This hand is scary in many ways and in other ways it's just funny. At first I was in disbelief and then I just started laughing.

I was playing 7 tables at the time, had been for about an hour, and my brain was fading. I was actually looking at a hand I had on a different table and playing it on this table. Wow, lol. At least I didn't have QQ on the other table, that would have been a lot more expensive.

This leads me to wonder how often this happens where I don't notice. I caught a hand a couple weeks ago where I folded Queens preflop to a 3-bet after I had raised. All I knew that time was that I had been 3-bet after raising with Queens and when I looked back my Queens were gone - I ended up searching the HH window to figure out where they went.
