I had my max bet out this weekend and the dealer showed an ace but accidently flipped over her hole card and exposed her hand before I had a chance to make my play. The floor manager came over and instructed me to play out my hand with the knowledge of the hole card. The hole card was a 3. I was sitting with a hard 12 and wasn't sure what to do. I was using the hi-opt I count with a side count of aces and the count was +4 in the single deck. I forget what the ace count was, but I decided to stand on my hard 12 against the soft 14. The dealer ended up making a hand. If I had taken a hit I probably would have won the hand. Does anyone know how to figure out the correct play on this?
Also - does anyone have any suggestions on how to figure out how to play a hand when there is an exposed card and you don't have the right play memorized? I realize there are probably charts that you can refer to - but any suggestions when you are sitting there and having to make a decision within a couple of seconds.
