Flop-a-set-ometer

Flop-a-set-ometer is a program to see how lucky your are with flopping sets and set vs set situations (www.pokerluckometer.com). I really like it and especially when running good/bad it really gives you a good impression of how good you run.
In september I'm running not so good, although I flopped more sets then expected.
But I'm runnig very unlucky in big pots. For example when flopping a set with AA or 88 (which happened 8 times for both) I actually LOST money with it.

I also got dealt aces 62 times this month (expected 82) and got into a overpair vs set situation 8 times versus 2 times set vs overpair.
Over to the hand of the day:

This AA situation is really a good example of when to fold aces.
Villian in this hand is pretty tight and not really agressive, at least nothing out of line. He runs about 21/12/2.

BldZwtTrn checks

I check here because I think this opponent isn't calling with a lot of worse hands here when I bet. The only hand that I can get value from is 98/88 probably.

pandora28 bets $34.00
BldZwtTrn calls $34.00

He bets kind of small which makes me think he is either trapping or has a weak 7x/88/98 hand.

*** RIVER *** [6d 7s 3c 9c] [Qd]
BldZwtTrn checks

I'm not really sure if I like my check/call here. Against this opponent bet/folding is probably better, because he's never blufraising me here and I also think he will check all his mediocre hands behind but might call with it. Check/folding is also an option because I can't see much bluff hands here for him (most of them have some showdown equity and will check behind).
