An entertaining game from P. H. Clarke, 100 Soviet Chess Miniatures (1963) offers a lesson in vulnerability. White’s king appears more exposed, but Black’s king is in mortal danger on its starting square.
Black to move
The game is Barshauskas — Chesnauskas, Championship of Lithuania 1955. Black’s problems stem from the greater mobility and coordination of White’s forces. As Clarke notes, “It is worth remarking that while the position of the Black king in the centre is of the utmost import, the comparatively exposed state (i.e. to the normal castled position) of the White monarch is of lesser significance. The reason lies, of course, in White’s lead in development” (31).
