Who this is for
Whoever is organising the Friday game: how to split the chip set, when the blinds should go up so everyone is home by midnight, a clock the whole table can read from the sofa, and how to divide the prizes fairly if the last three players want to stop. And players who want to understand the numbers behind the game: how often a draw comes in, what a bet size asks of the caller, why aces are not as safe three-handed.
What is different here
Every page names its method and says where it stops being reliable. The tournament clock works out the time from the real clock instead of counting ticks, so it stays right in a background tab and after a reload. The equity calculator enumerates every possible board exactly whenever that is fast enough, and says plainly when it is simulating instead, with the margin of error. Where there is no single right answer, as with payout curves and chip splits, the page says what choice it made and why. The full list is on the about page.
