Not sure if all of this applies to Pathfinder but...
You're concept of an intelligent fighter is not bad, but you'll be hard-pressed to say it's effective as well.
Nothing is bad about it in flavor or theory, but mechanically these are some of the problems:
1. Sword and board in a typical 3.x game is a horridly inefficient fighting style. If you have a source of bonus damage (like skirmish or sneak attack or sudden strike), it's a good idea to wield two weapons because it increases your chances to scoop up handfuls of d6's. Everyone else typically goes with a two-handed weapon because you get 1.5x strength bonus do damage and double your penalty on Power Attack to damage. Just by the written rules your abilities are working extra without you having to really do anything. Sword and board has no such benefits, and as was mentioned in another thread recently, you wind up spending character building resources on not sucking rather than being awesome. I recall there was a "Captain America" build from the older boards that actually made use of just the shield in combat and was better with just that than a sword and shield.
2. You say you want to have an "intelligent" fighter. That's fine, but your concepts don't really extend beyond making smart tactical decisions that increase your chances of winning which, frankly, any character could and should do. It's just that you don't have anything that really makes your Intelligence work for you in combat. It's just sitting there not providing you anything that will save your life beyond your own ingenuity as a player. This goes back to using character resources on not sucking since you have to do extra work to get UMD as a class skill and overcome your Charisma penalty.
Now, for instance, if you take the Knowledge Devotion feat you roll Knowledge checks to get bonuses to attack and damage for the rest of combat. Now your intelligence is doing something. A swashbuckler can add his Intelligence modifier to damage rolls in addition to strength. A Factotum can do almost everything with Intelligence, and in fact would likely fit the concept of an "Intelligent fighter" much better than a straight Fighter with a high Intelligence score would.
I'm not trying to tell you your idea is bad or how to play your character, but you should be aware that how effective your character will be will depend on the optimization level of the group. Aside from Use Magic Device, you could very easily see your character become marginalized to the point of useless in combat and not have anything meaningful to contribute.
