My Arse is pretty sore!

getting absolutely bummed at poker in the morning, and getting slightly pissed off with it.
$3500 tourney today get my money in with AA v AK for a 16k pot
the board read A3QJ....T that was nice... then on the $5000 re-buy short stacked with 9k in chips a guy maks it 1600 to go with blinds 400/800, me being in position on the button decide to call to see the flop, which comes 5T5 quite a nice flop, he bets 1600 again and i push for about 6.5k more. the guy calls and flips over......
AA? KK? QQ? AT? nope A7 and proceeds to catch his (2outer as it turns out) on the turn. the tournment i am curently in ive decided just to push all in with every premium hand, because in these tourneys you WILL get called... we'll see how tis tactic works
