Analysis - same hand - version 2:
Having just posted it and read through it there were two conflicting thoughts running through my head
1) He could have had KJ and it's not in my range
2) Do not add hands in later streets after you have ruled them out in an earlier street.

So, I posted as is, went for a thinking and came to this: If your assumptions are wrong your results will also be wrong. Namely, this villain may very well be positionally aware and have a wider range on the button than in another spot. He may very well have noticed I have a high agression factor and thus is likely to stack off - an even wider range.

So, PokerStove on ranges - version 2:
PF: Any pocket pair. Any two broadways including ATs-JTs, ATo, QTo, JTo but not KTo. Suited connectors down to 87s. Suited one-gappers to J9s. Actually, let's throw in KTo for good measure. This gives us 19.2% of hands that a guy with 25/12 would call a standard raise with when he's on the button and knows the raiser is a bit aggro. Suddenly all too plausible.

(did PF wrong in version 1 - I took out AA etc already and should have left them in)
PF Equity:
QcJs: 42.18%
22+,ATs+,KTs+,QTs+,J9s+,T9s,98s,87s,ATo+,KTo+,QTo+ ,JTo: 57.82%

Flop Equity:
QcJs: 68.39%
JJ-22,AJs-ATs,KTs+,QTs+,J9s+,T9s,98s,87s,AQo-ATo,KTo+,QTo+,JTo: 31.61%

The flop still favours me! A bit. Now we need to take out any hand without a J or K or straight draw as they would have folded. And we have to take out many J (except JJ and KJ) hands as they would worry about only having two pair and might raise to keep drawing hands out. KT and KQ would also raise as it does not have a straight draw and would be outdrawn by it.

This leaves AQo, AT, QT, T9s as drawing hands and KJ and JJ as made hands in the range.

Turn Equity:
QcJs: 64.76%
JJ,ATs,KJs,QTs,T9s,AQo,ATo,KJo,QTo: 35.23%

Ok, now I'm confusing myself. I thought by the more generous definition of broadway hands I was including more hands in the villains range that could cause me worry. Did I just include more hands in the range that are 4-outers and thus increase my equity while carefully cutting out all hands that pair the J as they would have raised even if those were the hands I was worried about?
