sometimes i go deep in tour, get prize position then some perfect card comes, all-in twices and
Ending with nothing.
Question is when you get good position, should you play with uncertainty of all-in, you can get top prize but oppostie side, you even can not get $1!!!!
What you always do in this situation?

When you are in position from the prizes, it is correct to go for all the chips with aa. This is very difficult to do.
