Here's a question that I saw elsewhere that caused some debate:
$10,000 O8 (Limit) tourney at the 2011 WSOP. Blinds are 1300/2500:
Limp, call, call, sb calls......
The big blind has a huge stack of all colors. He's got stacks of 100, 500, 1000, and 5000 chips. He posted his bb with 2 orange 1000 chips and a purple 500 chip. He has the option of checking or raising at this point. He reaches into the pot, grabs his 3 chips, removes them, and then replaces them with a single 5000 pink chip. He does this without a saying a word.
Some players at the table thought that he had raised. Others at the table assumed that the big blind's action was a call.
What is the correct ruling?
