Here is a position that I got right purely from a gut feeling which comes from years of experience. It just felt wrong to leave a gap there on the 3 pt even though I had no idea why. Upon analysis it turns out that any move other than the first one is a blunder. It would be -.128 to take 2 off. I had no idea I had averted a possible huge loss of equity.

1. Cubeful 2-ply 8/6(2) 5/3(2) Eq.: +0.755
0.877 0.078 0.002 what are these numbers? (87.7% wins) 7.8% wins gammon, .2% backgammon

2. Cubeful 2-ply 8/6(2) 2/off(2) Eq.: +0.626 ( -0.128)
0.813 0.149 0.005

3. Cubeful 2-ply 8/6 5/3(2) 4/2 Eq.: +0.586 ( -0.169)
0.793 0.065 0.002

4. Cubeful 2-ply 8/4 5/3(2) Eq.: +0.554 ( -0.201)
0.777 0.068 0.002

Even though I did end up losing this match, my rating for this last game was "World Class" so it felt good. Even better than a win
