A bishop so developed is characteristic of the Italian Game, 1.e4 e5 2.Nf3 Nc6 3.Bc4 (particularly the Giuoco Piano, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5, where both players have Italian bishops), and stands in contrast to the "Spanish" bishop on b5 characteristic of the Ruy Lopez.

In round ten, the position on the right arose after a Giuoco Piano: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Nc3 d5 8.exd5 Nxd5 9.0-0 Be6 10.Bg5 Be7 11.Bxd5!
His name is attached to the Moeller Attack in the Giuoco Piano (1.e4 e5 2.Nf3 Nc6 3. Bc4 Bc5 4.c3 Nf6 5.d4 ed4 6.cd4 Bb4+ 7.Nc3 Nxe4 8.O–O Bxc3 9.d5) and the Moeller Defense in the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3. Bb5 a6 4.Ba4 Nf6 5.O–O Bc5).
Chigorin has several chess openings or variations of openings named after him, the two most important being the Chigorin Variation of the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 d6 8.c3 O-O 9.h3 Na5 10.Bc2 c5 11.d4 Qc7) and the Chigorin Defence to the Queen's Gambit (1.d4 d5 2.c4 Nc6).
Black's most common reply is 2...Nc6, which usually leads to the Ruy Lopez (3.Bb5), Italian Game (3.Bc4), or Scotch Game (3.d4), though 3.Nc3 Nf6 (the Four Knights Game), often played in the late 19th to early 20th century, or, less commonly, 3....g6, (the Three Knights Game), are other possibilities.
In contrast to the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5), by delaying Nf3, White leaves the f-pawn free to move and retains the possibility of playing f2–f4.
Steinitz Defense Doubly Deferred to the Ruy Lopez: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 d6 (also called the Russian Defence)
