As I said at the time, it is unbelievable that anyone can pass this position at this level of play

Nerves and gammonphobia strike again. Mochy's cube here is much too soon for the score, and Lars' pass is likely the worst of his great career. This one game ruined both players ER's. Play was exceptionally good in the early/mid match but then deteriorated. Lars' cube play when trailing was far off the mark as he missed many fine score based doubling opportunites and then made the unbelievable pass. Nerves, pressure, fatigue all factor in, and for me it is usually the fatigue that gets me.

The score (after 0 games) is: Mochy 21, Lars 14 (match to 25 points)

Move number 4: Mochy on roll, cube decision?
