This is low level stuff. I'm still learning (obviously) so I've only been playing the $5 and $1 tourneys when I get a chance. This play was typical of him recently. He'd limp and wait until people got in and then he'd raise or reraise the first chance he got. It is in fact how he knocked out the guy in 7th place. That time I believe he got lucky on the turn to get the card he needed.
