In fact it is very easy to judge your opponent if you know some of the reactions that are obvious by the players while they play poker. A player with nuts will try to behave in an opposite manner or will seem a bit uneasy to you and will try to check his clay poker chips every now and then.
Usually a player that has a big hand will talk very less, look to his left and will be concerned in what others are doing, will make sure about his clay chips and will also try to pose to be taller than others and may be stretch a little or get up a bit from the table. These are all non-verbal communication or the language that is understood by gestures.
Besides this type of communication, tell is different and will let you know the real position. If the person has a good hand, his tell can be forehead wrinkling, making or not making eye contact, yawn, sigh, gasp, blush, breath faster, smoke, drink, play with the clay chips and so on.
