Seems like over the years the way they've dealt with card counters is by tweaking the game, though. They've added decks, they shuffle sooner, they shuffle when you increase your bet or when a new player sits down and plays for nontrivial amounts, and lately with continuous shuffling machines.
1. Field has 2 or 12 pay triple and the other pays double
2. 5x odds bets or better allowed.
3. Minimal / no restrictions on place bets. ( some table don't let you do place bets on 6 or 8 )
And then follow these rules:
1. Only do field, place, or come bets
2. Always have your place and odds bet "working" - you will have to tell the dealer
3. If a number is rolled that you have an existing place bet on convert it to a odds bet.
4. Limit the total amount of money on the table - one 7 will wipe everything.
5. If you feel nervous, take all the money off the table that you can. Let the last few remaining bets play out and then walk away.
6. Lastly, and most importantly limit yourself to a specific amount of time or rolls. This is especially important if you are winning.
> Only do field, place, or come bets
The house edge on the field with those rules is 2.78%, which isn't bad, but isn't great. Ideally you want one that pays triple on both 2 and 12 (good luck finding that!) because then the house edge is 0.00%
All the rest of your bets are either 0% or 1.4-1.6% house edge.
Also, if you're really worried about one seven wiping you off the table and don't mind being contrarian, play the don't. While the odds are basically the same (slightly better actually) in the long term, I find the short term odds much better (because of the aforementioned deadly seven).
However if you value the social aspect of the game or your casino player rating, don't play the don't. :)
Also impossible for the casino to make a subtle rule or behavior change that negatively affects the odds.
I personally don't know why casinos bother worrying about card counting. All they really have to do is increase the number of decks and/or increase the reshuffle frequency.
Or if they really want to stop it but some house rules that say that the next bet can't be any more than 2x the previous bet.
Sure they might miss that person that is going to go all in on one last draw. But whatever. Besides gambling revenues are down and non-casino revenues (like shows) are up. So maybe Las Vegas will stop being a gambling mecca and just be an entertainment hub.
I got so angry when I see a blackjack table with a 6 for 5 payout on a blackjack and the lack of surrender.
If you count cards on a small hand shuffled shoe, even with a basic system it is relatively easy for a player to have a fraction of a percent edge. Good players can have a few percent edges.
However, most casinos nowadays use large shoes and frequently (or even constantly) machine shuffle the cards. This effectively almost completely negate card counting.
It's perceived the smaller shoes are better since they are easier to county, but with a smaller shoes the count can't swing as far one way or another, so with a large shoes there is a high probability of getting better odds.
The main thing they do is not play through the whole shoe, i.e. they shuffle before they get all the way through. This prevents the count from being allowed to swing as far as possible.
I think the guy who explained it to me was talking about a combination of counting, pattern recognition and other such strategies, hence my confusion.
