card counting?

[free4all]

can you actually beat the landbased casinos with counting cards? or is that just a myth? or do they shuffel to offen for the counting to work?

Im not asking for any method or anything, just wondered if people still do it.

A group of students from the Massachusetts Institute of Technology took Vegas casinos for millions by card counting a few years ago, so it is possible but not recommended unless you want to be persona non grata at every land casino in the country.

They've done things like implement continuous shuffle machines to replace the shoes and cut the shoes deeply (penetration) to make it harder for counters. Many people seem to think it's illegal, which it is not, but it's not welcomed.

Counters don't count the cards remaining in the shoe.
They memorize face values so they know what cards have already been played on the table. Best way to stop a counter is to shuffle the deck every hand.

It's still done.
It's getting harder.
It requires a lot of memorization.
It's boring as hell.
It requires a huge bankroll.

That wasn't what I was saying. The way I understand it the more cards played from the decks the better it is for the counters.

Same group also suffered their share of losses, not to mention several reincarnations.

You can create a positive expectation game - meaning that you may still be unlucky and lose, but at least the percentages are on your side.

Most people think that card-counting simply involves figuring out the number of ten-valued cards and aces remaining in the shoe, then altering the wager accordingly. It also involves altering basic strategy; most effective card counters also use a half-deck divisor to better approximate shoes with low penetration.

Varying your bets is more important than varying your strategy, although single deck can be beaten by strategy variations. Here are the average hourly loss/win figures from Professional Blackjack by Stanford Wong (1994, p. 50). (I am not quite sure how many decks, it could be 4 or 6).

Flat bet, basic strategy: -$15/hr
Flat bet, vary strategy with count: -$14/hr
Vary bet with count, basic strategy: +$12/hr

It is clear that bet variation is much more important.

There is another factor, you can also take insurance bets with positive expectation when you are counting.

Of course one must vary the bet when you card-count, but the most effective strategy involves variations in both wager size and basic strategy. For example, although most would normally double on an 11, a shoe with a very high negative count (meaning fewer tens left) might dictate a hit rather than a double on an 11.

Most casinos, btw, also have strategems to prevent players from effectively "Wonging" in - eg watching a table and counting as a spectator, then suddenly jumping into the middle of the shoe. Many double deck games, for example, do not allow mid-shoe entry, and the 4-6 deck shoes set a lower max bet for those players (eg a 200 max limit for someone Wonging in vs the table limit of 1000).
