What a push is, and how it settles here
A push is a bet that lands exactly on its line. Nobody wins it and nobody loses it: the bookmaker returns your stake, and you end the bet with the money you started it with.
When it can happen
Only when the line is a whole number, because only a whole number can be landed on exactly.
- A total of 8.0 and the game finishes on exactly 8. Push.
- A spread of −1 and the side you backed wins by exactly one. Push.
- A total of 8.5 or a spread of −1.5 cannot push. That is what the half-point is there for: it removes the tie.
Some books write whole-number lines as "0.0" or "PK" and some split a stake across two lines. Those are your bookmaker's conventions, and they decide what your bet does — not what your day does.
What it does to your counter
A push is one of the void reasons, so the counter does not move. The day is neither delivered nor spent: it is recorded as voided, published with the reason, and the following day carries on as normal.
The reason it is treated as a void rather than as a loss is simple. Your stake came back, so nothing was decided — and a day where nothing was decided is not a day you should be billed for.
