One minimal-skill method that occurs in non-casino and casino games happens when a player who has folded appoints himself the tender of the pot, stacking chips, counting them, and delivering them to the winning player.
Another minimal-skill method is going south (also known as "ratholing"), where a player covertly removes a portion of his chips from play while remaining in the game, normally in order to preserve the winnings as profit, or prevent a major loss in "big bet" games.
