Underdog - chess term

Underdog

Definition

In chess, an underdog is the player perceived to be the weaker side before a game or match, usually due to a lower rating, title, or reputation. The stronger player is often called the favorite or rating favorite. The underdog label reflects expectations, not inevitabilities—chess history is full of underdog upsets that flipped predictions on their head.

Usage in Chess

Players, commentators, and writers use “underdog” to frame match dynamics and strategy. You might hear: “As the underdog, she chose a sharp Sicilian to create practical chances,” or “The underdog secured a half-point with a fortress.” Tournament previews frequently highlight underdogs who can play the role of giant killer by defeating a rating favorite. Related vocabulary includes Upset, Giant killer, Rating favorite, Practical chances, and Swindle.

Strategic Significance: How Underdogs Can Score

Approach and psychology matter. When you’re the underdog, your goal is to maximize practical winning chances or secure a reliable draw, depending on the situation and format (classical, rapid, blitz, or bullet).

  • Steer to unbalanced positions. Choose openings that create asymmetry and long-term imbalances (opposite-side castling, dynamic pawn structures, or sharp gambits). Consider “surprise” choices, a prepared novelty (a TN) or deep Home prep to get the favorite out of Book.
  • Play for time as a resource. In faster formats (Blitz, Bullet) or in Time trouble/Zeitnot scenarios, complexity can outweigh objective evaluation (the so-called “Engine eval” or CP score). Good moves under time pressure often beat perfect moves found too late.
  • Hunt practical targets: king safety and activity. Go after the enemy king, open lines, initiate a kingside pawn storm when justified, and centralize pieces to keep the favorite defending.
  • Use drawing weapons when needed. As Black, solid systems like the Berlin or Petroff can neutralize the favorite and lead to technical half-points. Build a fortress, aim for a theoretical draw, a perpetual, or reach a favorable endgame tablebase result.
  • Stay swindle-aware. Even in worse positions, set traps and perpetual motifs. A resourceful Swindle can rescue half- or full-points against overconfident favorites.

Historical and Modern Examples of Underdogs

  • Vladimir Kramnik vs. Garry Kasparov, World Championship 2000: Entering as the underdog, Kramnik neutralized Kasparov’s attacking style with the Berlin Defense and won the match without losing a game, a defining modern upset.
  • Harry Pillsbury, Hastings 1895: A relative unknown at the time, Pillsbury stunned the elite field by winning the tournament and beating multiple top players—an archetypal underdog-to-champion story.
  • Kasparov vs. Deep Blue, 1997: Public sentiment often cast IBM’s machine as the underdog after Kasparov’s 1996 triumph, yet the computer won the rematch, a landmark result in computer chess.
  • Sam Shankland, U.S. Championship 2018: Rated below the “big three” (Caruana, So, Nakamura), Shankland delivered a career-making performance to take the title—an underdog masterclass in consistency.

Example: An Underdog Trap (Elephant Trap, QGD)

Traps are classic underdog tools to punish overconfident or “bookish” play. In the Queen’s Gambit Declined, if White greedily tries to win a pawn, Black can spring the Elephant Trap.

Key idea: After 6. Nxd5?? Black reveals a tactical refutation, gaining material.

Even a rating underdog can win quickly if the favorite forgets a tactical nuance.

Practical Checklist for Underdogs

  • Opening selection: choose lines that you know better than your opponent; consider offbeat weapons that are solid but less expected.
  • Time management: avoid time sinks; choose plans you can play fast; exploit increments and endgame transitions.
  • Fight for initiative: activity and threats force the favorite to solve problems over the board (OTB), increasing your practical chances.
  • Resourcefulness: look for perpetuals, fortresses, and tactical counterblows at every stage.
  • Psychology: don’t play your opponent’s reputation—play the position. A “small edge” for a favorite isn’t decisive if you keep counterplay.

Interesting Facts and Anecdotes

  • Many “giant killer” performances come in open Swiss tournaments where rating favorites face in-form underdogs early. One win can spark a career-defining result.
  • In faster time controls, volatility increases. Upsets are far more common in blitz and bullet, where quick intuition and nerves often trump deep calculation.
  • Modern preparation blurs underdog/favorite lines: strong Home prep and a timely TN can neutralize a superior opponent right out of the opening.

Example Positions to Visualize

  • Fortress save: As Black in a rook vs rook-and-pawn endgame, the weaker side builds a barrier with king on f7 and rook checking from behind the passed pawn. The favorite “can’t make progress,” illustrating how underdogs earn half-points with precise defense.
  • Initiative gambit: As White after 1. e4 c5 2. d4 cxd4 3. c3, the Smith-Morra Gambit trades a pawn for rapid development and open lines—classic underdog play to seize initiative against the Sicilian.
  • Berlin “drawing weapon”: As Black in the Ruy Lopez Berlin, the underdog simplifies into a queenless middlegame with sturdy structure, aiming to neutralize a stronger attacker before probing for counterplay.

From Kramnik’s Berlin to Pillsbury’s breakout and countless swindles in time scrambles, underdogs remind us that chess isn’t just about evaluation—it’s about problem-solving under pressure.
