Book question

Post by xr_a_y » Mon Mar 30, 2020 3:05 pm

For testing, I often use the Adam-Hair-12moves-397457.pgn file.

This Minic win versus Ethereal was unexpected so I looked at it deeper.
It seems both engine agree that the position is quite highly in favor of white here. SF even scores it +2.5 !

Of course, if many games are played and/or I let both side play this as white, this will be fine.
But I wonder if this last a5 move shall really be "in book" ?

Any recommendation for another a long book file by the way ?
