straight flush not frikking good enuff?

A while back, I was in a low ball buyin, 5 dollar affair with SuitedPockets, and of course we are playing at Absolute. I am in the cutoff with wired 6s, and I raise it up a couple blinds to go, the blinds were at 30 60, I believe, and the one limper calls, as the blinds and button folds. My stack is roughly 3 grand and the limpers is around 4. the flop is 78 clubs, and I have the 6 of clubs, and another six. I check, cause I do that sometimes, and the limper bets at me 3 blinds, and I smooth call
The pot is somewhere around 800 chips. The turn is the 5clubs, and Im really liking the board. The limper bets another 5 blinds, and I am starting to worry the str8 and flush, but I make another smooth call. Well the river comes as the 9 clubs, and im like sweeeeet, the limper bets the pot, and I am so over the top of that, and sure enuff he shows jack ten clubs, and im cursing myself, and congratualting him on a nice frikking hand

yeah i would have probably just called on the chance he had that one card but still you were unlucky that he did
