In extraordinarily general terms, there are three fundamental techniques used. You want to be able to hop between game plans almost instantly as the action of the match unfolds.
The Blockade
This is composed of building a 6-deep wall of pieces, or at a minimum as deep as you might manage, to block in the competitor’s pieces that are on your 1-point. This is considered to be the most acceptable strategy at the start of the match. You can create the wall anywhere inbetween your 11-point and your 2-point and then shift it into your home board as the match advances.
The Blitz
This involves locking your home board as quickly as possible while keeping your opponent on the bar. i.e., if your opponent tosses an early 2 and moves one checker from your 1-point to your three-point and you then toss a 5-5, you can play six/one 6/1 8/3 8/3. Your challenger is now in serious difficulty taking into account that they have two pieces on the bar and you have locked half your home board!
The Backgame
This plan is where you have 2 or higher checkers in your competitor’s inner board. (An anchor is a point consisting of at a minimum 2 of your pieces.) It would be played when you are decidedly behind as it greatly improves your circumstances. The best places for anchor spots are close to your opponent’s lower points and either on abutting points or with one point in between. Timing is critical for an effectual backgame: besides, there’s no reason having two nice anchor spots and a complete wall in your own inner board if you are then required to break up this straight away, while your opponent is moving their checkers home, considering that you do not have any other additional pieces to shift! In this case, it’s more tolerable to have pieces on the bar so that you might maintain your position until your opponent provides you an opportunity to hit, so it will be a great idea to try and get your challenger to hit them in this case!
