.... Just doesn't seem to be enough benefit to justify changing the overchip rule for the last remaining chip.
How about an enhancement?
45: Oversized Chip Betting
When facing a bet or blind, pushing out a single oversized chip is a call if raise isn’t first declared, even when it's your last chip.
Where do you see, "even when it's your last chip."?
I'm reading it right now, and I can't find it. In fact, I did control find and type that in and nothing came up. Here's the copy and paste for rule 45 from my side.
45: Oversized Chip Betting
When facing a bet or blind, pushing out a single oversized chip is a call if raise isn’t first declared. To raise with an oversized chip, raise must be declared before the chip hits the table surface. If raise is declared but no amount, the raise is the maximum allowable for the chip. When not facing a bet, pushing out an oversized chip without declaration is a bet of the maximum for the chip.
Nothing about the last chip.
