The Complete Beginner’s Blueprint to Backgammon
Everything a newcomer needs to start playing with confidence: board anatomy, checker flow, entering from the bar, and bearing off fundamentals.
グランドマスターの黄金原則
Making the 5-point in your home board or opponent’s board should always be prioritized over wandering blots.
Never let your two back checkers on point 24 become isolated behind a developing opponent prime.
Accept doubles whenever your win equity is 25% or higher — dropping automatically forfeits 100% of the game value.
Do not leave accidental blots in your home board while bearing off if an opponent checker is lurking on the bar.
