1. e3 ... ;A00 Van't Kruijs Opening. Not very
;aggressive for a first move, but play
;may transpose to lines of the English
;(c2-c4), Queen's Pawn openings
;(d2-d4),or reversed French (delayed
;d2-d4) or Dutch (f2-f4) positions.
... e5 ;A00 Van't Kruijs Opening. 1.e3 is a
;reasonable, flexible move. 1...e5 is an
;aggressive response, requiring White to
;now declare his space intentions. At
;this point, 2.c4 creates a quiet form of
;the English Opening; 2.d4 exd4 3.exd4 d5
;transposes to the Exchange variation of
;the French Defense. 2.b3 is an
;interesting idea. Other second moves by
;White are less practical.
2. Nf3 ... ;Out of Opening Book. c4 would have been
