Possible Cheating (Long-ish) Please Help

We had the exact same problem in my home game. I talked to the guy by himself. He admitted it right off the bat and felt horrible. He was going through some tough financial times and needed a quick buck. I felt for him but was still pissed. So, we let him stay in the game and just kept an eye on him. Hasn't been a problem since. We also changed our shuffling/cutting procedures.

My suggestion is to have another shuffle underneath the table and, kind of jokingly say something like "man, lots of people dealing in weird ways, we should set something so we're all doing it the same way."

That way, he's not accused, but you solve the problem.

Just my 2 cents.
