To wrap this all up, some of the work here got distilled into a fully playable game with adjustable strength, autoplay, hint system, and realtime perfect evaluation of any position. There is even a puzzle mode with difficult problem positions.

Have a look at the following link:

A full featured 4x4 Tic Tac Toe Game

The image shows an example game with both sides set to manual and hints enabled. X has to move and can win by playing the upper left corner. A move near the center will lose, and a move on the other corners will keep the game tied under optimal play. With hints disabled, all empty fields are white (and the player is in the dark).
