In very simple terms, there are 3 fundamental tactics used. You need to be agile enough to hop between strategies instantly as the action of the match unfolds.
The Blockade
This consists of building a 6-thick wall of checkers, or at a minimum as thick as you might manage, to barricade in your competitor’s checkers that are located on your 1-point. This is judged to be the most suitable procedure at the start of the match. You can build the wall anywhere between your 11-point and your two-point and then move it into your home board as the game progresses.
The Blitz
This consists of closing your home board as fast as as you can while keeping your challenger on the bar. i.e., if your competitor rolls an early two and shifts one checker from your 1-point to your three-point and you then roll a five-five, you are able to play 6/1 6/1 8/3 8/3. Your challenger is now in big-time dire straits due to the fact that they have 2 pieces on the bar and you have locked half your inner board!
The Backgame
This strategy is where you have 2 or higher anchors in your competitor’s home board. (An anchor spot is a point consisting of at least 2 of your checkers.) It should be used when you are extremely behind as it much improves your chances. The better locations for anchors are towards your opponent’s smaller points and either on adjoining points or with a single point separating them. Timing is crucial for a competent backgame: besides, there is no point having two nice anchors and a complete wall in your own inner board if you are then required to break up this right away, while your competitor is shifting their pieces home, owing to the fact that you don’t have any other spare checkers to move! In this situation, it is better to have pieces on the bar so that you are able to maintain your position up until your opponent gives you a chance to hit, so it will be a good idea to try and get your challenger to get them in this situation!
