In poker, the term “chip up” refers to the process of exchanging smaller denomination chips for larger ones, typically when the value of the chips on the table increases.
This is done to make it easier to handle larger amounts of chips and to reduce the clutter on the table. For example, if a player has several $5 chips and the blinds increase to $10/$20, they might exchange their $5 chips for $25 or $100 chips to simplify the chip stack. Chip up can also refer to the process of increasing one’s chip stack during a tournament or cash game.
