Westerly Written by Guest on 2005-09-29 09:18:37 I am new to notation, so this may sound a bit awkward. (Assuming no impasse, i.e. as long as each pawn does not move one space straight ahead) Scenario A. 1.White g4-g5 If Black e6xg5 then 2. White h4-h5 If Black moves front pawn (either g5-g4 or g5xf4) then 3. White h5xg6 and can then proceed unchallenged in g file. If Black moves back pawn g6xh5 then 3. White f4-f5 and can continue in f file unchallenged. Scenario B. 1.White g4-g5 If Black h6xg5 then 2. White f4-f5 If Black moves front pawn (either g5-g4 or g5xh4) then 3. White f5xg6 and can then proceed unchallenged in g file If Black moves back pawn g6xf5 then 3. White h4-h5 and can continue in h file unchallenged. Comments: White moves the middle pawn first. Wherever Black moves next, White advances the opposite file. (If Black moves in h file, White moves in f file, or vice-versa) If Black then moves his front pawn (either straight ahead or capturing a White back pawn), White can capture Black's back pawn and advance. If Black moves his back pawn to capture White's 2nd advance, then White can continue with his back pawn, unchallenged. Either way, White should promote first.
