The auction with opps silent: 2C, 2D, 2S, 3S, 4C, 4NT, 5S (all 5 plus the Q), 5NT, 6S (no side K's) - 7S?? Probably I don't understand simulations well but I can't imagine why it would think a grand slam was good missing both minor Kings.

Gib doesn't understand the concept of Captaincy, the big hand will normally be much better off making the decision between grand slam and small slam. Getting an answer of 5 KC plus Q trump is ridiculous. The exception to the rule is if the weaker hand has a source of tricks.

Agreed, but that's a different problem, Steve... When the weak hand takes control, you're more likely to fail to get as high as you should be, because the weaker hand doesn't what all the necessary information (about the stronger hand's trick-taking ability). In this case, the hand in charge had all the information and just did something dumb and bid to a level that it should have known was too high.

Gib should cuebid 4♥ to show K not take over and bidding 4N. But Gib doesn't cuebid Kings another flaw!
