Just as you do when you cross the road look right and left and make sure you are aware of the action. I busted 15 minutes before the end of day one because I’d failed to notice a mid position limp and thought I was blind on blind with a simple 8 BB shove with K8. The big blind folded but the limper called with his pocket eights and I was out. If I’d seen the limper I would have folded and found a better spot to get my chips in.
Look left and right – Before you act make sure it is safe or you could get run over.
