Wbridge5 was second (85.07), followed by Micro Bridge (81.53) and Q-Plus Bridge (74.51). The semifinals are tomorrow, December 6, pitting Synrey Bridge (+5.9 carryover) against Q-Plus Bridge and Wbridge5 (0 carryover) against Micro Bridge.

The law of total tricks was accurate on board 2 of the first round robin match. With 12 diamonds in the N-S hands and 9 spades in the E-W hands, 10 tricks can be made by each side and E-W will likely make 11 tricks in spades as a heart lead is unlikely.

Some CoC:
For a carryover into semifinals and final matches, a bot must both win its head-to-head round robin match against its, and finish ahead of its opponent in the round robin standing. The carryover is then the lesser of the VP difference in the round robin standings and the head-to-head match.
