I have been getting alot better in these tourney and have noticed that midway through a tourney when it seems like i need to make a big move i go all in on like AJ  A 10 or so me other upper hand s and it usually ends for the worse sometime by better hands which i understand and alot by smaller runners or weak pairs.. The question is do i need to practice more at reading patterns of previous hand and is there a system of pretelling what may hit the flops?
