Hold-em or Omaha?

Yesterday I left work with the intension of picking the boys up and taking them to the park or the driving range but unfortunately it was raining quite heavily so with the consent of their mother we postponed it until wednesday. I had intended to go up driving range myself after and then go for a run aswell but had to have a bit of a rethink because of the weather. I decided to have a quick game of poker on the internet which I haven`t done for a while. I found a tournament that was starting soon and with an entry fee of only $10. Unfortunately I had mistakenly entered a pot limit omaha tournament (I usually play texas hold-em), I have watched omaha being played on the television before and it`s similar to hold-em (in omaha you start with four hole cards instead of two) but I wasn`t sure which starting hands to play and which to fold and at one point a friend of mine called me on the phone and I totally misread my hand. I think I ended up finishing 17th out of 36 players which is reasonable for a first attempt. I may have another game at some point this week.
The rain subsided after a couple of hours and I went up the driving range after all. I was swinging really well. I then went to Hayes ceroc and had a pretty good night.
