DefinitionA raise is an action that a player can make when confronted by another player's bet. To raise means to bet over the amount wagered by your opponent. The number and size of raises per round may be bounded depending on the house rules. Usually, 3 or 4, or less often 5 raises are allowed per betting round. A raise that follows an opposing raise is called a reraise.
Complete and Incomplete RaisesIf a player raises and that puts him all-in, i.e. he bets his whole stack, but does not have enough money or chips to make the minimum raise, then his raise is called incomplete or irregular. Depending on the house rules, such a raise might only be called incomplete if it is less than half of the minimum raise amount.
An incomplete raise does not reopen the betting, i.e. players who have already acted in the betting round cannot raise again. They can only call the incomplete raise or fold.
Player A bets $4.
Player B calls.
Player C has just $5 remaining and goes all-in
The minimum raise is $4. Player C must first pay $4 to see player A's bet and then has one remaining dollar with which to raise. His raise is incomplete since the smallest complete raise is $4. Players A and B can only increase their wagers by $1 or fold. They cannot raise again since they have already acted this round.
