re: Poker & winner takes all tournaments
In these formats, ICM and "staying alive" take a weird turn since... well you need all the chips in order to cash. Of course it all depends on the table. Generally what you want to do is steadily increase your stack, but that is really hard to do in practice. So you have to play this more like a cash game and maximize your chip EV. Play like you would deep stacked in a cash game in the early stages and then play like you would shorter and shorter stacked in a cash game as the blinds go up. There are many tricks to deep, mid, and short stacked cash game play -- head over to the cash game strategy to learn all about it!
But seriously, these things have really high variance, you're better off playing just about anything else.
