe i just got coldcarded today, but i'm losing confidence about my aggression, when entering level 4 with 6 or 7 players still left. Maybe you can comment my "play" in the following consequtive hands

BB50, 7 players
53o in the BB with T735, fold to MP1 Raise
BB100, 7 players
73o in SB (T685), fold to UTG Raise
T8o Button (T635), openfold
74o CO, openfold
J9o UTG+3, openfold
BB100, 6 players
J5o UTG+1, openfold
Q9s UTG, openfold
83o BB, fold to SBsteal
T5o SB (T535), fold to Buttonsteal
96s Button (T485), openfold
K8o CO, Allin, no callers
BB150 6players
72o UTG+1 (T635), openfold
62o UTG, openfold
85o BB, fold to UTG Raise
Q3s SB (T485), fold to UTG+1 Raise
J3o Button (T410), pushed and lost against A9o

Some openfolds might be a little bit weak, but i cannot see any definitive raise. Any thoughts, or should i just learn to get better cards? /images/graemlins/smile.gif

When K8o is your best hand out of 17, well yeah, tip the dealer...

I dont know how many people left when you busted but you were probably shortstack so openpush any two on button is ok. You might want to wait next hand since you get around 80% chances of being dealt a better hand but maybe you won't be able to openpush..

So, blah.. not much you could do i think..
