Starting out
Pieces are stronger in stacks. This gives you more strength and more options. So, in your opening moves, start putting your pieces in stacks of three or four, and get ready to move them toward your opponent's pieces. But take care to avoid putting your own stacks in harm's way of your opponent's stacks!
And remember that your pieces start out in a solid defensive position. So when you begin to set up your offense, you inevitably create weaknesses in your defense. When you do create your initial stacks, make sure they are still in a position to defend your remaining pieces.
When you have built enough stacks to go on the offensive, select one of your stacks that is in position to reach one of your opponent's pieces. Use a multi-step turn to cover that opponent's piece. Congratulations, you have made your first capture!
If you are unfortunate enough to have your opponent make the first offensive move, use one of your stacks to recapture your lost pieces. With any luck, you will minimize your losses.
Continuing play
As the game progresses, players will have pieces all over the board, in stacks of varying heights. Remember to keep many of your pieces in stacks because lone pieces are easily picked off by opponent's pieces.
Also, you may want to focus on building stacks of eight pieces. Since eight is the maximum height of any stack, when you control an eight-piece stack, that stack is invincible as long as you want it to be.
Remember, offense is much more difficult than defense! A poorly planned offensive turn can end up losing more pieces than it gains.
Ending the game
If you are winning the game, the fastest way to finish it off is to assemble several stacks, each made up of four of your pieces, and place them at various places around the board. You will then have no trouble mopping up the last few of your opponent's pieces.
