In exceptionally simple terms, there are 3 general tactics used. You need to be able to switch tactics instantly as the course of the match unfolds.
The Blockade
This involves building a 6-deep wall of pieces, or at a minimum as deep as you can achieve, to block in the competitor’s pieces that are on your 1-point. This is considered to be the most suitable procedure at the start of the match. You can assemble the wall anywhere inbetween your 11-point and your 2-point and then shuffle it into your home board as the game advances.
The Blitz
This involves locking your home board as fast as as you can while keeping your opponent on the bar. e.g., if your challenger rolls an early two and moves one piece from your 1-point to your 3-point and you then toss a five-five, you can play 6/1 six/one 8/3 8/3. Your opponent is then in big-time trouble taking into account that they have two checkers on the bar and you have locked half your inner board!
The Backgame
This strategy is where you have 2 or more anchors in your opponent’s home board. (An anchor is a position consisting of at least 2 of your pieces.) It would be employed when you are extremely behind as this plan greatly improves your opportunities. The best areas for anchor spots are towards your opponent’s lower points and either on abutting points or with a single point separating them. Timing is integral for an effectual backgame: besides, there’s no reason having two nice anchors and a complete wall in your own inner board if you are then forced to dismantle this straight away, while your opposer is moving their pieces home, because you do not have any other additional pieces to shift! In this case, it’s better to have checkers on the bar so that you might preserve your position up until your opponent gives you an opportunity to hit, so it will be a good idea to attempt and get your challenger to get them in this case!
