Some dealers do not wait for your hand signals on no brainer hands, for example twenty vs anything. Recently I had a dealer that would do this regularly, especially when I was sitting at third base. Naturally I began training her to do this, giving no hand signal on very obvious cases but immediately signalling for anything close such as 12 or 13 vs 6, thus reinforcing her tendancy to do this.
So obviously this is a very easy error to exploit, but I will probably only be able to pull the hammer once, so I figure it is best to wait until you have 20-30 units or more out there. What exactly should I wait for? A big bet out when the dealer has a hidden sixteen (then doubling or splitting to exploit this fact?). Knowledge of the next card? At this joint they do not burn exposed cards, they are in play as the next card. Should I wait for an ace to be drawn and then double down and receive it on my 20? Or should I try and save a tough loss, for example I stand on 12 and 15 vs a bust card, dealer pulls the unlucky 6 or 7 to make 20 or 21, and then I demand to be able to hit or double my 12 instead of standing? Or should I just take the first clear cut case of +EV change when I have big bets out?
