In extraordinarily general terms, there are 3 main tactics used. You need to be agile enough to hop between strategies almost instantly as the action of the game unfolds.
The Blockade
This is composed of assembling a 6-thick wall of pieces, or at a minimum as deep as you can achieve, to block in the opponent’s pieces that are on your 1-point. This is deemed to be the most adequate procedure at the begining of the match. You can assemble the wall anyplace inbetween your 11-point and your 2-point and then move it into your home board as the match advances.
The Blitz
This is comprised of closing your home board as quick as as you can while keeping your challenger on the bar. For example, if your competitor rolls an early 2 and shifts one checker from your one-point to your 3-point and you then toss a five-five, you are able to play six/one 6/1 eight/three eight/three. Your opponent is then in serious calamity seeing that they have 2 checkers on the bar and you have closed half your home board!
The Backgame
This course of action is where you have 2 or higher anchors in your competitor’s home board. (An anchor is a position filled by at least two of your checkers.) It must be played when you are significantly behind as it greatly improves your chances. The strongest places for anchors are close to your competitor’s lower points and either on adjoining points or with a single point separating them. Timing is important for a powerful backgame: besides, there is no point having 2 nice anchor spots and a complete wall in your own inner board if you are then required to break up this right away, while your competitor is getting their pieces home, because you don’t have any other extra pieces to shift! In this case, it’s more tolerable to have pieces on the bar so that you are able to preserve your position until your challenger gives you an opportunity to hit, so it will be a good idea to try and get your opposer to hit them in this case!
