Don't look at the cards until you have to act, regardless of what the table is doing. Always stop and look left before and after viewing your cards, you'll be amazed by how much information is given up right there. Generally, people with hands on chips have hands, players that already protected their hand with a chip or card protector have hands and people that look like they are going to fold, usually are. Pay attention to which players at your table are looking at their cards as they are dealt.
