Black's Bayou French Two-Step
Tarrasch Main 5.Bd3 · sung from Black's side
Verse 1
Pawn to e6, then pawn to d5 1.e4 e6 2.d4 d5
Knight to f6, he pushes e5 3.Nd2 Nf6 4.e5
Knight back to d7, pawn to c5 4...Nfd7 5.Bd3 c5
His pawn chain rests on d4, mon cher
I chop at its root, c'est la guerre
Chorus
Knight to c6, I take on d4 6.c3 Nc6 7.Ne2 cxd4
Pawn to f6, my knight takes back 8.cxd4 f6 9.exf6 Nxf6
His d-pawn stands alone, no friends no more
Down my half-open f-file, allons, attack
Verse 2
Bishop to d6, my queen to c7 10.O-O Bd6 11.Nf3 Qc7
Castles short, then knight to h5 12.Bg5 O-O 13.Bh4 Nh5
His lonely d-pawn, that's my prize
Two knights still guard it, don't snatch it blind
Mind my e-pawn, keep e6 behind
Then my e-pawn breaks to e5 in time
Chorus
Knight to c6, I take on d4 6.c3 Nc6 7.Ne2 cxd4
Pawn to f6, my knight takes back 8.cxd4 f6 9.exf6 Nxf6
His d-pawn stands alone, no friends no more
Down my half-open f-file, allons, attack
The whole song hangs on one picture: after ...c5, ...cxd4 and ...f6 White is left with an isolated d-pawn in nearly three quarters of master games here, and Black's play — bishop d6, queen c7, knight h5, the e-pawn's e5 break — is about pressing that pawn down the half-open f-file without grabbing it while two knights still guard it.
