I mis-read my cards! ANGER!

[PhatPots]

I am posting my hand here simply because misreading my hand cost me here. I guess it happens to everyone, probably more often in the casino than online. Usually because I try and lift my hole cards so now one else can see them. Please share similar stories. I thought my A [img]/images/graemlins/heart.gif[/img] was an A [img]/images/graemlins/spade.gif[/img]

I am sitting at 10/20 at casinorama. UTG+1 is a LAG (raises QTs UTg, he checkraises the river on a bluff, etc.), he is an older man who's English isn't very good. Most people sit at 10/20 with $400 this old man has a small stack but in it is a $1000 chip and a $5000 chip. MP3 is a younger guy who is getting really angry with UTG+1, Mp3 is a big talker and is saying that I shouldn't try to figure him out because I will just end up crazy, BB is a tighter player, UTG is kind of fishy

I thought I need 1 [img]/images/graemlins/spade.gif[/img] to give me the nut flush.

I thought that UTG+1 was probably holding Kx and that my K was good. When I had to turn my hand over I was shocked to realize that I had no spades. A few players said they thought I was on a flush draw. I felt stupid, anyone have any similar experience. Thank god that another spade didn't fall or it would have gotten ugly. Fortunately UTG+1 had no spades either, I thought my AK was good on the end, so I raised. I know some ppl would say that I should just check call there. The moral of the story, make sure you know what you are holding.
Comments welcome
