Doesn't the fact that his AA hand has to include a spade change that? Supposes it also affects his AK range too.

I dunno maffs tho. Will hav to show workings.

Yup, a bit too rash there. Point is that for every hand that's unaffected by the board or our hand, the % is 50% (TT-KK/KQ etc.). For the other AA and AK/AQ, things change a bit to the worse: 5 of the remaining 8 AK combos have a spade (A[img]/images/graemlins/spade.gif[/img] K:any:, A[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/spade.gif[/img]), same for AQ. However, that only changes 50% to 62%. So if you include QQ etc. where it's exactly 50%, for all practical purposes of "live decision making" 50% is still good enough.
