I don't get the opportunity to make this play very often and one of the good ploppies said they'd never seen it done. I won't split 10's on a single deck because that obviously draws too much attention but this was pretty close to garnering the same attention. Single deck, 5 players, 2nd round, monster count, dealer has a 5 and I get the ace 9, so I double, and I'm 3rd baseman. You could hear a pin drop. Fortunately, we both got 10's so then I was instantly Einstein. Had it cost the table though, I believe the guns would have come out! There was so much chatter afterwards that the dealer felt compelled to yell player doubled on 20 while I said I only had 10. Yikes!
