Karpova: Jacques Mieses' annotations (pages 178-179 of 1949’s June issue of the 'BCM'):5.c4 <In my opinion not the strongest way of treating this variation.>
6.Bg5 <This loses a pawn. White should have first played 6 Nxc6.>
10.O-O <It is a very well-known matter of experience that losing a pawn in the opening by a mistake is often the involuntary equivalent of playing a quite promising “gambit”. Thus, here, White, with a pawn down, has undoubtedly got a compensating advantage in development.>
13.g3 <This is a grave positional mistake weakening the king’s side.>
16...h5 <Promptly taking advantage of his obvious attacking chances.>
17.Nd2 <Even after 17 h4 White’s position would soon become untenable.>
20. White resigns. <White resigned the hopeless game. When I announced the result of the game I caused much hilarity by adding the joking remark: “Die ‘Jugend’ hat gesiegt.” (“‘Youth’ has triumphed.”)>
