play tic tac toe
Always start with X in a corner. If your oppenent puts on middle, it's most
probably a tie. All others, you win (the number next to the X / O represents
the order):
1.
02| |X3
|X2|O
X1|O1|X
2.
X1| |O
O2|O1|
X2|X3|X
3.
O2|O |X3
|X2|
X1|O1|X
4.
O | |X2
|X3|02
X1|O1|X
If he puts O in the middle, you can only hope for him to make a mistake,
or you'll tie.
If you go second, you can only hope for your opponent making a mistake.
If you can't, try for a tie !
