I'm assuming neither, but I just wanted to be sure. Obviously I realize that it increases your variance. [/ QUOTE ] Reduces your variance.

I was trying it today betting $1 on 5 hands at a time and went on upswings and downswings of $50. I never get anywhere close to that betting $1 at a time.

Re: Does playing multiple hands in BJ hurt or help your EV?
How could it possibly change your EV? You're playing the same game, just more hands in a given amount of time. It changes your hourly rate, but not EV.

[/ QUOTE ] I didn't think there was a way, but I've been known to overlook details. Perhaps matching 5 hands up against 1 is somehow different than 1 against 1, I speculated. Anyway, question answered. Thanks.

Bet 1 hand of $1 vs. 5 hands of $1, variance goes up. Bet 5 hands of $1 vs. 1 hand of $5, variance goes down.

Re: Does playing multiple hands in BJ hurt or help your EV?
The variance of 3 hands (saw you said 5, i know) is 1.5x the amount of the total of 3 hands bet one 1 hand.
three x $1 vs one $3 hand. EV is EV regardless of how many hands you play at a time. The house edge doesn't change, therefore the EV doesn't change either.

Re: Does playing multiple hands in BJ hurt or help your EV?
assuming you aren't playing online, more hands means more cards you can see. if you count cards...

It depends
[ QUOTE ]
Does playing multiple hands in BJ hurt or help your EV? [/ QUOTE ] Ordinary gambler You wanna be earning more comps so better concentrate your money in one spot and thus improve your "bet size" as measured up by the host. On the other hand, if you are already on your way into the favorite guests' book of the casino, you can spread your money into more boxes and thus delay the game further. (It is assumed that you do this anyway.) Basic strategist There is no such animal. Card counter When the count indicates that the remaining pack is good for the player, it is better, in general, to conserve cards rather than "spend" them. In other words, it is generally better to bet on one spot and, thus, get as many rounds as possible. (From the point of view of optimal betting, you can get a significantly "safer" game, as well as a more productive one, by spreading to 2 hands when heads-up, with 75% of your original bet wagered on each of the two boxes. See the link about Kelly, below, for more on this.) This notion, however, runs into trouble when there are many other players at the table eating away at your good cards! In such a case, it is genrally better to bet as many boxes as possible. (Side note: In some casinos, it is possible to bet behind other players. When you can be the rider in a good count, be so, since that box is gonna be open in any case --- but make sure the player who commands the box will play the hand properly or is willing to listen to advice.) Schlesinger's Blackjack Attack has it as follows: 6-deck game, DOA, DAS, S17, 75% pen <font color="blue"> With how many other players at the table / How many hands you should be playing: 0 / 1 1 / 2 3 / 3 4 / 3 </font> When you know the next round is gonna be the last one, spread to an extra hand, in all cases. Some well-bankrolled players will spread, in such a case, to the max number of hands. The opposite tactic is also valid: When the count goes south and, for whatever reason, a break from the game is not possible, then you keep playing at the minimum bet size. And, all things considered, it is better at this point, in general, to eat away the bad cards by opening up multiple boxes.
