It's fine))
I don't know about queens and kings, but when you have a short stack of 10-15bb, then you put all-in with any ace and with any pocket pair.
Well, if it's really bad with cards, then probably any connectors will do.
with a stack of 10bb or less, we already play mostly only pushing, of course, you can try to trap an opponent with AA, but this can end badly for us) especially in tournaments with knockouts
Rather depends a bit still.
Position is still important as well as type of table and players there are times I'd shove suited cards quicker then other times too. I'd be happy with anything 25% or better preflop really but also depends where in the tournament you are lol will not do this on the bubble ofcourse.
