In exceptionally general terms, there are three main techniques employed. You want to be agile enough to switch techniques quickly as the action of the game unfolds.
The Blockade
This involves creating a 6-deep wall of pieces, or at least as deep as you are able to achieve, to block in the opponent’s pieces that are located on your 1-point. This is considered to be the most suitable course of action at the begining of the match. You can assemble the wall anyplace between your 11-point and your two-point and then shift it into your home board as the game progresses.
The Blitz
This consists of locking your home board as quick as as you can while keeping your challenger on the bar. e.g., if your opposer rolls an early two and shifts one piece from your one-point to your 3-point and you then toss a 5-5, you will be able to play six/one 6/1 8/3 8/3. Your challenger is then in serious dire straits because they have 2 pieces on the bar and you have closed half your home board!
The Backgame
This plan is where you have two or more checkers in your opponent’s inner board. (An anchor spot is a point consisting of at a minimum two of your checkers.) It should be used when you are decidedly behind as this plan much improves your circumstances. The strongest locations for anchor spots are towards your opponent’s smaller points and either on adjacent points or with one point in between. Timing is crucial for an effective backgame: besides, there’s no point having two nice anchors and a complete wall in your own home board if you are then required to dismantle this straight away, while your opponent is getting their checkers home, because you do not have any other extra pieces to move! In this case, it’s better to have pieces on the bar so that you might preserve your position up until your challenger gives you an opportunity to hit, so it will be a wonderful idea to try and get your competitor to get them in this situation!
