It's the holy grail of poker, really.
The "whale" - a big-moneyed, amateur poker player with a bottomless bankroll, an eye for the gamble and next-to-no sense of what's truly happening on the felt.
Ask any poker oldtimer about the days a big-time whale rolled into their town and you'll see a gleam in their eyes likely only matched on their wedding day(s) or the birth of their children.
Or, likely, never matched at all. Life outside of poker ceases to exist when a whale surfaces and any poker player with a pulse lives for a seat in the game - if only for a few hours.
Lifetimes bankrolls can be made in one epic session, and a lifetime of stories too. In honor of the Discovery Channel's now-infamous Shark Week, guest blogger James Guill takes a look at some of poker's biggest-ever donators in a five-part series we've dubbed #WhaleWeek.
