The Opening Move
When playing as the first player you should start with the 3rd cup as your opening move. This will ensure that your last seed lands in your capture pit.
This serves to provide two benefits; It gives you a point in the form of a capture and it also gives you an extra bonus turn because your last seed landed in your own capture pit.
Now play from the cup nearest or even the second nearest to your capture pit. Either of these moves will drop a seed into your opponents 3rd cup removing their ability to use the same opening move.
