Undermining (chess)
Undermining (also known as removal of the guard, or removing the defender) is a chess tactic in which a defensive piece is captured, leaving one of the opponent's pieces undefended or under-defended. The opponent has the unpalatable choice of recapturing or saving the undefended piece. A possible response is to sacrifice the piece whose defense was undermined before capturing the piece which just took the defender. Example Kramnik– Topalov in the seventh round of the 2004 Linares chess tournament reached the diagrammed position with White to play. The black knight on a4 is defended only by the black pawn on b5. White undermined the knight with 1. Bxb5. The game continued 1... Rxb5 2. Rxa4, with a net gain of a pawn for White. Black may attempt 1...Nxb2??, disposing of the unguarded knight and hoping for 2.Kxb2 Rxb5+ to regain the lost pawn. However, after 2.Rb3 Black can only save the knight with 2…Rxb5 3.Rxb5, leaving White an exchange up instead of just a pawn. See als ...

Chess Tactic
In chess, a tactic is a sequence of moves that each makes one or more immediate threats ─ that is, a check, a material threat, a checkmating sequence threat, or the threat of another tactic ─ which culminates in the opponent being unable to respond to all of the threats without conceding an immediate benefit to the opponent. Most often, the immediate benefit takes the form of a material advantage or checkmating attack; however, some tactics are used for defensive purposes and can salvage material that would otherwise be lost, or to induce stalemate in an otherwise lost position. Tactics are usually contrasted with strategy, whereby the individual moves by themselves don't make indefensible threats, and the cumulative advantage of the moves takes longer to be capitalised on. In rough terms, the dichotomy can be summarised as tactics concerning short-term play and strategy concerning long-term play. Examples of strategic advantages are weaknesses in, compromised pawn structure i ...

Linares Chess Tournament
The Linares International Chess Tournament (Spanish: ''Torneo Internacional de Ajedrez Ciudad de Linares'') was an annual chess tournament, usually played around the end of February, which takes its name from the city of Linares in the Jaén province of Andalusia, Spain, in which it was held. It is sometimes described as the Wimbledon of chess, being one of the strongest annual tournaments held on the ''de facto'' chess tour, along with the "Tata Steel" (Wijk aan Zee), Tal Memorial and Dortmund events. The Linares tournament began in 1978 and was held annually from 1988 to 2010 (with the exception of 1996). Since 2010, the tournament has not been held for financial reasons. History The event, sponsored by Spanish businessman Luis Rentero, was first held in 1978. At that time it was not an elite event and was won by the relatively unknown Swede Jaan Eslon, on tie-break from the Argentine Roberto Luis Debarnot). After the following year's event, it was held every other year u ...

The Exchange (chess)
In chess, the exchange is a situation in which one player exchanges a (i.e. a bishop or knight) for a rook. The side which wins the rook is said to have ''won the exchange'', while the other player has ''lost the exchange'', since the rook is usually more valuable. Alternatively, the side having a rook for a minor piece is said to be ''up the exchange'', and the other player is ''down the exchange''. The opposing captures often happen on consecutive moves, although this is not strictly necessary. It is generally detrimental to lose the exchange, although occasionally one may find reason to purposely do so; the result is an ''exchange sacrifice'' (see below). The ''minor exchange'' is an uncommon term for the exchange of a bishop and knight. "The exchange" differs from the more general "exchange" or "an exchange", which refers to the loss and subsequent gain of arbitrary pieces, for example to "exchange queens" would mean that each side's queen is . Value of the exchange ...

Deflection (chess)
Deflection in chess is a tactic that forces an opposing piece to leave the square, rank or file it occupies, thus exposing the king or a valuable piece. It is typically used in the context of a combination or attack, where the deflected piece is critical to the defence. Deflection may be used as a gambit to cause an opponent's piece to move to a less suitable square. Deflections are often used as part of a combination which may involve other types of chess tactics In chess, a tactic is a sequence of moves that each makes one or more immediate threats ─ that is, a check, a material threat, a checkmating sequence threat, or the threat of another tactic ─ which culminates in the opponent being unable to ... as well. If the deflected piece happens to be an overworked piece then the opponent's defense instantly crumbles, making victory imminent to the one who employed the deflection.
