Jason Almost Folds the Nuts, Hilarity Ensues

Putting the title of the post aside for a moment, I've played 10k hands already in May, adding $515 cash and ~$110 in FPPs to my roll. I ran above average during my Saturday session, but below average during my hands on Sunday. Overall, when considering both showdown equity and heater versus cooler hands, I believe I've run marginally hot (probably ~0.5 ptBB/100 better than average) which seems about right since I'm at 4.7ptBB/100 on the month so far.

Below is my EV graph for the weekend:


As per the title, here is a hand where I was the Big Blind, and almost folded the nuts on the river. My river check was unintentional, I wasn't aware of the hand I had at the time. Since there had been no betting up to the river and I had action going on with premium hands at other tables, I was basically in "check/fold" fold mode on this table barring making something like trips or two pair. Just before I hit the "fold" button on the river, I did a quick double take and noticed I might have a straight, and I'll be damned, I had the nut straight infact! The hand was so well disguised I almost didn't even notice I had it.

I'll have two more hand history posts coming either later in the day or tomorrow, which will be much more educations. One will deal with bluffing the river, and the other with the benefits of taking notes on players and trusting these reads when appropriate.
