Reads - I don't have PT up and running on this comp, and it's a bit tough for me to pick up too many reads while 6-tabling, aside from some very basic reads I've not quite gotten any either of these guys yet, so just assume no reads for this hand.

Considering how coordinated the board was, and how likely the turn was, in retrospect I feel like this may have been a good spot to lead out. The river completes the straight draw, as well as any backdoor draw, which sort of scared me off of a possible value bet--though this may very well be a leak of mine. So how'd I do on each street?
