People who think they are better wrestlers/strikers than him (or think they'll tool him on the ground) but in fact cannot overpower him. For instance he destroyed the physically weaker Cyrril Abbidi (sp) 2 times in K1 (thats right not even in mma and almost completely without clinch), who has beaten Peter Aerts 2 consecutive times, simply with power combined with technique.
People who can overpower him standing up using knees (Chuteboxe is bad matchup for him since the knee's force>the punch's force, and Rampage usually punches). Especially iof he gets hurt/overpowered in the clinch.
But even against a bad matchup he has a very good chance compared to other fighters of winning against that matchup IMo, since he's such an oppurtunitist with such power.
I can't argue with the analysises above.
