Playing minimal stacks (10BB or less)
Whenever I have a stack of 10BB or less, I do look to get it all in, but not with just any hand. I wait for a hand that would be semi-playable, such as 9Ts or KJo. You can't wait forever, especially if ante's are involved, but you do need to make a statement to the table that you still have fight left in you.
A second strategy is determining to go all-in preflop, but then dividing your stack among all the streets, such as 3BB preflop, 2BB flop, 2BB turn, 3BB river for 10BB total regardless of what cards come. If you're playing against a good player, this is meaningless, but if you're lucky enough to get a mediocre player or even a tight player with a mediocre hand you can actually scare them off the pot with bets like this.
