The other day, I reserved the magic 21J on some TATL (I've got 3 MRs coming up, so I can't remember which ) but then panicked at the last moment and changed to 17B because I've had the ol' EQ swap ending up in plain ol' 21J. Swaps don't affect 17AB. So 2 questions:

1. How many times have you had magic 21 swapped out from under you?
2. Do you play it conservatively and book 17AB instead of 21HJ?

p.s., I don't know why I called it magic - I'm a bit under the weather from whatever got passed around at Lucky's leather DO last weekend.
