I am running some tests on Oscar's Grind.

It's a pretty simple MM scheme which I believe is around 50 years old. All you do is start off at 1 unit. If you lose, you continue at 1 unit. On a win, you raise the bet by 1 unit and continue raising 1 unit on a win until you reach a 1 unit profit. You reset to a new game once you reached a 1 unit profit for that particular game. For an example, if you get to the stage where your bet is 4 units and you win and you then only need 2 units to go into a 1 unit profit, reduce the next bet from 5 to 2. Simple really.

Anyway, I don't want to test it for a million spins to see it fail. Instead, I want to see how often it can reach +50 without going to -20 just using a random bet selection. (black in this case)

If your bet selection is getting hammered by a 2/1 ratio.....It sucks! 

Oscar Grind is a proven failure way to play. Do not waste your time.

You are right.  Much risk, and no advantage over flat betting.

I tried Oscar?s Grind on these shoes, from bead plate photos posted by Al Relax.  Used a 25 unit loss limit.

"Mixed" is the bet selection I flat bet with. I tried it here using OG.

Betting P only, ended +13 units.  Max bet 5 units. Lowest BR was -6 units
Betting B only, ended -22 units.  Max bet 4 units. Lowest BR was - 25 units.
Mixed, ended +14 . Max bet 6 units. Low BR was -4.

Betting only P, ended +18 units. Max bet was 2 units.  Lowest BR was -1 unit.
Betting only B, ended -25 units.  Max bet 23 units.  Lowest BR was -25 units.
Mixed ended +17. Max bet 11 units.  Lowest BR was -22 units.

Betting only B, ended +9 units. Max bet 5 units.  Lowest BR was -7 units.
Mixed ended +13 units. Max bet 4 units.  lowest BR was -3 units.

Totals after five shoes:

Ended +18 units betting P only, with a 25 unit loss limit.  If no loss limit, would have lost 30 units.  If flat bet P only would be +11.

Ended -30 units betting B only with a 25 unit loss limit. If no loss limit, would have lost 80 units.  If flat bet B, would be -11 units.

Ended+15 units betting Mixed, with a 25 unit loss limit. If no loss limit, would have been +1 unit.  If flat bet Mixed, would be +19 units.

From what I heard from some Vegas old timers was that Oscar was a real person named Oscar and used the method playing Pass or Don't Pass at craps in the early 1970's or thereabouts.

Supposedly he did fairly well with the method....maybe he changed some of the rules to limit his losses.........but no one knows for sure.

Oscar was first mentioned in a book written in the mid sixties, that I have.  The book described his system and said he provided a hand written log of his sessions that showed he never lost a session.

His starting bet was $1.  It is possible he never lost a session with it.

I did a run for OG on WinCraps using a real casino dice roll file of 55K rolls.  I bet the Don't Pass only, which wins at the same 49.3% rate as the Player in Baccarat.

Starting with a $5 unit on the DP and no odds, the run ended +15K, or 3,000 units after 55K rolls.  Highest bet was 460 units, or $2,300.

"Starting with a $5 unit on the DP and no odds, the run ended +15K, or 3,000 units after 55K rolls.  Highest bet was 460 units, or $2,300 "

That's the problem with a lot of these martingale/progression  etc etc etc etc systems......       .you eventually are faced with a really bad run of losing bets and you have to bet $ 2000 or $ 2300 etc etc to win $5 or $ 10..........which is still basically a 50-50 coin flip to bet $ 2300 in order to win $ 5
