In exceptionally simple terms, there are 3 main techniques used. You want to be agile enough to hop between tactics quickly as the course of the game unfolds.
The Blockade
This involves creating a 6-deep wall of checkers, or at a minimum as thick as you can manage, to barricade in your opponent’s pieces that are located on your 1-point. This is deemed to be the most acceptable tactic at the begining of the match. You can create the wall anyplace between your eleven-point and your two-point and then move it into your home board as the game continues.
The Blitz
This involves locking your home board as quickly as as you can while keeping your challenger on the bar. e.g., if your opponent tosses an early two and shifts one checker from your 1-point to your 3-point and you then roll a five-five, you can play 6/1 6/1 eight/three 8/3. Your challenger is then in serious dire straits seeing that they have 2 checkers on the bar and you have locked half your inner board!
The Backgame
This plan is where you have 2 or higher checkers in your opponent’s home board. (An anchor is a point consisting of at a minimum two of your pieces.) It would be employed when you are decidedly behind as this plan greatly improves your opportunities. The strongest areas for anchors are towards your competitor’s smaller points and either on adjoining points or with one point separating them. Timing is essential for a competent backgame: at the end of the day, there’s no point having 2 nice anchor spots and a complete wall in your own home board if you are then required to break down this straight away, while your opponent is moving their pieces home, because you do not have any other extra pieces to move! In this case, it is more tolerable to have checkers on the bar so that you might maintain your position until your challenger provides you an opportunity to hit, so it may be a good idea to attempt and get your competitor to get them in this case!
