Hmm. Maybe I've thrown gold away then! :-)

Interesting - perhaps he could try it against TCP? That way he'd get a
variety of bots?

It's somewhat amusing to dig into your bot after it makes a decision
you (the author!) don't understand :-)

I (scan) read the Wikipedia article on Elo rankings but didn't feel
that enlightened :-)
It may just be that your bot has been matched against some strong
ones, which has made it lose worse than it should.
Oh - one other comment on strategy (presuming there are lurkers on the
list, just waiting to jump into the fray!) - it's all about growth
rate. If you lose the battle for growth rate, death is only a matter
How you balance growth rate with distance, target planet defences and
competing enemy fleets while defending yourself is an exercise left to
the reader :-)
