Before we start label the board in your head. Across the top is A through J, and down is 1 through 10.
Your first move is to put your piece at 4D, which should be diagonal to the top left of the top piece you start off with.
Next, put one directly to the right of that one, at 5D.
Now, block the computers diagonal at the bottom, most likely at 4G.
Then block the diagonal at the top. Which will either be 8C or 9B
Now put one in 6D, so that you have three in a horizontal row, after that put one in 4F to make a diagonal line of three.
The computer should move into the hole at 4E, then you can put a piece at 7C, then on the next turn add your fifth piece!
If the computer doesn’t move to 4E you can still do the same thing, or your can put your piece into 4E and have your five in a vertical line instead of diagonal!
This method should work about nine out of ten times. If it doesn’t work you can try a hand at solving by yourself, and if you die don’t sweat it.. chances are that you’ll win all the other matches anyways! – _sakkie_
