[#] 11 [Rule] A single oversized chip will be considered a call if the player does not announce a raise. If a player puts an oversized chip into the pot and states raise but does not state the amount, the raise will be the maximum allowable up to the size of that chip. After the flop, an initial bet of a single oversized chip without comment will constitute the size of the bet. To make a raise with a single oversized chip a verbal declaration must be made before the chip hits the table surface. [Rule Title]
