If I'm playing with someone trying to be really "cool", shades, music buds in the ears, hoodie.....and they seem really active, opening a lot of pots, making big squeeze bets, lot of postion play, ect.....I sometimes tell them that I can see the reflection of the cards in thier glass'. Actually, I have only done this a twice that I can remember, both times I had ulterior motives to my claim.
I told them, w/ the most honest, concerned & sincere voice and tone I could do...."dude, I can see the reflection of the cards in your glass', just thought I'd mention it to you as a courtesy".
Both times I said this to players my true motive was that I wanted them to stop being so aggressive because I was outta postion and wanted to play more hands, and I wanted to them to *think* that I could, or maybe could see the relfection, but in any case - more than anything I wanted to them to be slightly distracted and choose thier hands more selectively and quit stealing so much...so it would give me more of an opportunity to steal some more....and both times I did this it worked
