In exceptionally simple terms, there are 3 basic techniques used. You need to be able to switch strategies almost instantly as the action of the game unfolds.
The Blockade
This is composed of building a 6-thick wall of checkers, or at least as thick as you can manage, to barricade in your competitor’s checkers that are located on your 1-point. This is deemed to be the most adequate procedure at the start of the game. You can build 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 locking your home board as fast as possible while keeping your opposer on the bar. e.g., if your competitor tosses an early two and shifts one piece from your 1-point to your three-point and you then toss a five-five, you will be able to play six/one six/one 8/3 8/3. Your opposer is now in big-time dire straits because they have two checkers on the bar and you have closed half your inside board!
The Backgame
This plan is where you have two or higher checkers in your opponent’s inner board. (An anchor spot is a position consisting of at least 2 of your pieces.) It needs to be employed when you are decidedly behind as it greatly improves your opportunities. The strongest areas for anchor spots are close to your opponent’s smaller points and also on abutting points or with a single point in between. Timing is integral for a competent backgame: after all, there’s no reason having two nice anchor spots and a solid wall in your own inner board if you are then required to break down this straight away, while your opposer is shifting their checkers home, seeing that you don’t have other additional pieces to move! In this situation, it is more favorable to have pieces on the bar so that you are able to maintain your position up until your opposer gives you a chance to hit, so it will be a wonderful idea to attempt and get your competitor to hit them in this situation!
