I was sooooo stunned after this that I have to post these hands and get some feedback. Did I really play this that badly? I have put in my thoughts as I went along so you can know what I was thinking.

Hand 1 - He is so short stacked that he is probably pushing ATC. My hand is a slight underdog against a random hand. I almost folded this and probably could have waited for a better spot as I didn't have much fold equity against him with just a raise. Not sure if he would have folded to a push but that would have been better than a raise here I think.

Hand 5 - You can't just raise with good cards so I thought this hand was good enough to try and steal his blind with, but I don't like calling the push with a kicker as low as a 4. I don't think his range here is that loose so I think I am most likely behind here. Too tight?
