Back-shove
A back-shove is an all-in re-raise made by a player who first called.
The simple explanation
A back-shove is an all-in re-raise made by a player who first called. You call a bet, someone raises after you, and when the action comes back, you move all your chips in. It is a back-raise with all of your chips.
A closer look
Because the whole stack is at risk, a back-shove usually means a very strong hand or a strong bluff. The player who called first has shown less strength, so the shove can be surprising. The player who raised first must decide whether to call off his stack. As with all-ins in general, the shover cannot be pushed off the hand once the chips are in.
A practical example
A player calls a bet and an opponent raises. The first player then pushes all in.
