All backgammon players commit blunders.
Not all have the honesty and courage to point them out.

About his interesting position above, Ken said this:

I came in on the 5 and hit 16/15*. I was thinking that this put me up in the race and my opponent was threatening to make another point. Also, it would be harder to attack me with 4 checkers back. I was WAY wrong...

However, if you make one tiny change to the position... :)
