How about a fighter who looks over his opponents instead of just rushing in? Here is the starter feat for the archetype.
Knowledge is Power
You’ve learned through experience or books what you need to do when.
Benefit: When you encounter a creature, you may make a knowledge check using the appropriate skill with DC equal to 10+creature CR. If you succeed, you gain a +1 to either attack, saves, or defense against the creature. These bonuses may be separated however you choose among attack, defense, and saves. The bonus gains by this power increases by +1 for every 5 you succeed by.
