Not a very hard game to pick your opponents at. You only have two cards. Playing your two with the 5 community cards. Each flip of a card is the time to read your opponents. Chances are, they are not pro gamblers. Most of the time there will be an easy tell. A slight grin. A blink. An intense study of their hand. All are signs. You just have to decipher if they are happy or upset about the play. I would think y'all keep it simple. No small or large blinds?
