I'd say the Cards are glad to get back to action and out of practice. I'd guess rebounding was worked on alot after Tuesday night meltdown on glass in the fourth quarter.
A few variations of tonk I have seen over the years. Some play that if someone plays on a spread that holds them from going down for a round. Some play if you get 49 or 50 on the deal is automatic winner and some places pay 50 double. Different games pay differently if you go down and lose also.
I used to play some in college but not much anymore. A few of the old guys play while waiting for our cash games to start. Many variations of that game plus there are many ways to cheat, etc. So be careful. Haha
