With Gib cuebidding 1st round controls and you having them all. I don't see how you are going to get Gib to cooperate. What you did is reasonable.

What is the problem ? After 2 we have the spade fit(=almost 8 cards) than RKB by E with an all Aces hand and subsequents related answers knowing more about King of diamond suit to get at 6.

Right, no option other than 2D, and I like your 5S bid. I am surprised that GIB did not accept with 14 HCP. You using Blackwood would be useless.

Because you can't find out about the K this way without committing to slam even if Gib has no outside King.

Just bidding slam and hoping is a better option.

No steve2005, i don't think so. East has almost a King that probably is in spade (and with perhaps a lot of Queens .. to have 14 points) and 11 tricks have already to be than considered.

Nonsense! East has great hand but West doesn't know this! West has no idea East has 14 hcp!
Change Q, K, K or K to a lesser card and slam is horrible. West has no was to discover East has these specific cards.
Even J is important and no way to know East has this card.

You have to bid after 2(6/+ cards) because support partner with A6 and also for the four Aces thinking positive to valorize the W hand. Bidding 4NT you'll know that E has K and Q and almost K.

i like 5 bid also. this is hand where west want to know about suit qualities and kings, and east want to know about aces and club losers. human east maybe bid 3 instead 3 then reach slam. with computer 2 bid has limited hand so why it then bid 3 without longer suit it must be computer program. if human partner bid 3 here it would be 7+

Not so. In many 2/1 systemic agreements, including GIB, 2 spades doesn't promise a sixth spade, it just shows a hand unsuited to other bids, it's a "default bid". If you don't have such a default bid, and have 2s promise 6 (which does make some auctions like this particular one easier, so there is a minority of experts who prefer this style), then it makes other auctions harder. You might bid 2nt without regard for outside stoppers and reasonably often reach 3nt with a suit unstopped or from the wrong side. Or bid a high reverse on a very wide range and be in a guessing game whether partner has extra values or not and languish in 3nt when slam is on or bid on past 3nt and find 3nt was the limit.

So if 2s doesn't promise 6, it has to bid a third time to show it explicitly.

Even if 2s promised 6, I don't think that 3 spades should guarantee a 7th, just a suit with good solidity and a preference for spades vs 3nt.

Playing with a good human partner, west can easily discover that East is not worried about his spades and lacks K but does have K and K... west is still in time to stop in 5S, but the slam looks like a fair risk.

Playing with GIB, west could always ask RCKB after 3S and thus discover K, Q, K, stumbling into slam in any case.

Not in a real bridge tournament.
Probably not with GIB either, because it is quite likely to "correct" your slam to a grand or 6NT :D
