In extraordinarily general terms, there are 3 general tactics employed. You must be able to hop between strategies quickly as the course of the game unfolds.
The Blockade
This consists of assembling a 6-thick wall of checkers, or at least as thick as you can manage, to barricade in your opponent’s pieces that are located on your 1-point. This is considered to be the most adequate course of action at the start of the game. You can create the wall anywhere within your 11-point and your 2-point and then shift it into your home board as the game advances.
The Blitz
This involves closing your home board as quickly as as you can while keeping your challenger on the bar. i.e., if your challenger rolls an early two and moves one piece from your 1-point to your three-point and you then roll a five-five, you can play six/one 6/1 eight/three eight/three. Your competitor is now in serious calamity because they have 2 checkers on the bar and you have locked half your inside board!
The Backgame
This strategy is where you have two or more anchors in your competitor’s inner board. (An anchor is a position consisting of at a minimum two of your pieces.) It must be played when you are significantly behind as it greatly improves your circumstances. The best locations for anchors are near your competitor’s smaller points and also on adjacent points or with one point separating them. Timing is crucial for a powerful backgame: at the end of the day, there’s no reason having 2 nice anchors and a solid wall in your own inner board if you are then forced to break down this straight away, while your challenger is moving their checkers home, considering that you don’t have any other spare checkers to move! In this situation, it’s more tolerable to have checkers on the bar so that you are able to preserve your position up till your opponent provides you a chance to hit, so it may be a great idea to attempt and get your opponent to get them in this situation!
