Firstly you said you were trying to get a read off him by talking, I take it that didn't work so you tried exposing your cards deliberately to get a different read? Unless there are only 2 people left in the tourny this is a big no no in my book (not to say different TDs and places have different rules, so I am just commenting on what i would do)
There were only 2 people left in the hand. I can't see how it matters how many are left in the tournie as long as we are heads up in the hand and the only action is on me to call or fold.
I was trying to determine whether he had just hit 2 pair or was making a move/semi-bluff and if I have the ability to figure out how confident an average player is by talking to them then i don't see why I cant unless it's down as black and white as forbidden by the house.
"No table talk" etc. is so last decade ! I dont really care if others at the table think i'm being unsportsmanlike as long as i'm not breaking any rules.
I've only ever had people get upset with my antics like this when playing in places like london, vegas everyone is doing it.
It was BBII and the main element was fun. What i did is what makes poker fun and interesting for me but I may have showed a bit more class and respect if the stakes were higher.
