Mute,
Thanks for your concern, but my bankroll is fine. My day was kind of like yours:
In the set hand, when she flat called the flop I put her solidly on a straight draw + a backdoor low (I'm not kidding), and I didn't want to get raised off my set on the turn. The river call was on the chance she'd sometimes be bluffing (and curiosity - I have no idea how the 1K plays).
In hindsight the I was probably playing a bit cautiously. Note that "shoving" the turn wasn't an option though - I had ~850 behind and the pot was $200.
And thanks for the invite - after watching you today I'll be glad to have you at my table.
