Be6 9. Nbd2 Nc5 10. c3 d4 {A small surprise. Black chooses what was at one
time the most principled variation of the October Variation of the Spanish. Of
course, I knew that Victor Mikhalevski is rightly considered one of the
greatest specialists of the October Variation, but, frankly speaking, I did
not think for one moment that my opponent would choose this well-developed
system. This move offers a wide range of ways to simplify the position, where
White will in the process retain the better, albeit only slightly better,
position, whilst Black will have no chances to confuse matters. And since, in
my preparations, I had noted above all my opponent's tactical mastery in
complicated positions as being the strongest aspect of his play, such an
opening approach suited me fully.} 11. Bxe6 ({The alternative is the

arrangement of his pieces, since now he must permnanently concern himself with
the defence of the pawn b2.} ({In all previous games, Black chose a different

are Rhe1, Nf5, Bf4, attacking the pawn on d6. It is also possible to transfer
the rook along the third rank, attacking the weakness on a6. The whole
