2 HU $2 + .15 End 2nd 40 hands.

Mixed play on my part with poor play on the last hand. Had a nut flush draw after the flop and couldn't let go of it, even after I missed on the River.

I'm BB w/Ks 9s and 1075 chips. Blinds are 25/50. SB open raises 2 BB (100) and I call. Flop 3d 10s As. My mouth starts watering to see a nut flush!! I bet 100 into the 200 pot and the SB raises to 200. I call. I'm wondering if they might have the flush draw as well or just hit the Ace on the flop. Turn 4d. I check and SB bets 400 into the 600 pot. I call and only have 425 chips left. There was no good reason for me to call there, though pot odd wise it is 2.5 to 1 for me. River 9h. I have no place to go here and check, SB goes all-in w/1175, and I call. I just sort of gave up here and felt too lazy to continue play w/425 chips and just wanted to get this session over. Not a good sign for my poker playing tonight!!
