My moneys on them putting you on ak or aq and then callin you down. Thats what i usually tell myself, and it tends to lessen the affect of the bad beat. Also, im betting he took your 1700 bet on the flop (4+ times original raise) as an attempt to buy your way out of not hitting. After he made that wrong assumption, he got lucky, yea. dont know ur style, but if u play loosely thatll happen a lot. I find that if i tighten up my play (for the table image), in that same situation I bet 1/3 or 1/2 my stack (usually a multiple of my initial bet), and ppl would give me credit and fold there. Anyways tough break, but like mark said, gotta get that helmet :-p
