## Chess Board Setup


1. The Basics

8x8 grid, alternating light/dark squares.

>Key rule: *Always place the board so a light square is on each player’s bottom-right.

2. Coordinates

Files (columns): Labeled a to h (left to right).

Ranks (rows): Numbered 1 to 8 (White’s side = 1, Black’s = 8).

> Notation: Squares are file + rank (e.g., e4, a7).

3. Piece Placement

Black (Top): a8: Rook b8: Knight c8: Bishop d8: Queen

e8: King f8: Bishop g8: Knight h8: Rook

Rank 7: All pawns (a7-h7)

White (Bottom): a1: Rook b1: Knight c1: Bishop d1: Queen

e1: King f1: Bishop g1: Knight h1: Rook

Rank 2: All pawns (a2-h2)

> Quick Tip: Queens start on their color (Whiteon d1, Black on d8).

## Checkmate, stalemate & draws

Chess is a two-player strategy game where the ultimate goal is to checkmate your opponent’s king. However, games can also end in a stalemate or draw under specific conditions.

1. Checkmate (Winning the Game)

- Definition: The enemy king is in check (under attack) and has no legal moves to escape.

- Result: The game ends immediately—the player delivering checkmate wins.

1. Stalemate (Draw)

- Definition: The player whose turn it is has no legal moves, but their king is not in check.

- Result: The game is a draw (no winner).

> Common Causes:

>- A lone king with no moves left.

>- Poor pawn structure blocking all options.

3. Other Draws

Games can also end in a draw due to:

- Insufficient Material

- Only kings remain.

- King + bishop vs. king (no possible checkmate).

- Threefold Repetition

- The same position occurs 3 times (with the same player to move).

- 50-Move Rule

- No pawn moves or captures in 50 consecutive moves (by both players).

- Agreement

- Players mutually agree to a draw.

Key differences:

| Term | King in Check? | Legal Moves? | Result |

| --------- | -------------- | ------------ | -------- |

| Checkmate | Yes | No | Win/Loss |

| Stalemate | No | No | Draw |

| Draw | N/A | N/A | Tie |

## Chess history

1. Ancient Origins (6th Century)

- Birthplace: Northern India (as Chaturanga), meaning "four divisions" (infantry, cavalry, elephants, chariots—early versions of pawns, knights, bishops, rooks).

- Spread: Reached Persia as Shatranj by 600 AD, where key rules (like "check" and "checkmate") emerged.

> Fun fact: "Checkmate" comes from Persian "Shah Mat" ("the king is helpless").

2. Medieval Europe (9th–15th Century)

- Rebranding: Arabs brought chess to Spain by 1000 AD; Europeans adapted pieces to feudal society:

Elephants → Bishops

Viziers → Queens (weak at first—could only move one square!)

- Major Change: By 1475, the queen became the most powerful piece ("Mad Queen Chess"), speeding up the game.

3. Modern Chess (1850–Present)

- Standardization: First official world championship (1886, Wilhelm Steinitz vs. Johannes Zukertort).

- Computers: IBM’s Deep Blue defeated Garry Kasparov in 1997, revolutionizing AI.

- Today: Online platforms (Chess.com, Lichess) and pop culture (The Queen’s Gambit) fuel a global boom.

>Did You Know?

>

> - The longest possible chess game is 5,949 moves (theoretical limit).

>

> - The longest recorded game was 269 moves, 1989 Nikolić vs. Arsović.

>

> - The oldest recorded chess opening (1.e4) appears in a 1490 Spanish manuscript.
