Bishops Opening, Boi & Lewis Gambit

Bishop’s Opening

Definition

The Bishop’s Opening is a King’s Pawn opening that begins with the moves 1. e4 e5 2. Bc4. By developing the king’s-bishop to c4 before bringing out the king’s-knight, White aims straight at the sensitive f7–square and keeps maximum flexibility for the rest of the army.

Typical Usage and Plans

  • Pressure on f7: The bishop on c4 eyes the weakest point in Black’s camp-–f7–-from move two.
  • Flexibility: Depending on Black’s reply, White can steer the game into Italian-Game structures (after Nf3 and d4), King’s Gambit-style attacks (after f4), or Vienna-type set-ups (with Nc3).
  • Rapid Development: The early bishop move allows quick castling (often via Nf3, 0-0) and gives White a lead in piece activity.

Strategic Significance

Although the opening is more than 400 years old—featured in the works of Greco (1620s)—modern engines still give it full theoretical respect. Because the knight on g1 is held back, Black cannot be certain what pawn structure or piece placement White will choose, making it difficult to equalise quickly.

Main Branches at a Glance

  1. 2…Nf6 3.d3 – A quiet, manoeuvring line that can transpose to the Giuoco Pianissimo.
  2. 2…Nc6 3.Nf3 – Directly enters the Italian Game if White later plays d4.
  3. 2…Bc5 – Allows gambits such as the Lewis Gambit (3.b4!?) covered below.
  4. 2…c6 – The Paw-Klutz Variation, preparing …d5 with a Caro-Kann flavour.

Historical Notes & Anecdotes

  • Paul Morphy used the Bishop’s Opening as a surprise weapon; his sparkling miniature against Louis Paulsen (New York, 1857) is a classroom staple.
  • Bobby Fischer resurrected the line in the 1960s blitz scene, enjoying the possibility of an immediate f2–f4 thrust.
  • In online bullet chess, elite players such as Hikaru Nakamura and Magnus Carlsen sometimes employ 1.e4 e5 2.Bc4 as a practical, low-maintenance weapon.

Boi

Definition

Boi is an informal, community-driven slang term that has seeped into modern chess culture through Twitch streams, YouTube commentary, and social-media memes. It is not an official theoretical term but is widely understood among online players.

How It Is Used

  • Affectionate reference to pieces: “Look at that knight, he’s my boi on f5!” – usually implying a proud, well-posted piece.
  • Cheeky nickname for a gambit or plan: Streamers may say, “Time for the Bongcloud Boi!” to hype the audience before playing 1.e4 e5 2.Ke2.
  • Label for a promising junior: Coaches occasionally call a protégé their “boi,” echoing general youth culture.

Strategic or Historical Significance

Because boi is purely colloquial, it carries no concrete theoretical weight. Its importance lies in community-building: it adds levity to coaching sessions and streams, making chess more approachable for newcomers.

Examples in Context

During the PogChamps 3 event (2021), commentator GM Robert Hess repeatedly joked about “the knight boi on g4,” which subsequently became a Reddit meme complete with photoshopped sunglasses on the knight.

Interesting Fact

The word’s adoption mirrors the way older masters used affectionate nicknames—Alexander Alekhine famously called his queen “la dama” in private notes. Today’s “boi” is simply the meme-era continuation of that tradition.

Lewis Gambit (in the Bishop’s Opening)

Definition

The Lewis Gambit is an aggressive pawn sacrifice that arises after 1. e4 e5 2. Bc4 Bc5 3. b4!? White offers the b-pawn to lure Black’s bishop off-side, gaining time to seize the centre—much like the better-known Evans Gambit but without an early Nf3. The gambit is named after the 19th-century English master and author William Lewis, who analysed the line extensively in his 1844 treatise.

Move Order & Critical Position


After 4.c3 Ba5 5.d4! White gains a big centre and open diagonals at the cost of a pawn.

Strategic Themes

  • Tempo Gain: 3…Bxb4 pulls the bishop away from c5; later d4 chases it again, letting White develop rapidly.
  • Open Lines: The half-open f-file and open diagonals (a2–g8 and c1–h6) can lead to swift attacks on the king.
  • Central Control: The d- and e-pawns march to occupy key squares, often supported by Nf3 and 0-0.

Critical Defences for Black

  1. 3…Bxb4 4.c3 Ba5 5.Nf3 aiming for 0-0 and Re1.
  2. Declining with 3…Bb6 – keeps the pawn structure intact but cedes space.
  3. Counter-gambit 3…d5!? 4.Bxd5 Nf6 – strikes back in the centre immediately.

Historical & Practical Significance

  • Though celebrated in the 1800s, modern grandmasters seldom employ the Lewis Gambit in classical play because engines confirm that Black can equalise with accurate defence.
  • In rapid and blitz, however, the line remains a potent surprise weapon; GM Baadur Jobava scored several online scalps with it in 2020-2022 arena events.
  • William Lewis himself used the gambit in off-hand games at the London Chess Club, delighting spectators with daring king-side assaults.

Interesting Tidbits

  • Because the Lewis Gambit occurs via the Bishop’s Opening, its ECO classification is C23/C24 rather than within the C50-series where the Evans Gambit is catalogued.
  • Many amateurs incorrectly call 3.b4 in the Italian Game (after 3.Bc4 Bc5 4.b4) a “Lewis Gambit”; strictly speaking, that is the Evans Gambit.
  • Some online creators dub 3.b4 the “Budget Evans” or “Evans-lite”—a playful nod to Lewis’s lesser-known lineage.
