How about your ability to find many DD games with generous rules and 70% pen, so that after you've played at the first game for 15 minutes you're able to go to another game before getting backed off?
*You think they would back off a better going 1-4 units? Wow. I've never seen it . . .
I'm sure in your world it will be easy to switch from one hand to two or three in positive counts as well.
*I do it as past of a parlay or as if i am steaming . . .
You keep posting about playing in ways that I can't imagine would be tolerated for more than a few minutes in any one location.
*I think u and others are being overly conservative. I've played this way for years, ussually with a female partner, both of us a very extraverted and friendly, tip heavy, appear to play on impulse, play FAST, cuss a bit when u lose, do a little jig when I win big, pocket chips alot, on and on . . .
So your expectation may be $1k/hr., but I doubt that you'd be able to get in more than an hour's worth of play in an 8 or 10 hour day.
*Never played at $500 level, but at 4-1 with above mentioned techniques, we will see . . .
If that works for you, all the best.
