GIB has never been very good in double followed by new suit auctions. Yes I know my double is rather dubious, probably I should just bid 1♥ but that doesn't affect what North should do:

---

- think 1♦ should also deny a 4 cd major, so 3- ♠, 3- ♥
- I think 1♥ should cancel the promise of 3+♦, 3+♠, and just show 5+ H, and maybe 16+ total points (a bit lighter in balancing seat than in direct?)
- North should certainly raise hearts with 3 hearts. I'd say 2♥ should be something like 5-7, 3♥ 8-9?
- don't particularly think it should be bidding 2♣ to play opposite a supposed takeout double of clubs which is supposed to be short clubs. It should be allowed to bid 1nt rather freely with a smattering of points and 2- H.

I think your double followed by a suit is correct. In both SAYC and 2/1 that shows extra points, and you could have as little as 10 HCP for your initial double. And your heart bid promises a five-card suit. This has been standard bidding for as long as I've been playing. The robot absolutely should be able to judge this situation and correct to 3 hearts.
