What is a "KILL" pot?

In a kill game of Texas hold'em, if a player wins two pots in a row, the stakes are doubled for the next hand. In a half kill game, the stakes are increased 50%. The player who met the kill condition must post a blind equal to the new lower limit bet size. This is in addition to the normal blinds posted for the game. If the player who met the kill condition is supposed to place the small or big blind, the new blind bet is placed instead of, not in addition to.

In some casinos, the killer acts last after the blinds; in others he acts in normal turn order. Limit Texas holdem rules are the same as fixed limit Texas hold'em rules, with the exception that the bettor may bet any amount between the stated minimum and maximum bets. For example, in a 10-to-30 spread limit Texas holdem game, a player may bet any amount between 10 dollars and 30 dollars. In addition, all bets and raises must be greater than or equal to the previous bet or raise, with the exception of a player that is raising all in. If a player does raise all in, and that bet is not greater than or equal to the previous raise, then the door is not opened for the original raiser to reraise.

I've also seen it played in Omaha 8 where if the winner SCOOPS the pot (wins both High & Low), the next hand is a KILL pot by the winner of the scooped pot.
