Knight 6/ Crusader 14 Build

[Doom 364]

Hello, I'm new to the site and fairly new to D&D. I am making a character for an adventure path, and I am going to be the primary tank. My idea was to go Knight 6/ Crusader 14, and using a spiked chain + enlarge person (supplied by the party Conjurer) to increase my coverage of the grid in conjunction with the knight's third level ability to turn threatened squares into difficult terrain and the devoted spirit stance, Iron Guard's Glare, to persuade enemies to attack me.

I am wondering if The Shield Ally ability for Knight is very good, what other maneuvers and stances would be helpful, if I should use a different level split, if any other classes would be helpful, what feats would be helpful, if I should go Dwarf or some other race, or anything else that might help.

Thank you in advance!

I'd go human, as you may find the extra feat useful.

It will definitely pay to take Combat Expertise and Improved Trip, along with Combat Reflexes, Stormguard Warrior, and Robiliar's Gambit.

The Crusader's Handbook has more information.

While Iron Guard's Glare is pretty good to make yourself more of a target, consider the Thicket of Blades stance: every kind of movement provokes AoOs from you, even a 5' step. That one stance makes the Knight's abilities pointless, leaving you free to go Crusader all the way (not a weak class at all, way better than Knight IMO).
Combined with the Stand Still feat, you can make sure nothing that enters your threatened area ever gets out unless they kill you first. Which may be difficult if you're large and have a reach weapon, since they can't easily get to you...
Later on, Robilar's Gambit ensures you get even more AoOs. Make sure to take Combat Reflexes early, and pump that Dex score!
