Tiger has a simple (and probably naive) book learning system. It works
acceptably well when the book provides enough alternatives, but Junior 6 has
found a line with too few variants and managed to repeat the same line (or
almost the same) 12 times in the 40 games match against Chess Tiger 12.0 DOS.

Probably because
1) its book is wide enough that by just picking random lines the probability to
repeat a lost game is small.
2) CM6K has a very strong engine, no doubt.

I think Bertil Eklund has the games. I don't have them.
