October 6th Master Lecture at KCC

diagram Zhenevsky-Lasker, Moscow 1925
Black to play after 24.Qe3?


On Thursday, October 6th from 8:00 p.m. to 11:00 p.m., life master Scott Massey will lecture at the Kenilworth Chess Club. His topic will be "Moscow 1925 and the Beginnings of Soviet Chess Hegemony." The lecture will cost $5 and will likely start at 8:15 p.m.

I have posted games from the Moscow tournament (Torre-Saemisch, Capablanca-Zhenevsky and Torre-Lasker) in anticipation of that talk. I thought I'd add another, and one Scott may discuss: Zhenevsky-Lasker. The game was memorable mostly for the way Lasker demonstrated the relative equality of Rook+Bishop+Pawn vs. Queen in the middlegame, depending upon the position. Lasker's play is reminiscent of modern players who do not hesitate to sacrifice the Exchange or to accept material imbalances involving the Queen where the position allows it.

As usual, you can play over the game online, download the PGN, or get the PGN as text below.

Surely very few chessmasters would have offered the Queen at move 13 let alone survived doing so.} 0-1
