In astonishingly general terms, there are 3 fundamental plans employed. You need to be agile enough to switch tactics almost instantly as the course of the game unfolds.
The Blockade
This involves assembling a 6-deep wall of pieces, or at least as thick as you can achieve, to barricade in the opponent’s pieces that are on your 1-point. This is considered to be the most suitable tactic at the begining of the game. You can build the wall anyplace between your 11-point and your 2-point and then shuffle it into your home board as the game advances.
The Blitz
This consists of closing your home board as fast as as you can while keeping your competitor 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 toss a five-five, you are able to play 6/1 six/one 8/3 8/3. Your opposer is now in serious dire straits 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 two or higher anchors in your opponent’s home board. (An anchor is a point filled by at a minimum 2 of your checkers.) It needs to be used when you are extremely behind as this strategy greatly improves your circumstances. The best areas for anchor spots are towards your opponent’s smaller points and also on abutting points or with one point separating them. Timing is integral for a competent backgame: at the end of the day, there is no point having two nice anchors and a solid wall in your own inner board if you are then required to break down this right away, while your opposer is shifting their pieces home, seeing that you don’t have any other spare pieces to move! In this case, it is more favorable to have checkers on the bar so that you can preserve your position up till your opponent provides you a chance to hit, so it may be a great idea to try and get your opponent to get them in this case!
