iandayre Posted February 12, 2015 Report Share Posted February 12, 2015 Now this one we have all seen before. Can't GIB have some criteria for high level doubles other than high card point count? Quote Link to comment Share on other sites More sharing options...
georgi Posted February 13, 2015 Report Share Posted February 13, 2015 Improved, so GIB won't use such last chance doubles once there is huge fit existing. So if it leans on double, will be in clear missing fit and points. Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted February 13, 2015 Report Share Posted February 13, 2015 What strikes me as a bit odd is that only needs to run a few sims, to tell it that it should be bidding 5H over 4S (or at the very least not doubling 4S). How can you "improve" on running the sims? Quote Link to comment Share on other sites More sharing options...
Stephen Tu Posted February 13, 2015 Report Share Posted February 13, 2015 I think the rules database is such that sims are only run on some actions, not all, so perhaps it wasn't simulating the effect of 5H before and just doing a stupid double based on point count action.

georgi Posted February 13, 2015 Report Share Posted February 13, 2015 When GIB searches for calls and it finds an appropriate call where all constraints are ok, it doesn't need to simulate ( still based on call properties, could sim by force if there is some ambiguity ). However, based also on priorities there are some safe-belts which should protect GIB to throw a pass or select emergency call once there is a risk to make the opposite. So here what GIB found was inappropriate double based on just values ignoring possible fit. In old version West GIB gave automatically double ( simming doesn't help as the double rule was accurate ). Now in next, GIB will evaluate this lower level double additionally, and respectively having such hand like here will not use it. Instead will now consider pass / 5♥. Old version 5♥ wasn't found at all, now 5♥ is found in almost all cases for advanced-GIB. Quote Link to comment Share on other sites More sharing options...
