Chess

Chess is a two-player board game played on a chessboard, a checkered gameboard with 64 squares arranged in an eight-by-eight grid. Chess is played by millions of people worldwide, both amateurs and professionals.

Each player begins the game with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. Each of the six piece types moves differently. The most powerful piece is the queen and the least powerful piece is the pawn. The objective is to 'checkmate' the opponent's king by placing it under an inescapable threat of capture. To this end, a player's pieces are used to attack and capture the opponent's pieces, while supporting their own. In addition to checkmate, the game can be won by voluntary resignation by the opponent, which typically occurs when too much material is lost, or if checkmate appears unavoidable. A game may also result in a draw in several ways.

Chess is believed to have originated in India, some time before the 7th century; the Indian game of chaturanga is also the likely ancestor of xiangqi and shogi. The pieces took on their current powers in Spain in the late 15th century; the rules were finally standardized in the 19th century.

Ganesha (psychedelic)

Ganesha, or 2,5-dimethoxy-3,4-dimethylamphetamine, is a lesser-known psychedelic drug. It is also a substituted amphetamine. It was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 24–32 mg. The drug is usually taken orally, although other routes such as rectally may also be used. Ganesha is synthesized from 2,5-dimethoxy-3,4-dimethylbenzaldehyde. Ganesha is the amphetamine analogue of 2C-G. It is a particularly long lasting drug, with the duration listed in PiHKAL as being 18 – 24 hours, which might make it undesirable to some users. It is named after the Hindu deity, Ganesha. Very little is known about the dangers or toxicity of Ganesha. Effects of Ganesha include:
