loaded 71 hackers
testing: s.matches_are_sane? = true
getting new hackers
 hacker1 will probably defeat hacker2
picking hacker1
@sequence = "L" (1)
i know about 1412 hacker matches
guessing accuracy ==   0.00%
checking on last guess and getting new hackers
last guess was good

# first, run protocol.rb for a little while to get some match data into gamelog
$ ruby protocol.rb
...later...
# then, run smart.rb (reads gamelog and plays games with the server until it wins)
$ ruby smart.rb
