I guess the question would be, can you beat the computer when you go second? If it can't beat you in that case you probably need a better program
I had to do a connect 4 program in college. It was pretty good but it wasn't the best program in class (though it did decently against the other programs). My algorithm wasn't the best but it played a pretty good game.
connect 4 is a fun little game.but connect 4 has been solved in 1988 with perfect play the player going first can force a win by starting in the middle.
I have read the strategy and can now beat the computer even at best level almost every time. the strategy is almost easy to a chessplayer control the middle and you control the game. by controlling the middle you have a lot of changes to connect 4.
always place pieces that increases your changes to connect 4 the most.
Do you still want to play the game going second?
