Blown Opportunity

Played fairly well last night in a large tournament.  Was up as high as 3rd with 800 people left.  It started with well over 5000 people. 

I managed to blow my entire stack on 2 stupid plays though.  Funny, I was able to withstand bad beats and suck outs, but wasn't able to overcome my stupidity. 

I had great concentration all night during the tournament and let it lapse for only a couple of minutes.  Lesson learned I guess.
