A kill is an extra blind to be posted by the winner of the previous hand. Kill blinds are triggered by conditions: (a) one player wins the entire pot, & (b) the pot has to be a certain size (example: 10 big bets), (c) the betting structure increases for the hand with a kill blind (example: If you're playing $10/$20 with full kill the betting would go to $20/$40).
Note: (1)some rooms play a 1/2 Kill to cut down on the size of the kill structure. (2) the kill games tend to generate more action.
