They say that the first step is to find a strategy that works with a book. I used my "Craps System Tester" which has over 300 hours of actual play. It's not a lot, but I would be winning 81 units. If those were $100 units that would be $8100!! Sure beats a kick in the pants.
Wait for a new shooter to roll a 7 on his/her first roll. Then bet (one time only) on the 12 for the next roll. Then wait for a new shooter to qualify by rolling a 7 on his/her first roll, and do the same.
There were a total of 725 bets made out of about 10,000 decisions (over 35,000 rolls). So I would be betting on only about 2% of the rolls (or 9% of the decisions). That means that I have to do something else in between just to hold my place and my interest. Also to keep the dealers from knowing what I am doing. My thought is to use the method of betting that the next prior decision will repeat. That means that the decision before the one that just ended will repeat. I would have to keep track of the decisions with dice in my rack (red for don't and white for pass, or something like that). My recollection is that I came out ahead on that with a partial run through my 300 hour book. I'll have to try it all the way through some time. If there are 2 different methods that work and they are used together that would be very good. I could play that with $25 units (or, even $100 units if it works). They would then think that the bets on the 12 are just hunch bets.
I guess, in the beginning, at the real tables it has to be done all with $5 chips, so as not to have high risk.
