which is heavily analysed and leads to no advantage for White. So I chose a
less analysed alternative, though Black has several ways of equalising against
it. que ha sido enormemente analizada y conduce a posiciones sin ventaja para
las blancas. Por eso elegí una alternativa menos analizada, aunque las negras
tenbgan distintos caminos para igualar frente a ella.}) 8... Bd6 {Unusual but

14. f4 Ndc5 {Black could have exchanged on c3 and then c4, but then it is
difficult for him to mobilise the Q-side pawn majority, while White has
attacking chances. Las negras pudieron cambiar en c3 y luego efectuar c4, pero
en ese caso es difícilpara ellas movilizar la mayoría de P del flanco Q,
mientras las blancas conservan chances de ataque.} 15. Nxe4 Nxe4 16. Bxe4 dxe4
{Now the e-file is nearly full!  I have a slight preference for White's
position, as my bishop is slightly less blocked in than Black's. It can come
out via h4. Also the f4-pawn gives White some attacking potential. However,
Black can counter on the queenside and try to gain control of the d3-square,
so I would hesitate to claim any advantage. Ahora la línea e está casi llena!
Tengo una pequeña preferencia por la posición de las blancas, ya que mi B está
levemente menos bloqueado que el de las negras. Puede jugar vía h4. También el
Pf4 extra tiene algún potencial de ataque. De todos modos, las negras pueden
contar con el flanco dama, y tratar de ganar el control de la casilla d3, de
modo que no hesitaría en reclamar alguna ventaja.} 17. Qg4 Qc5 18. Rd4 Rad8 $4

able to analyse this position before playing 19 b4. I always analyse the
position resulting from a forcing sequence before playing the first move of it,
as just occasionally I change my mind and look for earlier alternatives.  At
first sight it looks as if White's three extra pawns should guarantee an easy
win. But with opposite coloured bishops and queens still on the board, the
number of pawns is often less relevant than the relative safety of the kings.
Here the black king has found a safe haven, while the black queen and bishop
are bearing down the long diagonal towards the white king.   White's queen and
bishop are temporarily of little use for defensive purposes, so I had to look
closely at 28...Qa4 here, getting in behind the pawns.  Rittner tries a tricky
alternative. Webb: #  Since all Black's moves were forced I was able to

alternative. Como todas las jugadas negras fueron forzadas, pude analizar esta
posición antes de jugar 19.b4. Siempre analizo la posición resultante de una
variante forzada, aunque ocasilnamente cambio mi forma de pensar y miro
alternativas anteriores. A primera vista luce como si los tres P extra de las
blancas les garantizan una fácil victoria. Pero con B de distinto color en el
tablero, la cantidad de P es a menudo menos relevante que la seguridad
relativa de los K. Aquí el K negro ha encontrado un paraíso seguro, en tanto
la Q y B negros están apuntando sobre el K blanco por la diagonal larga.   La
Q y B blancos tienen momentaneamente alguna utilidad para propósitos
defensivos, de manera que tuve que considerar mucho aquí  28...Qa4, penetrando
entre los P. Rittner intentaba una alternativa tramposa.} e3 (28... Qa4 {I
