In extraordinarily simple terms, there are 3 main plans employed. You need to be able to switch tactics quickly as the action of the match unfolds.
The Blockade
This consists of creating a 6-thick wall of checkers, or at least as deep as you can manage, to block in the competitor’s checkers that are on your 1-point. This is deemed to be the most adequate strategy at the begining of the game. You can build the wall anyplace between your eleven-point and your two-point and then shift it into your home board as the game advances.
The Blitz
This involves closing your home board as fast as as you can while keeping your opposer on the bar. e.g., if your opponent rolls an early two and shifts one piece from your one-point to your 3-point and you then roll a 5-5, you will be able to play six/one 6/1 eight/three eight/three. Your challenger is then in serious trouble because they have 2 checkers on the bar and you have locked half your inside board!
The Backgame
This strategy is where you have 2 or higher checkers in your opponent’s inner board. (An anchor is a point filled by at least two of your pieces.) It must be used when you are extremely behind as it greatly improves your circumstances. The best areas for anchor spots are close to your opponent’s lower points and also on abutting points or with one point in between. Timing is important for a powerful backgame: at the end of the day, there’s no point having two nice anchor spots and a complete wall in your own inner board if you are then required to break up this straight away, while your opponent is moving their pieces home, because you do not have other extra checkers to shift! In this case, it is better to have checkers on the bar so that you can preserve your position up until your opponent provides you a chance to hit, so it will be an excellent idea to attempt and get your challenger to get them in this case!
