GIB Frequently Asked Moscito Questions

GIB Moscito FAQ

Is GIB playing Moscito because we think its bidding is weak using standard methods? Hardly. As far as we can tell, GIB 3 is a substantially stronger bidder than GIB 2 was. It is still nothing like expert level, however; bidding is hard.
We're using Moscito in Bermuda because our fundamental goal from a skill point of view is to win the human world championships. We obviously can't guarantee what will happen in Bermuda, but we would expect GIB to be a strong favorite independent of its system choice.

Will implementing Moscito make GIB a stronger bidder using standard methods? Yes, curiously enough. One of the principal differences between GIB 3 and GIB 2 is that GIB 3 has a wide set of "default" bidding rules, saying things like "bid 3NT if you have the values, no fit, and no unstopped suits to worry about." The improved accuracy of the Moscito definitions should help us understand and debug these default rules, leading to general improvements in GIB's overall bidding (whatever system it's playing).

Is disclosure an issue in Bermuda? Of course. We will be happy to provide other contestants with disclosure at whatever level they want -- including a copy of the bidding database itself, if need be!
The conditions of contest in Bermuda allow ACBL mid-chart conventions. The version of Moscito being played by GIB has been carefully designed to conform to that restriction.

Have we analyzed the performance of Moscito-GIB? Not yet; it's not ready. As soon as it is, we'll launch it on OKBridge.

Will the Moscito database be available to GIB customers? Of course. We will implement Moscito as a system choice, and the database itself will be available as well. Distributing the database will probably happen around the same time we launch on OKBridge (around the end of the year). Making Moscito a system choice will involve a little bit of modification to the Java code and will take longer.

GIB's Moscito differs from the common versions in Australia. How was it constructed? GIB's Moscito is a combination of ideas from the original system, Moscito 2000, and a variety of suggestions from Bo-Yin Yang and David Morgan. The relay structure comes from Bo-Yin
