Pardon the ignorance, but I'm still a newb and trying to put actions to numbers here... So what does .4 AF tell you? What can you expect from this guy? Is this a sign of someone that only bets if they have the nuts? I'm trying hard to watch each players betting patterns, but nothing about this guy stood out, so... He's led out betting before (not often, but a couple times... couldn't tell you what his cards were off the top of my head though), but hadn't won any hands yet (out-kicked a few times, the usual).

thanks
