Zettel has kibitzed 2 times to chessgames

Dec-08-05 H Camilleri vs Uhlmann, 1969    Zettel: The d-pawn falls if White blocks the D file...hence, Kf1.      Oct-05-05 Benoni, Four Pawns Attack, Main line (A69)    Zettel: One can arrive at this position from a King's Indian where one has re-captured on d5 with the c-pawn and not the e-pawn as is being done today.
