I apologize, Robbie. I didn't phrase that correctly. The one pit guy has a list of 5 things that counters do frequently that he uses to ID them. Only 3 are about how they play a hand. They are all obvious, common sense, type things. Bet spread, spreading to 2 hands, and how they play 16 vs 10, insurance and splitting 10's. He stated that individually none of these mean too much, but he is particularly interested when he notices a player do 2 or more of these things.
I just found it interesting that at the top of this guys list was the play 16 vs 10, while the second guy I spoke with 16 vs 10 was the only play he looked for. The play itself is fairly insignificant, as we know, except at higher counts. But I guess because the hand is very common, the single most common hand, if I remember correctly and because the index number for playing the hand differently is right at zero, it is pretty easy to notice when players play it differently.
Now, I realize that the opinion of 2 different pit guys isn't worth a whole lot. It's a pretty damn small sample size. Unfortunately, I don't have access to hundreds of pit guys that I can poll and see what they are thinking. I have just 2 or 3 that I know well enough to pick their brains and discuss things like this with. But since the two that I have had this conversation with both mentioned that 16 vs 10 hand, I have incorporated it into my play, as it costs almost nothing, especially with my aggressive wong out style of play.
