How do bots play?

Poker bloggers are always talking about bots in the cash games. I just play tournaments, so don't really know what they are talking about. Last night, I was waiting for a tournament to start, so jumped in the penny NL hold 'em game while I was waiting. I bought in for $10 and had worked it up to ~$15 when this hand played out.

I was in middle position and was dealt ♥K ♣K. After three folds, I bet $1 and it folded around to the BB who called. The flop was ♣Q ♠10 ♦9. The villain checked and I bet $1 into about a $2 pot. The villain called.

The turn was the ♥4. The villain checked and I did too. While there are no overcards, the Q-10-9 is highly coordinated and I had no clue what he had -- let's keep the pot small. The river was the ♠J giving me a king-high straight. The villain checked again and I fired a $2 bet -- I have a winner unless he has big slick, certainly a possible hand for how he bet. The villain called. In the showdown, my hand won, and he mucked.

I couldn't resist. I clicked on the hand history button and was totally surprised to see that he had ♥A ♦A. What a strange line of play.

Do bots play like this? Are they passive, or was this some kid out in Nebraska sitting in his dorm room, surfing for porn and waiting to check-raise me on the turn?

No wonder I don't play cash games very often (at least not online). I have no clue what is going on.
