lenny (black) v. computer (white)

in this 19-move knockout, lenny (playing black) develops his pieces methodically (yet quickly), owns the center, pins white’s king knight, and eventually sacrifices his own bishop enroute to a crushing mate. .white doesn’t necessarily blunder, but lacks creativity and enthusiasm with his development, leading to a cramped and weak position.

lenny telegraphs his bishop-sacrifice (which the computer ignores), and white pays the heavy price – not only with his queen but also with a devastating, lightning-quick mate.


black/lenny uses his textbook style (secure the center; develop openly; combine forces), giving his pieces plenty of freedom and options. .he castles into safety on his 10th move, but more as an insurance maneuver than anything else.

given the opportunity to sacrifice his king-bishop, lenny proceeds to crush the computer’s pinned and cramped existence, showing mercy only by expediting white’s eventual demise.
