Basically, there are three bonuses for two-handed weapon use:

1) Two-handed paladin dedicate.
2) Trapping Beneath Thunder (for either two-handed or one-handed heavy weapons)
3) Generic heavy two-handed weapon bonus.

You get the most favorable of the three. #1 and #2 are preferable to #3, though not by a great deal.

The Mamlauk adapation skill Brute Force stacks with any of the above, which cranks that path up a bit. (Particularly Mamlauk orc paladins with Legacies. Good luck with that.)
