Let me give the AJ one a shot. I've never really used ranges before so this is very interesting to me. Keep in mind that I'm just a noob trying to act like the big kids.

Pre-flop:
So at these stakes I think these players could have anything pre-flop. Small suited connectors, small pairs, even a tight passive player with AA wouldn't surprise me. The most likely hands though are middle ground: JT, QJ, KQ, KJ, T9s, 98s etc., and maybe 22-99, more likely on the smaller side.

Flop
I think at this point he's not likely to be calling you with little pairs or suited connectors after a hodgepodge rainbow. He called with a player to act so I think most likely hands are still JT, QJ, KJ but he could have something like 9Ts and is looking to catch a card. Another possibility is 88, 33, or even just 78s. Maybe because he's a short stack he really likes second pair.

Turn
With the Queen on the turn I would now definitely fear the QJ and 9Ts, and I think I would check to him to see what he does and try and figure him that way. If he went all in on me then I'd give him credit for it. I lost the advantage on a lot of what I had put in his range. If he checks behind me then he probably does have something like 78s and maybe I'm still in control of the hand. As it was played I would think I'm beat as soon as he raises, but who cares what he has because you have to drop in the extra 0.32.

River
Doesn't matter.

Alright, I gave it a shot. Anyone want to grade me?
