I was playing on Full Tilt for a bit. I had just started playing cash seriously and started at the 10nl level with a bankroll of around $200. I made some bad plays my first session, but soon realized my mistakes. I was able to do alright at 10nl and had $300 in a couple of days. It was at this point that I learned of rakeback (Ive made some threads on here about it) and couldn't get it on my FTP account. I finally decided to switch over to PS because I could get the 100% bonus on $50 and I could get the 40% bonus on $240 reload bonus before the end of July. I deposited $50 and started to play 10nl again. Although my roll was only $50, I was going to be depositing the other $240 in a couple of days, and I wanted to get the bonus moving. After switching, I seem to play terrible. I dont know what it is. I think that in my attempt to be more aggressive, I end up just donking my buyin away with trash. I have been buying in with $5 as opposed to my usual $10 because of my bankroll as well, so that could play into it as well. But I am down to $15, and have until the end of July to deposit the $240 for the bonus. Should I just play 2nl for a bit to remember how to play? My only thing with that is that it doesnt get the $50 bonus moving, which I have to clear before I can work on the $240 bonus. Any advice is appreciated.

Also, I have a few questions as to what to do in certain situations that seem to come up:

1) The table has folded around to you in the SB and you hold Ax. Do you raise in hopes to steal, limp, or just fold because its not worth it? Or do you switch between these 3?
2) It is folded around to you in LP and you hold a small PP (22-88). Do you limp to hit a set, raise because you are the first to enter a pot, or just trash it? More likely to raise with 88 than 22?
3) There is a MP player who raises to 3x the BB. You are CO/Button with AQ. Do you flat it or 3bet it? Ive been under the assumption that it is normally bad to just flat a raise...although you would have position in this case.
