Nothing exciting here but OtB I'd bet at least 99% of the players would
miss this.

       X rolls 4-2.

Unless O rolls something like 2-1 followed by 3-1, then X will need doubles
to win the game.

Yep, I make this error playing too fast.  More efficient bear off with
doubles if you bear one off and stack the 2 point.

Stein Kulseth  writes:

4/2, 3/off makes 2-2 work next roll.  Nice position.

Rich Munitz  writes:

To be honest I hadn't even thought it possible that it could ever be right
to not bear off two checkers with non-doubles, unless filling a gap from a
stack. And it is even more surprising that it could be right to do so while
wasting a pip.

What's different here is that sacrificing one checker (and one pip) now
when we are now odd, creates the possibility of taking two more checkers
off next roll.

A rare aligning of the planets here.
