Late Registration

Also known as: late reg, late-reg, reg close

The window during which players can still buy into a tournament after it has begun, ending at a set level.

Late registration lets you enter after cards are in the air, up to a published cutoff (e.g. end of level 9). By the time you sit, blinds have risen and the average stack — measured in big blinds — has shrunk, so you start shallower than the nominal starting stack suggests.

Whether to late-reg late is an EV question. The upside: you skip the deep-stacked early levels where edges are smaller and variance is high, and in re-entry events you can fire directly into a soft, shallow field. The downside: entering with 25-30bb caps your postflop edge and pushes you toward push/fold play almost immediately.

The break-point is field softness versus your shallow-stack skill. A strong short-stack player late-regging a soft field with 30bb is usually +EV; the same entry into a field of regs averaging 18bb is often a thin or losing proposition.
