Should and have to be shown during all-ins only IMO.
Funny how you put Candians in a class of their own.
I guess Candians are a seperate ethnic group.
But still, why not get rid of the "show your cards" rule? Why have it?
It's there to prevent collusion.
If it weren't there Player X and his friend Player Y could make an agreement before the tournament that if they get seated at the same table, when they get the chance Player X is going to shove and Player Y is going to call regardless of their cards. Player X will show their hand and Player Y will muck, even if they have the best hand, because the deal was that Player X is the one that gets the chips. This gives Player X an unfair advantage in the tournament.
This was my entire point. In the scenario described by this thread, collusion could have been a possibility for what happened (although I personally doubt it was). By allowing Player A to muck his cards the tourney director could have (and may have) allowed collusion to take place amongst two of the biggest stacks in the tournament.
