Also we reckoned he would expect 1.e4, which Hiarcs played in its win against Gulko.
So we made 3 or 4 changes to the book ONLY to NEGATIVE some lines: i.e. we left 1.d4 as our ONLY opening move, and in case of 1...d6 we made 2.c4 our ONLY response (so not 2.e4 and he`s walked us into his favourite Pirc!).
We also changed 7.0-0 to a zero in the line that was played - yes, we actually guessed that this *could* be the line he`d go down, as he`s played it so often - we made it that 7.dxe5 ONLY could be played, to avoid the blocked position easily created after 7.0-0. He has admitted that the line we chose is actually his personal favourite, so whether our preparation should therefore be classed as GOOD or BAD, I don`t know. We drew, so we`re content, I think!
The REST of our book was left exactly as it is for the Hiarcs8 release (though with that it WILL be backed up by an extra database from GM games, so that it is a more complete book for customer use and enjoyment).
As you can see from Ted`s file below, Hiarcs came out of book at move 13 and started analysing. Smirin continued playing his moves instantly! If we had arranged for, say, the Fritz7 book or a GM databse book to go in as additional support for our own, we could have stayed in book longer, no doubt continuing to play moves from Smirin`s own repertoire! In fact we, sorry... Hiarcs did play book moves for a while from its own `thinking` but finally varied with Nd2, a move which Smirin himself said was new to him and which he thought was very interesting.
I hope that`s of interest!....
