is rather weak, it was much more promising to keep the queens on the board and
to go for a deadly attack with 17.Qf2. Bestia 0.90 has surely calculated that
it can also win black's centre pawn and may for this reason have preferred the
exchange of queens. It was hard to already see here that black will entry on
the first rank with his rook when white's pieces like the bishop c1 and the
rook a1 are rather paralyzed.} 17... dxe4 18. Nd2 Bb7 19. Nxe4 {(?) As the ot

better perspectives in view of the half-open c- and f-files. Or in other words:
it is much easier for Black to find a plan.} 11... Rc8 {

rook maneourvre. One would rather expect 14.Rad1 to put pressure on the only
weak point in Black's position.} 14... Rf8 {And this time a somewhat mystery
move on the part of Ufim302. I see no reason for retreating the f6-rook to the
last rank. Black has two options: a) to play on the queens wing with 14...a6
later to be followed by b7-b5, Nc6-a5-c4 or b) to seek some attacking chances
on the kings wing with 14...Qe8 and the idea to bring the queen to g6 or h5
followed - depending on the circumstances - by g7-g5. There are of course
other moves like 14...Qb6 but the ideas demonstrated in a) and b) are the ones
that follow a positional sound plan.} 15. Qb5 {Not a good idea and only losing

please have a look at black's second rook at f8. It was of course the other

defence of c6 or to put some pressure against white's b2-pawn with Rb8. There

understand such positions. The normal way of things is that programs hesitate

It must be emphasized that Black has not at all a bad position. But that's not
the point. Chess programs are quite often unable to find the best plan in

programs to choose lines that lead to such situations.} 17... a5 {17...Qc6!}
