Help
OK, so probably I am supposed to bid 4♣ instead of 4♥ or something like that, but regardless:
- why does 3♥ show only 3+H? I think it should nominally show 4 hearts. If GIB judges to bid it on 3, whatever, but I think that's rare as I think 3343/2344 hands can gamble a pass or bid 3nt based on sim.
- I think 4h should have an upper limit that prevents North from trying for slam, I think it should show 4 hearts not 5+, and after raising hearts it shouldn't promise spades anymore (maybe south has hearts and diamonds, if north had supported spades south was planning on a diamond retreat).
for sim purposes I think initial double should be treated as 4h, 4s, 10+ hcp (not 4+H, 4+s), but then on different auction continuations it has to be adjusted as south bids nt/supports diamonds etc.
I also think GIB should perhaps be opening 1h on these minimal HCP 5-6 hands with the Kings being stiff instead of inside the long suits.
