I do not agree with the comment "After 14. Qxe4 White gains
only two pawns for the piece. On the other hand, Black is
reduced to a grom defensivve job, which would not suited
Lasker at all." We all know that Lasker was one of the best
defender in chess of all times. In my opinion, the sacrifice
14.De4 is indeed a very strong move giving White a decisive
advantage. Anyway for CM9_T05 it's the best move after a
long thinking time.

Now 15...g5 was claimed to be stronger than Laserk's 15...g6
but I doubt that this move could save the game. See also
the analysis of CM9_T05.
