....I don't play it as fast as I used to (in NL) unless I'm the first raiser.....

In this particular case the person who raised was the 1st raiser and the caller--the small blind,--had absolutely no reason on earth to do so as he had about $2,500 left with the blinds being $100-$200 (or possibly $200-$400 as I am not sure.) In addition, the raiser was a solid player and although aggressive, not wild by any means.

Bottom line is the this wild player was eventually knocked out as he couldn't keep rivering the winning hand 100% of the time.
