I am just not at all sure why it ruffed the first Spade high, when there was no risk of an overruff, and the second Spade low, when there was. Someone will no doubt put me right.

What I still don't understand is why it always wants to play high cards when it's not necessary. At trick 1 it ruffs high, and at trick 2 there's no reason at all to play ♣9 to the Ace, you might even need it later on. Nevertheless it wastes 2 possibly valuable high trumps. Shouldn't it be basic coding to avoid this?

Gib doesnt seem to be really a decision making entity. It just simulates lots of hands. Once it discovered that the trumps were 4-0 it started playing for the most likely layout, which it apparently thought that there was no chance of an over-ruff. I.e., it must have originally included hands where clubs were 2-2 with Q on teh right, but after trumps are 4-0 it is only playing for holdings where there is no chance of an overruff so the choice of club is random.

I would have thought that the more Clubs were held by LHO, the greater would be the chance of that hand having Spade short and thence be in a position to overruff. Spade short is likely anyway on the bidding, but shorter still.

Aaron - as far as I can tell your example hands were played against "basic robots" that you rented using the web-client.
If the money is not an issue for you and if you care about the quality of your GIB partners and opponents, I strongly suggest you rent the "advanced robots" instead. I think you will find that there is a dramatic difference.
