On the point of throwing in my cards but made 100% on the lead :rolleyes:

I appreciate as smerriman has pointed out the Bot does not know how to explore for slams in certain cases

GIB's cuebidding is broken -as you can see your bid promised 25+ total points. GIB adds up the points and concludes you can't be missing any important cards, so has no need for Blackwood. If you really had 25+ total points, 7 would have made.

You weren't going to find out anything useful over 4 anyway, so just bid 4NT over 4 and you're sorted. (Of course, 6 goes down, but it's the contract you want to be in.)

I appreciate the cue-bidding, point ranges and control checking are broken in certain circumstances
Unfortunately I cannot remember the circumstances during play so rely on pure luck
I imagine some look at my 100% and suspect something dodgy at times
I was perilously close to not looking closely and throwing the hand in for a 0%

Apparently defensive leads also need some work - although I haven't checked why it picked a diamond to my Ace
But maybe the West bot has the same assumption of us having all Aces as the North bot
It really assumes South has that many hcps

EDIT I did run a Sim and it has approximately 1% chance of defeating the slam on any lead other than a diamond, although maybe my constraints were a bit looser than 25 hcps for South. Small chance of an Ace with East
