I've only just started playing with (dumb) bots so maybe mine wasn't the wisest bid, but I find it hard to believe this sequence is worthy of a jump to 7♥?

GIB jumps to 7 just because it believes got enough points by partner and its hand. Maybe 7 is too much, but according to points 6 is the minimum it could bid without the need of blackwood.

The sum of points shown by all hands seems like real only at theory, as the minimum of East-12TP West-9TP South-31TP and North sees 11TP, but North has to rely on partner's bids. As maximum i can recall the max TP sum looks like 76 ( min 64 shown here ).

31TP seems like high requirement, so that could be softened a bit, but understandably can't be weak distributional hand, as partner 2♥ is not engaging bid, just picks one of your promised suits.

Also by bidding 4♦ ( after shown at least 4-4♥ ) that adds additional points ( 4♥ will be just 12TP ) to your expected hand. No need to pick choice of 4♥ or 5♦ as 1) level is higher and 2) you already know you have fit in hearts.

2♥ seems a bit undervalued bid. It worth bidding 3♥ instead with and singleton spade and almost second fit in second shown suit by partner.
3♥ promises 4+♥ and 10-12TP, which GIB has, so it will be investigated as appropriate call here.

Thanks for the explanation, georgi.

The reason 4♦ shows so much is that it's a slam try. If you have enough to invite slam opposite North's possible 0 HCP, you have to have a real monster.

If we fix the robot to bid 3♥ with the North hand, then 4♦ wouldn't show so much. Then North would have a minimum for his original response, and wouldn't overbid.

Bidding is all a bit weird really. North is too strong for 2H, East should just bid 4S and West should double 7H!

I would expect a lot more points in South (16+ regular HCPs - I don't deal with "total points") for the 4D bid, given pass and 4H are available. Perhaps some would prefer to use that as a fit-non-jump though.

Even if 4♦ is standalone suit not related with hearts, it comes unforced and after double, so it must be still at least 18HCP, which makes Pass not an option for North.

North could then cuebid in spades showing fit in the solid diamond suit by South.
