realized twice. It is surprising that White cannot start with cheks of queen.
In this case black could captures the white queen with spectacular knight
forks in two variations. Bringing White's knight into play, and his active
sacrifice on h4, prevents Black from playing Nf3. The knight also opens a line
for his queen to direction g8 (h9). After 4....Bc6 this piece cannot be
captured. In the thematic try, it is easy to see that the capture would lead
to a stalemate. There is another possibility, but as long as the h3 pawn is on
the board, it is hardly noticeable. It is a harmful piece, this prevents his
queen from checkmate. This will be revealed at the end of the main game.
Therefore white first must get rid of this harmful piece by a passive
sacrifice. At the end of the manoeuvre is good the Qxc6. Black even sacrifices
the knight, and it seems's that, this lead to a stalemate. The surprise: 10.
Kf2!! and then 11.Kg2, and now Black can only avert the mate with Queen
sacrifice. The end is a worthy finish: white can no capture the another queen
of black, but gives a mate instead. Great study.} 1-0

White mates in 7 moves. If he accepts the sacrifice, then black will be in
zugzwang position in several variations on the kingside. In these, Black's
knight is forced to move and white gives mate. The active play on both side,
the zugzwang positions and the two excellent bishop sacrifices are very
valuables. Still, it's the overall effect that really captivates.} 1-0

Themes: Bishops' mutual sacrifices, Positional draw, Reti theme [The study
contains Reti theme if the King's dual-purpose maneuver is combined with
change of false refutations of the thematic tries to achieve each goal
separately. (Problemist of Ukraine >=2 2014)]. In the first phase, both sides
present bishop sacrifices. Black can bring his bishop into play by relying on
the strength of his passed pawns. White uses a well-known but spectacular
motif twice to stop the black pawn , or after the promotion, to captures the
queen. The second phase is strategic. White's king threats the both black
pawns, this positional draw. The play is better after 12.Kb3. It is surprising
how the black king defends against the overpower.} 1-0

first move, White forces the black King to move to unfavorable squares. As a
result, in the main line the black Queen will be pinned. In the additional
line, the black King chooses another square so as not to interfere with his
Queen, but then White changes the plan to another, which was erroneous in the
main line. Complex idea! The bad impression is that White's play in the extra
line is very minimal, White is "offside" in contrast to Black's play on the
try.}) 1/2-1/2

partida la comento Palau en la revista francesa "La Strategie" y fue incluida
en el libro del torneo por M. Lachaga en  lengua francesa; sin duda como
homenaje recordatorio al torneo realizado en Francia. Aqui respetamos esa
decision, y los comentarios por eso estan en el idioma del genial escritor de
ese pais Victor Hugo. Cabe destacar que, muchos anos despues, el mismo Palau,
en su revista Ajedrez, menciona aspectos de esta partida, a la que consideraba
como una de las mejores que jugara en su vida. Y nos dice que el Director del
Torneo, que miraba ese juego, asi se explayo:"...Alejando Alekhine [...] que
estaba observando dicha partida en su momento culminante, y al terminar, con
sus felicitaciones, se puso a analizar la partida y reto a mi adversario por
un alocado ataque que habia organizado con los peones, diciendole que eso era
propio de jugadores de cafe".Observese  que cuando Palau comenta el movimiento
16 de las negras, dice: "Sin duda una jugada debil; pero la posicion de las
negras es ahora inferior y es dificil sugerir una jugada satisfactoria.". Ya
es nuy clara la ventaja blanca, al punto que el argentino se luce mediante una
serie de "Petites combinaisons".} 1-0
