Poker Glossary - V
A bet made to try and get the last few possible chips into the pot - usually made on the river.
A bet declared orally, rather than made physically - for example "I'm all in" rather than actually pushing your chips into the middle.
A hand that has been mis-dealt may be declared "void" and re-dealt - for example if a dealer accidentally exposes one of the hole cards whilst dealing.
