2 HU $1 + .10 End 2nd 29 Hands

I was playing this to look at a PT HUD config I'm trying to work out. 1st I've tried to make my own. This was a dud test as I'd created a configuration for a cash session. That aside, I was doing OK until hand 13 when it looked like I'd do fine, though the Rver put it in doubt along with the other players all in raise to my 1/2 pot bet. I had QJo and between the Flop & the River I had top two pair. The River, though turned up a 3rd spade and indeed the BB had K7 of spades and I was down to 300 chips. I wasn't able to recover from that. I do feel I bet OK and doubt if I went all-in on him that that would have deterred him calling on the Turn.
