They are a problem... because Deep Sjeng played much more book moves
in this game than Fruit? Didn't you say both used the same book?
Playing 75% longer in book in a 4+1 blitz game is quite a lot ;)
Seems you forgot to disable a second book for Deep Sjeng.
(Fritz 8 would have made the same blunder in a blitz game)
