What is your call, and what would 4♦ mean here?

Copying only so I can allow full description of 3♦ to show.

3♥; West could be something like 3451 and I don't want to lose the potential heart fit. 4♦ should deny a four-card major and deny the ability to go directly to RKC(D). I think this is the auction where WestGIB will always raise 4♦ to 5 and will always raise 5♦ to 6.

No doubt the best call is a splinter bid of 4S. Probably not available with GIB. There is nothing wrong with 4D certainly. It would be nice to see GIB rebid after that call with a few example hands. Probably though with GIB Blackwood is your best bet. I am going to forget about Hearts. If I bid 3H GIB certainly might raise with 3 and it will be tough to get back to Diamonds when it is best.

I think 4♠ is pretty clear if it is defined as splinter. I don't care about heart fit so much when I'm this strong. Otherwise 4♦ ought to be fine.

GIB's continuations after 2c-2d-3m are pretty screwed up. I think it was using 3M bids artificially at one point? I *don't* think 3M should be 4 cards only. I think it's far too important to be able to find 5-3/6-3 major fits, that 3M should show 5+ cards, and it's way too hard to bid these when 3M only shows 4 (partner's going to have 4 cd support incredibly rarely, what do you do after the inevitable 3nt?), and that 5-3 fits are a lot more common than 4-4 in this situation (takes really strong hand to justify 3d on 3451 type shape, many should arguably be opened 1, and a decent chunk of these may have some stiff club honor and justify treating hand as balanced to find major fit).

If GIB wants to find 4-4 fits when opener has 4cd major and longer diamonds, it should use the 2c-2d-3M = 4cd M 5+(usu 6+) diamond treatment.
Over 2c-2d-3c, 3d should be ambiguously defined to look for the potential 4-4 major fits.

I bid 4♦ as I didn't consider 4♠ at the time. GIB passed.

What was the description of 4♦?

Edit: Oh. Probably not right to make a bid that previews as "3-5 total points".

It didn't say 3-5 total points when I previewed it...

Thanks for reporting.

Will be discussed for appropriate solution i guess close to

2♣ - 2♦
2M - 3M where 3M is GF+ values.

Really? Then this is a bigger problem than simply this one auction and should be investigated by the programmers. It should never be the case that a previewed explanation is different than the one posted after the previewed bid is made.
