A very mixed bag.  According to labels
12 matches with high info gain, maybe 16, plus 3 moves in Zeitnot.
14 non-matches, maybe only 10
It is just possible that 16 of 26 close moves might be significant.
In any event, one cannot conclude a smoking gun here---not near the
degree of the Fritz 10 results for the round-2 game.
