Chess Tiger won 67.65%.
The strength difference that can be computed from your match is approximately
124 elo. The margin of error for 80% confidence is approx. 8.5%, so your match
is significant and it is possible to say with 80% confidence that Tiger 13 is
between 64 and 183 elo stronger than Crafty 17.14 under the conditions used in
your test.
