Time for me to move back down...

I prematurely moved up to the .1/.25 limits because I made about 150 dollars at the .5/.10 table in less than 3 weeks and I thought I could handle it. But yesterday I lost about 30 dollars, my first money losing day of poker. I'm not properly bankrolled anyways (200 dollars) so I'm going to move back down I believe. This is my 4th post from yesterday's hands, have a look at it.

Seems like whenever I slow play, even with a rainbow flop, the worst possible card comes out, so I think i'm going to stop doing that.

I think it's usually a bad idea to call a raise with AJ unless it's suited ... and even then you could get into trouble. Ideally, you want to flop top 2 pair.

... Which you did. But then you bet too little on the flop. I would have bet at least $2 here. 2 pair is not something you want to slowplay, even top 2. (Sometimes I slowplay AK x 2 ... but it can really bite you in the ass.)

After that, the Q coming on the turn was just unfortunate for you.

After the raise on the turn, I think I would have check-called on the river.
