Played a $22 no mistakes but just lost a flip and then used a $109 tournament ticket where I shoved 15BB with 99 from mid position only to be called by JJ on the button.
I did call an all in shove with KQo for half my stack and surprise surprise found myself dominated. It’s either a flip of domination nation so not +EV.
I would suggest open shoving with any pair at any position, strong aces in early position, weak aces in late position.
Also if everyone folds around to you on the button or small blind then shove any two cards. If you get your stack above 20 bb then start playing how you would normally
