ITM means In The Money.
I think 11,000 with 1,600-800 blinds is already short.
Final table is kind of a special situation, but depending on the structure you usally want to get top 3.
If the play on the table is very crazy with lots of action then you might want to try to find a playable hand, but if everyone is just waiting each other out, then I would say go for it.
Gamble, push, steal blinds. Sure you will be a dog every time someone calls, but you will add more than 20% to your stack every time they fold, and even if they call you are very seldom without chances.
If you just wait and wait you might manage to get 7th or even 6th, but what good is that when the real money
usally goes to the winner?
