As a amateur, learning about poker, want to ask about some sort of hands i played yesturday.
Overall played 4 tournament yesturday, 25C entry - 45 sit n' go on Poker Star.
All of them i lost by All in on late stage of tournament, once on final table.
Important is, in all All ins i had better EQ, Call or shoved with QQ, KK, JJ and AJ, against loose players = all lost.
I'll show u guys one hand [QQ] where Im not sure, shall i call bet 2xBB on pre flop or I did good move but been unlucky.

Overll, I had similar situation with my other All in lost yesterday.
