I think 2d and 3nt should deny 5 spades; will this keep GIB from pulling 3nt to 4s?

In general I think GIB supports 2nd suits on 3 too often, like on auctions 1c-1s-2c-2h-3h; this shows only 3 hearts but I think it should have 4 normally. Supporting later can be on 3. It can bid Moysians based on sim, but it better be giving partner 4 cds in the suit not 5 when it sims.

It should have been book bids right through- simple slack bidding programming.

There is some crossing of rules between NMF and 4SF, which causes that inappropriate explanation.

Will be set for fix.

Everything is simple, is it not?

Its not simple- its hard work- something that was an anethma to Ginsberg and every other bridge computer programmer- They should have been using heuristics (metarules) as other expert systems not ludicrous long chained simulations.
