I'm dumb

[Perestroika]

Can someone explain to me why this hand

http://twodimes.net/poker/?g=o&b=jd+...%0Aad+td+tc+qd

Has three percent higher equity than this hand, notice the difference is the 2d in the first hand and the 8d in second.

If anything I would assume that the 8d would increase his equity even higher than the 2d because having the eight takes away from possible straight flush redraws that villain holds and both the 2 and the 8 have equal chances of making hero a full house???
