I found some player never double or spilt any card , they afraid of losing one more bet , actually what will be the house edge of playing in this way, since I think this will make blackjack the most negative game in the casino , may be 6% loss to the dealer
Actually its about 3.1% IF you are paid 3:2 for BlackJack.
Surrender lowers it to about 3%.
This also includes NOT hitting 15 or 16, and its different than Ray's answer. Hey, if you're not gonna split or double, might as well stand on 15 & 16 too.
but i play the blackjack game for thosands round , i found players winning rate is around 44% only ,so if just add the little advantage for blackjack and surredner , i think it should still be near 5% disadvantage
Proper DD reduces the HA by 1.5% and proper splits gets another .5%. That means there is 2% reduction that you want get. How this lack of reduction affects the HA depends on your local rules. All this is based on the fact that going 1st puts you at an 8% disadvantage. If there were no player favorable rules, such as: DD(1.5%), splits(.5%), 3:2BJ(2.25%), H/S(3.25%)=7.5% you would have no chance at all. So, 8% minus 7.5%=.5 HA
It is easy to see why basic strategy players who do not make mistakes have a better chance to win................
Just a guess here,perhaps someone can provide the math,but I'm thinking if a player were to always stand on his first two cards and never hit,they still woud have a better advantage than some house games. Sic Bo has bets with a house edge of almost 20%,the Big Six is not far behind. I think some of the wierd craps bets-any craps,c/e,fieldbets and the rest are pretty bad,as well.Horse bets suffer an 18% takeout,or some such number.
Not necessarily. In a shoe game, a TC of +1 (hi-lo) means the game is right at break-even, although you might actually have a very slight advantage if the game is about -.5% off the top. So at a TC of +7, you have a roughly 3% advantage over the house. If you are playing a BJ game with rules bad enough to give a -2.5% house edge, a TC of +7 makes that a winning game for you, if you can "wong in" at +7 and higher, and "wong out" at +6 and lower.
So there are ways to beat bad games, in some cases. It requires a good bit of thought and analysis, otherwise you can miss a significant advantage play at times.
BTW US Roulette is -5.26 since we have 0/00 wheels for the most part. Never play the game myself, except once about 5 years ago when a friend found a slightly biased wheel. Still didn't win anything however, but did break even which is not that common.
Every roulette wheel is biased, just like every coin is biased (heads or tails). The problem is the degree and the mountain of stats needed to define what is likely an unuseable imbalance.
In Sic Bo,the best bets(hi-lo) pay even money but are a 15/36 probability. the worst bets(a particular triple)pay 180 -1 in Ac,150 in Vegas but are 1 in 215 chances. House edge is much worse than roulette,any bet you make.
Overhauls replace the small felt "pads" (with the numbers on them) with pads that are not as soft, or softer than the others, which slightly biases those numbers).
the "canoes" (the little gadgets that make the ball bounce as it comes off the ball track onto the wheel) can be loser on one section, causing less bouncing there.
This doesn't mean one particular number comes up all the time, but it does mean that one particular section of the wheel might get statistically significant extra hits that can be exploited. Remember that the wheel doesn't quite pay fair odds, with the 0/00 house edge, but the edge is pretty small. If you know that there will be an extra ball in one quadrant of the wheel every now and then, that can more than offset the house edge and turn this into an advantage situation.
"wheel clockers" watch a wheel for hours, recording every number, and then analyzes to look for a bias. If you plot the numbers hit on graph paper, you are looking for a "normal curve peak" somewhere in the numbers showing that several numbers are getting a more than average hit rate. If you re-run the test the next day (being sure the wheel has not been moved to another table or rotated in the existing table) and get similar results, you probably have an exploitable bias...
There are books written on this, although I don't play roulette myself.
Being that this is a Blackjack forum, I hope the moderators don't mind one more question on roulette:
I read where a roulette "dealer", after several years of working, actually formed a habit of spinning the ball the same speed, with the same motion. And this pattern could help an experienced player predict where the ball lands. Do you agree this could be another "bias"?
There are supposedly dealers that can "hit a target quadrant" on a wheel, by spinning the wheel at the same speed, and then doing the same with the ball. They can get into hot water, because they are supposed to never take their eyes off the layout while spinning the ball, but to "hit a quadrant" they have to index the wheel to some point (say when 00 passes some specific point, scratch, design, etc). That requires them to look carefully at the wheel when spinning the ball, yet they are told to keep their eyes on the layout for chip protection reasons. If you see a dealer watching the wheel when he spins the ball, I'd be extremely careful playing at that table...
I have heard of this on the "big 6 wheel" or whatever it is called, as if the wheel is spun at the same speed each time, one can get pretty close to predicting the final stopping point. Roulette bias would be tough based only on a dealer, since the "bias" would be eliminated due to the random wheel position when the ball is released, even if the speeds are identical each time. But if the dealer watches the wheel, it could certainly happen.
