Fact num1: Queen's Gambit

The objective of the chess move, Queen’s Gambit, is to temporarily sacrifice a pawn to gain control of the center of the board. This choice on Beth’s part ties directly to her past, as the gambit is a hedge of sorts, a sacrifice that one is required to give up early on in order to win the final game.

This move was created in 1968 by an unknown player.

Fact num2: Sicilian Defence

The Sicilian Defense allows Black to attack the d4 square and fight for the center without the symmetry that results from 1... e5. This generally leads to unbalanced positions and usually leaves black with a central pawn majority after trading his c-pawn for White's d-pawn.

This move was created by  Giulio Cesare Polerio in 1594

Fact num3: Scholar's Mate

In chess, a scholar’s mate is a four-move checkmate in which you use your white-square bishop and queen in a mating attack targeting the opponent’s f-pawn (f2 if white; f7 if black). The f-pawn is considered among the weakest pieces on the chessboard because it is only defended by the king. By exploiting your opponent’s most vulnerable point early on, you can trap them in an early checkmate.

This move was made by Francis Beale  in 1656.
