Has Connect-Four been solved?

Connect Four has since been solved with brute-force methods, beginning with John Tromp’s work in compiling an 8-ply database (February 4, 1995).

Can you always win Connect 4?

Connect Four is what mathematicians call a “solved game,” meaning you can play it perfectly every time, no matter what your opponent does. You will need to get the first move, but as long as you do so, you can always win within 41 moves.
