The turn is 7♦. I've got the nut low, so I try to figure out what I can bet to not scare others out. I go in for $1, and get one caller.
The river is 9♦. No flush possibility, so I bet the pot, $3.12. As the other player considers what to do, I come back to reality, and make the stark realization:
I don't have the nut low. I've got crap. A board of 4Q979 doesn't have a low possibility, and -- duh -- I can only use two cards from my hand, not the A, 2, and 3.
He decides I must have hit a full house with the last nine, and folds. I collect $3.12 and exhale.
It's time to start paying attention, lawyer boy.
Several hands later, I'm in late position, and get 2♠ J♠ T♠ 3♣.
The board comes A♦ K♠ 4♣. Again, I'm going for the nut low, one card to go, but this time, I'm awake enough to realize that I'm only using the 2 and 3 to get it. No, I'm not just one card away from a spade flush, I realize that. I make a minor raise to run off the riff raff.
The turn is 7♣, so I've made my nut low. I bet the pot, and have one caller.
The river is a safe looking Q♥, so I bet the pot again -- maybe I'll scare him off -- and he calls. I show the nut low, and he shows two pair, so we split the pot.
Except we don't. I get the whole pot. What the heck?
Yeah. That J♠ T♠ that I spent my whole hand ignoring? The queen on the river gave me broadway. Scooped pot of $3.17.
Wake up, lawyer boy. Wake up. Up $2.10 for the night.
