--- Fit-Jumps after 1M - (X)
Partner opens 1H or 1S, your right-hand opponent makes a takeout double, and you
have a fit for partner plus a good second suit. A jump shift in a new suit is a
FIT-SHOWING JUMP, showing in one bid:
. 4+ card support for partner's major
. a 5-card side suit with at least one top-3 honor (a real source of tricks)
. limit-raise-or-better values (about 10-12 support points)

Auctions (north opens 1M, east doubles for takeout):
. 1H - (X) - 2S / 3C / 3D — fit jump: 4+ hearts + a good 5-card spades / clubs / diamonds
. 1S - (X) - 3C / 3D / 3H — fit jump: 4+ spades + a good 5-card clubs / diamonds / hearts

Why jump instead of redouble or a simple raise? The double crowds the auction, so
one descriptive bid is worth a lot. Showing the fit AND where your side values live
lets opener judge the double fit, spot wasted honors, and decide how high to compete
or whether to bid game/slam.

Opener then evaluates:
. fitting honors opposite your side suit -> push to game or slam
. wasted honors opposite your side suit -> compete only, or stop in the major
. minimum with no side fit -> sign off in the trump suit

# Competitive Fit-Showing Jump: partner opens 1M, RHO doubles, you fit-jump.
# North opens 1H or 1S. East makes a takeout double. South (an unpassed
# responder) jumps in a 5-card side suit, promising 4+ support and limit+ values.

####### What we WANT #######
# 1. North opens 1H or 1S.
# 2. East makes a takeout double (short in the major, opening values, support
#    for the other three suits, no 5-card suit of its own to overcall instead).
# 3. South has 4+ card support for partner's major.
# 4. South has a 5-card side suit with a top-3 honor.
# 5. South holds limit-raise-or-better values.

# 1. Wanted opening: north opens a major
nOpensMajor = oneHeart or oneSpade

# 2. Wanted takeout double by East: short in the opened major, 3+ in every other
#    suit, no 5-card suit (so BBA doubles rather than overcalls), opening values.
