In exceptionally general terms, there are 3 fundamental techniques used. You need to be agile enough to hop between game plans almost instantly as the course of the game unfolds.
The Blockade
This is comprised of creating a 6-deep wall of pieces, or at a minimum as deep as you might manage, to lock in the competitor’s pieces that are located on your 1-point. This is judged to be the most acceptable procedure at the start of the match. You can assemble the wall anywhere inbetween your 11-point and your 2-point and then move it into your home board as the match continues.
The Blitz
This consists of locking your home board as quickly as as you can while keeping your opposer on the bar. i.e., if your competitor rolls an early 2 and moves one piece from your one-point to your three-point and you then roll a 5-5, you will be able to play 6/1 six/one 8/3 8/3. Your opposer is now in serious calamity seeing that they have 2 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 inner board. (An anchor spot is a point consisting of at a minimum two of your checkers.) It needs to be used when you are significantly behind as this plan greatly improves your chances. The best places for anchor spots are near your competitor’s lower points and also on adjacent points or with a single point in between. Timing is integral for an effectual backgame: after all, there’s no reason having two nice anchor spots and a complete wall in your own inner board if you are then required to dismantle this right away, while your challenger is moving their pieces home, because you do not have other spare checkers to shift! In this situation, it is more tolerable to have pieces on the bar so that you might maintain your position up until your competitor provides you an opportunity to hit, so it can be an excellent idea to attempt and get your opposer to hit them in this case!
