AI, I was at Mt. Airy today and from what was explained to me, they mean a "partnership" as opposed to "team".
Last night at Mohegan Sun in Wilkes-Barre, player to my left had $50 bet and received two 8's versus dealer 5. Count was +3. He then split and and made 17 on first hand.
On the second 8, received another 8 but didn't have any more money to split. I told him I would take the split, which I did. He pulled to 17 on the second 8.
On my 8 I pulled a 2 and then doubled.
If he was betting more than half of table max, my double would have pushed my bet over table max in what they may view as a partnership. I may be wrong but I believe this is the situation they are addressing.
Then again, who knows what's going through their minds.
