However, in reality, an individual antelope's priority is not to out run the lions, but to out run the slowest antelope. The lion's have no interest in expending any more energy than necessary, and as a result will always go for the easiest pickings on offer. As a result, when gauging your chances of survival as an antelope, your only concern is how quick you are relative to the speed and strength of other antelope - not to the ability of the lions.
This a very useful lesson to learn in poker, as it quickly teaches us that in order to win, you don't have to be better than the fastest and most skilled in a group, simply more skilled than the lowest. As long as you can outrun someone at the table, you will most likely be able to make a profit. Just as the antelope's primary concern is not outrunning the leader of the herd but the slowest one, so any poker player keen on survival primary focus is being more skilled than the worst member of the group.
Just as the old poker saying goes, if you can't spot the sucker at the table in the first thirty minutes, you're it, and this is as true in nature as it is at the card table.
This point also has much wider consequences on other areas of poker than table selection - particularly what games you learn. Someone with a wide knowledge of all poker games will be able to find games where they can out run at least one player at the table much more frequently than someone who specialises in just one game.
Weak poker players usually move between games regularly, trying their luck at new forms as they lose habitually at another. Players well versed in all games can follow these movements easily, where as a specialist can not, and once one game goes out of vogue the specialists are often left in a very desperate position as they struggle to find enough weak players to sustain them - a point fundamental to learning if you want to ensure long term survival.
