If you use the most likely estimate
The probability for 10:0 is smaller than (23.5/31)^10 because there are draws.

The result was +20, =7.-4 so if you use the most likely estimate you get
probability (20/31) for Junior to win
7/31 for a draw and 4/31 for a loss

(20/31)^10=0.012493... so the probability is less than 2%

I ignored the fact that the white probability is different from the black
probability but not ignoring it does not change much the result because you get:

(10/15)^5*(10/16)^5 that is 0.012558...

If you do not ignore the last 10 games and ignore the colours you get
(30/41)^10=0.043992...
