1) JJ is 56.1% PF against AK, so I expect it to hold up and be +EV over time.

2) This isn't running good, it's expected +EV. Your set is 70.2% on the flop.

3) Now you're on the bad side of the coin flip, as you are only 44% against QQ. If this holds up repeatedly, you've got positive variance, which would contribute to running good.

Anyway, what others said. Look at your win rate, and if it's abnormally high over a decent period of time, you're running good.

Cheers
