I had a situation where the dealer accidentally revealed his card (an ace) thinking a player wanted to hit when he actually wanted to stand. The dealer had a 6 showing and after some initial hesitation, I convinced everyone with subtle or maybe not so subtle hints not to take a hit because it wasn't going to improve their hand since all of them had stiff hands. I knew that I had just been given a GOLDEN opportunity. I had a made hand that could be improved with an ace 
At the same time I was getting a lot of heat as there was one pit critter standing outside the pit where people usually walk through, standing there, inspecting my play. I was debating whether to double down there where I would have a huge advantage or just stand pat to avoid getting even further increased attention. Since the count was semi good and I had raised my bet, I guess the greed took over and I doubled! I was afraid the dealer was going to yell out doubling hard 18 but thankfully he didn't. Needless to say I won a nice unexpected chunk of money on that hand but I figured I had better cool it so I left the table as soona s the count went back down. Do you think I did the right thing or should I have not of even of doubled?
