Match points, ACBL robot individual

I'm wondering how total points are computed. In the attached hand, the system notes attributed "7-10 total points" to North for its 3♥ bid. With 10 HCP, 4-card trump support with a doubleton, two Aces (including the Ace of opener's suit)and two 10s to boot, I would consider North's hand much closer to a 4♥ bid; and if not 4♥, then a mandatory 2♠ call. Note that 18 of 22 South players were fooled by the underbid.

GIB is overly cautious in calculating total points. It's HCP plus 3 for a void, 2 for a singleton and 1 for a void, MINUS 1 for any suit in which it counted both HCP and shortness. So, Ax is only worth 4 total points, and tens are never considered, nor is extra length. Conversely, GIB overcounts by including points for shortness in partner's bid suit.

HCP vs Total Points

Gib uses both old fashioned HCP (A=4, K=3, Q=2, J=1)) and “Total points” (HCP+3 for void, 2 for singleton, 1 for doubleton, but short suits containing an honor are reduced by 1 point). It will usually force to game if it thinks it has 25 Total Points between the two hands.

I don't know for sure, but I hope 4♥ would have been an inappropriate preemptive raise; 2♠ would be the strong raise.

as the cards lie 4♥ makes but if ♦ split 4-2/5-1 a ruff is a danger
