tic tac toe

trumpler (13)
so in the midst of creating this tic tac toe game,i have this problem.it goes like this.
TURN 1
when the player picks the number 4,the computer will choose the number 2.
and when the player picks anything other than 4,the computer will choose 4.
TURN 2
the computer will try to intercept you to prevent you from winning.

so the problem is that when i pick any number other than 4,the computer will not choose 4 but instead jump to the options in turn 2.i cant seem to figure out why.

One problem are the braces of the if on line 102. The if body contains the second check of turn on line 121 which will never be true.
