A toaster's gift ($$)
It happened a few days ago when my 6-max table busted and we were just heads-up. I didn't really want to play heads-up, but I humored him and crippled him with my nut flush vs. his turned pair of Ks.
Then I found that he was constantly at the fishiest tables. Coincidence? I think not. There've been times when the little leprechaun has bolted but many times he stays immediately to my right, donking off chips along the way.
Characteristics: He'll call any raise, call a flop bet but fold to a sign of strength on the river nearly all the time. He'll min raise pf with a monster and bet out something if he has it. It's like a dream.
It's times like these that make me glad to be playing online.
