My remarks:

1. With a hand like that where you're mostly going for TP-action, you need 1-2 to see the flop with you. More people means you have on average less of a chance to win. Your preflop raise is good, just wanna say that if a raise like that on this table frequently gets 3+ callers, raise more til it gets you 1-2.

2. Flop bet is a mistake. Patience my friend. You have nothing, so why throw money in the pot? If you want to bluff them out, you have to throw more. A bluff would probably not be the best idea here ofcourse, since there's 3 people and one of em is a confirmed calling station. But in this kind of situation, either throw 2/3-3/4 pot for a c-bet (bad idea here) or Check (what you should have done)

3. River.. why call this? All you have is high card Ace. If he has *anything*, a K, a 2, a 5, a small pp, you're out.

4. Don't even be fooled if you did happen to win with high card ace here, or in a similar situation. You'll blow WAY more money on stuff like this in the long run, even if you're up against a loose aggressive idiot. You just needlessly threw away $7 here.. so if you do this one more time, and then cash in $14 on a good hand and a good flop, you just broke even. If you had saved your money for those times that you had something to go on, then you'd be up $14.
