In exceptionally general terms, there are 3 main tactics used. You must be agile enough to hop between tactics instantly as the course of the game unfolds.
The Blockade
This is composed of assembling a 6-deep wall of checkers, or at least as thick as you can achieve, to lock in the opponent’s pieces that are located on your 1-point. This is deemed to be the most suitable strategy at the begining of the match. You can assemble the wall anywhere within your 11-point and your 2-point and then move it into your home board as the game progresses.
The Blitz
This involves closing your home board as quick as as you can while keeping your competitor on the bar. For example, if your opposer rolls an early 2 and moves one piece from your one-point to your 3-point and you then roll a 5-5, you can play six/one 6/1 8/3 eight/three. Your opponent is now in serious dire straits because they have two checkers on the bar and you have closed half your inner board!
The Backgame
This course of action is where you have two or more anchors in your opponent’s inner board. (An anchor spot is a position consisting of at a minimum 2 of your checkers.) It would be used when you are decidedly behind as it much improves your chances. The best locations for anchor spots are close to your competitor’s lower points and either on adjoining points or with one point in between. Timing is integral for an effectual backgame: after all, there is no point having 2 nice anchors and a solid wall in your own inner board if you are then forced to break apart this straight away, while your opposer is getting their pieces home, taking into account that you do not have any other additional checkers to move! In this case, it’s more tolerable to have checkers on the bar so that you might maintain your position up till your opponent gives you a chance to hit, so it can be a good idea to try and get your opposer to hit them in this case!
