>>>>>>[on AK/Jxx/AKxx/KQT9 after RHO's 1H at RED (unfavorable colours)]

I also simulated this.  My assumptions were that opener's partner would
stretch to respond with spades, but wouldn't bid on a 5134 2-count
or the like, and that partner would stretch to balance but would 
pass with a random 2-count or a balanced 7-count (no shortness).

This one really surprised me.  Double (with an intended 1NT rebid over
1S, or raise partner's minor to 3, or double a 2H rebid by opener)
was a clear winner, both pass and 1NT trailing.  Pass
leads to defending 1H much too often, and when partner can reopen
it's difficult to get intelligent cooperation when he must be
subminimum.  1NT was almost always inferior to double, but getting
in the auction was usually a good thing.  Partner never had the 
values to raise to 3NT, and at 1NT it doesn't always matter if they
run 5 hearts if we take the rest.

Double worked very well, expressing values properly to get to game
or slam when they exists, and much more flexible than 1NT for choice
of partscores.  The dreaded 3NT off the first 5-6 hearts never came up.

Judge for yourself, here are the hands... I commented 26 of them
but there are more at the end.  The text may not show up properly,
but if so saving to a file and cat'ing it should work.  Should be
able to strip those ^M's...)

Double seems to have a slight edge since you can
tell partner you have 20 (!!) points immediately,
and he will cooperate with slam tries.  Pass could
work but partner, having stretched to balance, may
be reluctant.  1NT is probably hopeless.
