I'll consider it.


I found it on the Internet:

Lasker doesn't seem to know this line, because he says on
the Giuoco Piano "The steady development with ... 6. B-KKt5, B-K3
or Castles tends to a draw from the very first" (game #4), implying
that
castling is an acceptable move here - I am not, of course, claiming
Lasker would overlook the problem with it, just that he does not
discuss them here.

The first 5 moves are the symmetrical Giuoco Pianissimo. Then 6 B-KN5
O-O? 7 N-Q5 B-K3? - black should have done P-KR3, driving back the
bishop. Other 7th moves are no better, in particular B-KN5 is met by
white's P-KR3 later, moving the bishop back and giving the same
situation. Now the mate goes 8 NxN ch PxN 9 B-KR6 KR-K 10 N-KR4
anything 11 Q-KB3 anything 12 Q-KN3 ch K-KR (forced) 13 Q-KN7 mate.
Or, alternately, if black had played BxB, 13 B-KN7 ch K-KN (forced) 14
N-KB5 anything 15 N-KR6 mate is perhaps more elegant in giving mate
with a knight. Black can avoid this mate only by sacrificing his queen
(several ways).

Black's best move is probably 6 ... P-KR3, the Ruy Lopez defence, to
forestall the whole chain.

Is my analysis correct? Is there any way for black to avoid the
ultimate mate, without losing his queen, after the 7th move here?

Could you please fill in the missing moves. I do not know what you
mean by "The first 5 moves are the symmetrical Giuoco Pianissimo"?
