In very general terms, there are three general techniques used. You need to be agile enough to switch tactics quickly as the course of the match unfolds.
The Blockade
This consists of assembling a 6-deep wall of pieces, or at least as thick as you might achieve, to block in your competitor’s checkers that are on your 1-point. This is judged to be the most suitable strategy at the begining of the match. You can assemble the wall anywhere between your eleven-point and your 2-point and then shift it into your home board as the match continues.
The Blitz
This is composed of locking your home board as fast as possible while keeping your opposer on the bar. e.g., if your challenger rolls an early 2 and shifts one piece from your 1-point to your three-point and you then roll a five-five, you are able to play six/one six/one eight/three eight/three. Your challenger is now in big-time trouble considering that they have two checkers on the bar and you have closed half your inside board!
The Backgame
This tactic is where you have two or more checkers in your competitor’s inner board. (An anchor spot is a point filled by at a minimum two of your checkers.) It must be played when you are extremely behind as it greatly improves your opportunities. The better places for anchors are close to your competitor’s smaller points and also on abutting points or with a single point in between. Timing is important for a powerful backgame: at the end of the day, there’s no reason having 2 nice anchors and a complete wall in your own home board if you are then forced to dismantle this straight away, while your opposer is getting their pieces home, taking into account that you do not have other spare checkers to move! In this case, it’s better to have pieces on the bar so that you might maintain your position up until your challenger gives you a chance to hit, so it can be a good idea to attempt and get your challenger to get them in this case!
