Usually this decision is made with the top spectrum, limp on the preflop, and regardless of the situation, push on the flop. I very rarely call BB and then for the moove of float only. cold call bb it's fish moove.
It depends on the tournament structure ,, on the stage and your stack size. Usually play normally limp if the tournament stage when all players have short stacks. Or if the size of the stack allows you to go to the bank with 10% to 15% of your stack. In other cases, or fold or all in.
