Match the Stack
Match the stack is a room rule that allows a player in a cash game to add chips to equal the largest stack at the table. It lets players keep up with a big stack that has grown during the game.
The simple explanation
Normally there is a maximum buy-in, such as $500. If someone wins a lot and has $1,000, the 'match the stack' rule lets others add chips up to $1,000. This keeps the game fair and often leads to larger pots.
A closer look
The rule is common in live games and can make the game deeper as the night goes on. Players with deeper stacks have more room for tricky play, and the game can become more skillful. If you see a game with the option, check how and when you can add chips, because rooms have different rules, such as adding only between hands. Playing with a bigger stack than you can afford is a risk, so use it only if you are comfortable.
A practical example
The buy-in cap is $500. Two players with $500 go all in, and the winner has $1,000. Any other player can now top up to $1,000 under the match-the-stack rule.
