A tournament is a different product from a cash table. On a cash table, the player buys in for a stake, plays a hand, and either wins a share of the prize pool or pays the cost of the hand. On a tournament table, the player pays an entry fee, plays a sequence of hands within a structure, and finishes at a position on a single ranking. The structure is what the rest of this route is built around.
Three structural decisions define a tournament. The first is the table size: how many players sit at each table, and how many tables run in parallel. The second is the round structure: how many hands are played at each table before players are reseated or eliminated. The third is the payout ladder: how the prize pool is divided across finishers, and where the finishing line for a payout sits.
A fourth decision sits on top of those three: the registration window. A tournament that closes registration at the start has a known field. A tournament that allows late registration has a field that grows during the early rounds, and the prize pool grows with it. The choice is structural and it changes the arithmetic of whether to register early or late.
Why the structure matters
The hand-by-hand decisions are the same as on a cash table. The cost of a discard, the read of the open pile and the choice to drop do not change. What changes is the weight of those decisions when a single bad show is the difference between a finish in the money and a finish outside it. The structure determines that weight, and the rest of this route is about how to read it.
