# Find deals where south is "AK K52 98765 962" and north has a gambling
# 3nt hand.
#
# This was one of the first examples I gave of how "smart stacking" could
# be used.
#
# Compare output from this with output from ex/3nt-nostack.tcl to make
# sure that the relative odds are being obeyed, eg:
#
#   deal -i ex/3nt-stack.tcl 1000 | sort | uniq -c | sort -nr > stack.txt
#   deal -i ex/3nt-nostack.tcl 1000 | sort | uniq -c | sort -nr > nostack.txt
#
# Obviously, they shouldn't be exactly the same, but they should be similar.
