It >would have to be at least 3.5. The meaning of 9:3(7 draws is clear to me. It means that there were 19 games and the result was (+9,=7,-3) It means 12.5:6.5 if you calculate the score of the match. This makes no sense at all. And also 9:3 isn't >very conclusive if that really was the score. You need more games. If you played >the same engine against itself you might get 9:3. 9:3 result that is +6,=6 is significant and you can be sure with more than 95% certainty that a result like this is not going to happen when you play the same program against itself. 9:3 result that is +9 -3 is less convincing and in more than 5% of the matches between the same program and itself you will get at least +9 for the winning side if you continue to play until 12 games are won by both sides.
