1.P-QB4(c4) is a relatively modern
flank opening that first became popular after its
use six times in an 1843 match by top English player Howard
Staunton against top French player Pierre Saint-Amant. |

White avoids early centre occupation and often
fianchettoes his KB, putting
pressure on the Q-side pawns and attacking along the QB-file
(move 11, right) once Black plays
P-Q4. White is thus often playing the
Sicilian Defence with a move in hand, but
Black has several good lines. |
| One advantage for White is the difficulty of
transposing the defence into some other opening, although
several initial transpositions into Queen's
Gambit and QP openings are possible. Immediate variations include the
Symmetrical,
King's Indian (to
Closed),
Hedgehog,
Anglo-Dutch and
English Orang-Utan. |
