Sometimes the opening is named after the pieces. The King’s Gambit (1.e4 e5 2.f4), the Queen’s Gambit (1.d4 d5 2.c4), the Two Knights Defence (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6), the Three Knights Defence (1.e4 e5 2.Nf3 Nc6 3.Nc3 g6), the Four Knights Opening (1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6), the Bishop Opening (1.e4 e5 2.Bc4), and the Bishop Gambit (1.e4 e5 2.f4 exf4 3.Bc4).
Pawns are featured in the Two Knights Variation of the Caro-Kann (1.e4 c6 2.Nc3 d5 3.Nf3), the Three Pawns Gambit (1.e4 e5 2.f4 exf4 3.Nf3 Be7 4.Bc4 Bh4+ 5.g3 fxg3 6.O-O), and the Four Pawns Variation in the King’s Indian Defence (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f4) and the Four Pawns Attack in the Alekhine’s Defence (1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.f4).

1-0 (White has a piece, two pins, and all the attacking chances; Black has nothing.)
But this, the opening names – not the opening play – can get boring.
So …
Some openings are named after the first person who was successful with the opening moves. Others are named after a player or student of the game who first published the analysis.
Opening names such as Alekhine’s Defence (1.e4 Nf6), Fischer’s Defence in the King’s Gambit (1.e4 e5 2.f4 exf4 3.Nf3 and now 3…d6 instead of the usual 3…g5), Larsen’s Opening (1.b3), the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 Bb5), the Marshall Attack (a variation of the Ruy Lopez going 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 O-O 8.c3 d5), the Albin Counter- Gambit (1.d4 d5 2.c4 e5), Anderssen’s Opening (1.a3), the Najdorf (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6), and the Benko Gambit (1.d4 Nf6 2.c4 c5 3.d5 b5).
And that’s just for starters.
We also have the Smith-Morra (1.e4 c5 2.d4 cxd4 3.c3 – actually named after two players), the Caro-Kann (1. e4 c6, another opening named after two players), the von Hennig-Schara Gambit (yet another opening named after two players):

The Greco-Counter Gambit, by the way, is named after Greco who the first known person to write about the openings. The opening moves are 1.e4 e5 2.Nf3 f5!?. And the opening is also known as the Latvian Gambit.
This is a good time to segue into another area where chess openings are named after not just one or two players, but after a group of localized players who studied and popularized these openings. Not only do we have the Latvian, but also the Budapest (1.d4 Nf6 2.c4 e5), the French (1.e4 e6), and the English (1.c4).
Making things interesting is that some openings are named after cities and countries. We have the Catalan (1.d4 Nf6 2.c4 e6 3.g3), the Saragossa (1.c3), the Italian (1.e4 e5 2.Nf3 Nc6 3.Bc4), the Berlin Defence (1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6), the Vienna (1.e4 e5 2.Nc3), and the London (1.d4 Nf6 and White will play an early .Bf4).
Openings are also named after animals. Most players know of the Dragon (1.e4 c5 2.Nf3 and Black will soon play …g6, …Bg7, and usually …Nf6).

And some might even know the Chameleon (1.e4 c5 2.Nc3 Nc6 3.Nce2, and now White can continue with the Closed Sicilian with .d3 and .g3, or the Open Sicilian with .d4 cxd4 .Nxd4).
But how many players are familiar with the Elephant Gambit (1.e4 e5 2.Nf3 d5), the Orangutan (1.b4), the Pterodactyl Variation (1.d4 g6 2.c4 Bg7 3.Nc3 d6 4.e4 c5 5.Nf3 Qa5), or the Vulture Defence (1.d4 c5 2.d5 Nf6 3.c4 Ne4)?
Some players would mistakenly add the Bird (1.f4). But this opening was named after the English player, Henry Edward Bird (1830–1908).
But there are some opening names that are mysterious.
For example, the opening moves 1.d4 Nf6 are collectively known as the Indian Defences, such as the King’s Indian Defence, the Queen’s Indian, the Nimzo-Indian, the Old Indian. But why? We don’t know either.
And who knows where the Fried Liver Attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7)? It is said that Black, playing this variation, is dead as a piece of fried liver But, why Fried Liver and not, say, Fried Chicken or even Fried Zucchini? Surely, more people know what chicken and zucchini than Fried Liver? Maybe Fried Liver is less desirable or digestible? And Black is surely not dead after taking the knight on f7 – there are ways for him to fight on, and even to win. Ok, back to tropic.
We also have the Benoni (1.d4 Nf6 2.c4 c5 3.d5). Where did that name come from and how did it become popular? We know the latter comes from “a Hebrew term meaning “son of my sorrow” (cf. Genesis 35:18) – the name of an 1825 book by Aaron Reinganum about several defenses against the King’s Gambit and the Queen’s Gambit”, as least according to Wikipedia. But why and how did it become popular if it concerns itself with the Queen’s Gambit?
Finally, we have the Halloween Gambit (1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Nxe5), where it is said that this gambit is scary. We agree – but to which side?
