This isn't even close to 6S in my view. What would you bid with AQxxxx Axxx x xx over 4D? It's a clear 4S in my view. Even if you don't accept that, there are millions of slightly stronger hands where everybody would bid 4S and you need some luck to make 5S opposite Mike's example hand - say AQxxxx Axx x Kxx.
I would not overcall with a minimum opening hand and a patchy suit, especially red v white over a 1st seat 4D, so I have no trouble passing with AQxxxx Axxx x xx. I understand bidding, but (and I recognize that many fine players would), it isn't my style. It isn't just that double on my left spells 800-1100 against a partscore or NV game, since one cannot live in fear at the bridge table. However, one has a partner, and my preference is to have a my hand be stronger the higher I need to overcall. For example, AQxxxx x Axxx xx is a minimum but 'do it every day' 2S call over a 2H opening, but is below expectations for a 3S overcall of 3H...although I would probably do it, especially if you gave me the 10 of spades.
And, yes, I would always bid with the AQxxxx Axx x Kxx hand, but would see that as close to the worst hand I could have for the action.
Given that, my example for advancer to bid 6S was a little weak, but not by much. You can't have it both ways, when the opps put you under pressure. You should not aim to avoid bad small slams yet be aggressive when bidding grand slams...it should be the other way around, simply based on arithmetic. A small slam, assuming the opps swing the other way and stay at the 5 level, need be no better than a 50-50 proposition, plus a small amount for the opps taking a phantom. The grand has to be heavily odds-on.
So one reason I would pass some hands on which Arend would bid 4S is that I want my partner to err on the aggressive side in advancing my overcall, and the weaker the overcall may be, the less he can be aggressive. Note that if advancer merely bids 5S, East will very rarely be able to bid 6 even when it is strongly favoured, if one knew advancer's hand, to be a good contract.
