Many people have beliefs and preferences for certain cards. There are people who say that when they get AA they only lose. And others with low pairs always take the pot.
Do you have a hand that you always play when you're with them?
I don't have a Favourite hand, as they can all lose, I stick to playing position on a table and after I identify the Weaker players I will play against them, but I am always aware that "Every Dog has his day" and even the greatest underdog in a hand can Win.
Once in a Live game I was on the BB and dealt K/10 off, Which is playable but not I would call a great hand, The player UTG shoved all-in after announcing he had his Favourite hand, and at first I thought I might have to fold but as everyone else at the table folded around to me. He made a fatal error in adding that his Favourite hand was Jack/10. Now it doesn't take a Genius to know that I had him beat Pre-flop and all I would have to be scared of is him hitting a Jack or Straight, so I snap called. Neither of us hit a single card on the Flop, Turn or River and my King high took him out of the game.
I told him afterwards that I actually considered folding before he told me what his cards were and having no reason to suspect he was lying I called simply because I had the better Kicker if we both paired the Ten.
So no, I don't have a Favourite hand, because even the Favourites lose!
