In extraordinarily simple terms, there are 3 general techniques employed. You want to be able to switch game plans almost instantly as the action of the match unfolds.
The Blockade
This is comprised of building a 6-thick wall of checkers, or at least as thick as you can achieve, to block in the opponent’s checkers that are on your 1-point. This is deemed to be the most adequate tactic at the start of the match. You can assemble the wall anyplace within your 11-point and your 2-point and then shift it into your home board as the match advances.
The Blitz
This is comprised of closing your home board as quickly as possible while keeping your competitor on the bar. i.e., if your challenger rolls an early 2 and moves one checker from your one-point to your three-point and you then toss a five-five, you can play six/one six/one eight/three 8/3. Your opponent is then in serious trouble taking into account that they have 2 pieces on the bar and you have locked half your inside board!
The Backgame
This plan is where you have 2 or higher checkers in your opponent’s home board. (An anchor spot is a position consisting of at least two of your checkers.) It needs to be played when you are extremely behind as this strategy greatly improves your chances. The best areas for anchors are close to your competitor’s smaller points and also on adjoining points or with a single point in between. Timing is essential for a competent 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 apart this straight away, while your competitor is moving their pieces home, because you do not have any other spare pieces to shift! In this case, it is more favorable to have pieces on the bar so that you are able to preserve your position until your opposer provides you a chance to hit, so it may be a great idea to try and get your challenger to get them in this case!
