Next card out of the shoe exposed

So I was playing 1st base and a hastey dealer pulled the next card out of the shoe and exposed it to me, then shoved it back. It was an ace. I sat out the prior hand to color up and cash out, after seeing the next card was an ace I put on my best poker face and declared "All In"! about $1875. Sound like the right play? Results to come later in the thread.

Not knowing you, or how much you gamble with, or how good you would feel with $3750 (or $4687.50) or how bad you would feel with zero, of course from a purely mathematical perspective you should bet it all. As per a few threads going on here, if you believe the dealer intentionally showed you the card then it can be inferred that you two were colluding. If you believe it was an accident, then, I would say it is up to you to decide what to do.... So... what happened?

Unless the count is way low, it is the right play from the EV standpoint. Whether you won or lost doesn't matter, what matters is if you made the right play. Learning from own experience may be natural, but it is only the right play when you don't have access to extensive data from others' experience and computer simulations.

A good gambler doesn't mourn or celebrate his losses and wins, he slaps himself when he made the wrong play, even if it wins, and pats himself when he made the right play, whether it ended in win or loss.

I wonder sometimes how come it's not considered cheating in poker to read someone's hand or get him to reveal it, but is in all other games.

actually the dealer should have burned the card. I know the casinos I been to if an extra card comes out of the deck when its not yet wanted they will burn it

I would have pulled the bet back in that case. The dealer was actually trying to get a tell on me if I saw it or not. That is where the poker face came in.

Kelly criterion says to bet about $1000 in that situation. The EV is ~55%.
