I was reasonably sure that I was facing some sort of decent QQ or KK hand here, and since I wasn't worried about being punished on future streets, I went for it.

Was I too loose here, or did I do the best that I could with a slightly oddball scenario? (I called preflop because the odds of spiking a jack justified calling a minraise with a lot of loose donks in the pot.)
