PS 2 HU $2 + .20 Lost

I closed out Poker Stars too soon so can't check back on hands. The match went on too long and I was ahead for much of it. As we got to the end, I noticed I was tired and started playing to play and overextending my hand possibilities. Say I have JJ and the flop shows an Ace. I kept betting the J's. Last hand I had a flush draw, flop had two 9's. Other player raised my bet and I called thinking they might have that 3rd 9. They tended to fold when I bet, so fi they raised that indicated they might have something. I continued to bet and go all-in. They won. They had the 9. Time for me to stop playing!
