Did I do the right thing?

[Blue Efficacy]

First hand of shoe. Ploppy at first base notices the dealer didn't burn a card. I got A,9 dealer showed A. PC asks if i want to pull bet back, she asks me if I am sure a couple times.. Dealer did not yet check for BJ.

Did I do the right thing by playing the hand?

BTW the dealer also had soft 20.

You did 'good'

With 19 or 20 you are a favorite to win against any dealer's "up card".

Oh %&$#, the EV tables at bjmath are gone.

Anyway, the EV for A,9 vs. A is about +.60, so yes, it was correct to play.

EDIT:

Not so fast there, Canceler! The +.60 assumes the dealer does not have BJ. I expect it would be still +EV before the dealer checks, but I don't know by how much. The question becomes more interesting now.

That's pretty easy to calculate 4/13 of the time will result in a loss versus 9/13 of the time will result in a +.60 advantage

= 4/13*(-1) +.6*9/13= .11

So yes there is a significant advantage

Ideally, of course, get the dealer to somehow check for BJ before making your decision.

Right move Just what I would expect from you.

Thanks for the compliment, I figured a true BJ warrior wouldn't throw a 20 into the muck so easily. I was playing a mighty fine 6 deck game, and if you're not going to let a 20 play, why even bother I thought.

You did the right thing, now let us expand this kind of situation

Had an instance near the end of a shoe (high count) where a new dealer came in, did not burn a card (house procedure), got an ace while I had 20 and the pit gave me the same choice.

I tell the pit that I will play if the dealer does not have blackjack and at first the pit disagrees. I then go into the whole Sacred Flow senerio, combined with the cards obviously being out of order, and furthermore only being out of order because the casino made a mistake, so why punish me for the casino's mistake.
The pit bought it but the dealer had a blackjack, so everyone bowed out of the hand.

This was a max bet situation where I would have bought insurance anyway, so I figure I got my insurance for free. Not so sure I would have made myself that visable to the pit if it had been a minimum bet situation.

I'm afraid I did make myself visible to the pit in that minimum bet scenario. The PC seemed to think I was quite stupid for staying in against the mighty Ace, even with 20.

With 20 always play out the hand! Especially in that situation where there was an error on the hand and the pit boss might instruct the dealer to push you if he does beat you which happens 25% of the time in a weird situation like that. Even if it doesn't happen the dealer has only a 30% chance of having a blackjack so you are huge favorite anyway.

Rest easy.

Either he's the quite stupid one or he's quite the smart one trying to get you to make the wrong play lol.

Ask him for a private table where dealer has Ace up and you have A,9 on the first hand and just play out the shoes keeping those cards since you're so stupid. Bet more than the minimum too lol.

 

[Kasi]

If you are ever in Blue's situation and are dealt a 10,9 vs dealer Ace and are given the opportunity to remove your bet before the dealer checks for BJ, thank the PB for your get-out-of-jail-free card and take your bet back.

Chances are it's -EV before he checks for BJ but +EV after he has checked.

Actually it was a "she" pit critter.

Didn't seem very smart either.

But 1/13 of the time will be a push. 2/13 of the time will be automatic win (H17). 6/13 of the time the dealer has a chance to outdraw me.
