What tricks does declarer have? Two diamonds, for sure. At least seven hearts, I suspect. He must have the ace of clubs or he is toast no matter what I do. That's ten, and if he has ♦Kxx, he's up to twelve already. So instead give him, say, x AKJxxxx xx AKx. Now he has eleven tricks, and we are club-spade squeezable unless we break it up somehow; and with two entries in each minor suit I don't think it's possible. But adjust his hand to x AKJxxxx x AKxx, far-fetched though it seems, and we can break up the squeeze by playing diamonds to destroy his late entry to dummy. However, if we overtake to shift to a diamond, we are just setting up his ruffing finesse in spades! Instead we need to leave partner on lead and hope he can work it out, perhaps playing the nine of spades trick one to suggest diamonds.
Anyway, there seem to be a lot of variations, and I'm sure some of then require us to overtake and switch to something, but it seems to me like we're just setting up an extra trick in spades for him most of the time, and that may be number twelve.
