In astonishingly simple terms, there are 3 general techniques used. You must be agile enough to switch game plans instantly as the course of the match unfolds.
The Blockade
This is comprised of building a 6-thick wall of pieces, or at a minimum as thick as you are able to achieve, to lock in your competitor’s checkers that are on your 1-point. This is considered to be the most adequate tactic at the begining of the game. You can assemble the wall anywhere inbetween your 11-point and your 2-point and then shuffle it into your home board as the game continues.
The Blitz
This consists of closing your home board as fast as possible while keeping your opposer on the bar. i.e., if your challenger tosses an early 2 and moves one checker from your one-point to your 3-point and you then roll a five-five, you can play six/one 6/1 eight/three 8/3. Your competitor is now in serious dire straits taking into account that they have 2 pieces on the bar and you have closed half your inside board!
The Backgame
This tactic is where you have 2 or higher checkers in your competitor’s home board. (An anchor spot is a position consisting of at a minimum 2 of your checkers.) It must be played when you are extremely behind as it greatly improves your chances. The best places for anchor spots are close to your opponent’s smaller points and also on abutting points or with one point in between. Timing is important for an effective backgame: at the end of the day, there is no reason having 2 nice anchors and a solid wall in your own home board if you are then forced to dismantle this right away, while your opposer is moving their checkers home, because you do not have any other spare pieces to shift! In this case, it’s more tolerable to have checkers on the bar so that you are able to preserve your position up till your opposer gives you an opportunity to hit, so it will be a good idea to attempt and get your competitor to get them in this case!
