Now that I think about it, you did say you were on a cruise.
It's just that I'd never seen anyone using 1-2-4 before (until the guy sitting next to me at the Gulfport Grand Sunday night); so it was your betting method which jumped out at me to the point I forgot the other details.
I finally left there for a 2-deck pitch game elsewhere (absolutely NO heat -- surprising -- especially since I was able to get the bet up to ten times my base bet a couple of times on good counts), and made a little money.
No, don't ask where. I don't want to poison the well.
