RANDOM VERSUS RANDOM--WINNING WAYS

[kampfgolem]

Hi, I started lurking the forums a couple months ago and just stumbled onto this thread. I still don't get how the betting is done. Is it done like this?:

24B
6B     - do I start betting here? If so, is it R 1 [opposite], B 2 [last + penultimate]?
34R   - R won, so: R 0, B3?   Or do I have to bet on R again? (R 1, B3)

Thanks a lot
