When a short-stack moves all in and you have him comfortably out-chipped, your decision is usually straight-forward. You consider what range of hands he could have, gauge the likelihood that your hand is best, do some quick pot-odds math, and either call or fold.

At every stage of a Multi-Table Tournament, your stack size relative to the blinds should be crucial to how you approach different hands and situations. You may start a tournament with anywhere from 50 to 500 big blinds, but by the final table, the average stack is often between 25 and 40 big blinds. When deep-stacked, you can afford to make a lot of speculative raises, see a lot of flops, and make plays at pots without risking going broke. However, when you have about 20 big blinds or less, you should be looking primarily for favorable situations to get your money in pre-flop, oftentimes shoving all-in over the top of a raiser you suspect to be stealing.
