The Double Squeeze
I yoosta think a double squeeze would be forever beyond my feeble powers of concentration. I play fast, make my mistakes quick, as they say around here, sometimes altogether too literally. Now, in a double squeeze, you've got three suits to work out. Let's see, clubs'll be the suit they both can protect, while he's protecting hearts and she's protecting diamonds. Or wait a minute. Maybe diamonds should be my central suit while she alone can protect clubs, or should I figure the opposite, that he's protecting clubs and she hearts. Now, how many clubs do I hafta see . . no, wait a minute, it's diamonds I wanna watch the most carefully, and at what trick will the squeeze be effective? Ooof!
And then one day I saw the light, which is that you prepare for a double squeeze in the same manner that you prepare for a single squeeze: you rectify the count (or note that it's been rectified), keep communication between your hands, keep threats to the last possible moment, and voila! If there was a double on the hand, you'll have it.
Oh, it has to have a leetle more complexity than a single. Actually, I'm going to qualify that statement a bit: A double will probably have more complexity than a single. I've given a few elementary squeezes where you don't have to count any suits. You need only watch for one card, and if you don't see it, run the other suit. But there are two-suit squeezes where you have to pay close attention to the cards, visualize the opposition's cards exquisitely well and perhaps take a risk. It may be that this applies to the preponderance of double squeezes also, but I'm going to give one I fell into through no merit of my own after the opponents had rectified the count for me.
So on to some examples.
