Given that 6N is quite good despite that North is min, I probably should have bid 6N rather than 4N.

While I am grateful to North for rescuing me, should it have done so?

I would pass with the North hand. I wouldn't call this a good slam. East gave away the spade position at trick 1. On a club lead, you have a lot of work to do.

GIB should certainly be programmed not to accept a quantitative invite when he has 15HCP and 15total, if his previously-stated range is 15-17HCP and 15-18total.

In principle it's perfectly fine that GIB relies on simulations instead of walrus rules when it has captainship. But sometimes the sample size is too small. A Bayesian approach would be great - formulate a prior distribution for the the number of tricks that can be taken and then update that prior using the sims. I suppose this is sci-fi for the time being.

Thanks for reporting.

Fixed ( by not allowing to be slippery in judgement of HCP's amount when is being invited ) in v31.

Of course fix applies for all quant 4NT ( 2NT opening, 2♣, etc sequences ).
