At the first stage of the tournament you have to be a tight player, but better - "rock". You should not worry that you fold hand after hand - you take on your next steps. But to lose most of the chips at the beginning - a very serious loss. Therefore, the general advice is: Point Guard TT-AA + AKs. If you are in the first position, you can generally limit aces and kings.
Good advise if you want to get short stacked and either have to gamble your short stack or get blinded out .
1500 tornaments are usually turbo s and before you know it 30 min later your short stacked.
faster the blind levels = faster you must play , you simply cant afford to wait for AA KK.
See as many flops as possible in late position (cheap) , hit a good flop and double up your stack from a fish who cant get away from TP.
Steal from BTN almost 100% when first in .
Tighten up your range against maniacs , steal from rocks , don't
bluff fish/calling stations , value bet the donks.
ABC Poker for the most part.
