Fantunes is not GCC Compliant because it uses Transfer Responses to it's opening 1C bid, and also it fits 4441 hands into the 1NT bid. I'd imagine a GCC Compliant Fantunes system would move 4441 Bids to 1D and 1C, and either change the 1C bid to 15+, or simply remove the transfer responses. I'm interested in the system and I'd be interested if we (the forum) had an effort to try to convert Fantunes to GCC

I don't want to start a new thread or anything for this, but are there any programs out there that calculate how often a bid is made? Mainly I'm interested in figuring out opening frequencies / mean opening rates (see here http://bridgewithdan.com/systems/bridge-system-collection.txt) for a couple of systems / conventions / conventional responses.

3♠ is probably a sign off, you've shown enough points to force to game if you are looking at the hand from the GIB perspective, so the cue bid is forcing showing a good hand. When East raised to four, GIB was looking for a nice juicy penalty double opposite a good hand (after all, the bot has 3 tricks).
