It is often used to destroy the enemy <a href="/wiki/Pawn_structure" title="Pawn structure">pawn structure</a> (as in several variations of the <a href="/wiki/Sicilian_Defence" title="Sicilian Defence">Sicilian Defence</a> where Black <dfn><a href="/wiki/Glossary_of_chess#captures" title="Glossary of chess"><span title="See entry at: Glossary of chess § captures" style="color:inherit;" class="glossary-link">captures</span></a></dfn> a knight on c3 with a rook), to establish a minor piece on a strong square (often threatening the enemy king), to improve one's own pawn structure (creating, for example, <a href="/wiki/Connected_pawns" title="Connected pawns">connected</a> <a href="/wiki/Passed_pawn" title="Passed pawn">passed pawns</a> such as in A Yurgis–Botvinnik, 1931<sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup>), or to gain time for development. The exchange sacrifice contrasts with other <a href="/wiki/Sacrifice_(chess)" title="Sacrifice (chess)">sacrifices</a> in that during the early-middle to middle game the board is sufficiently crowded to where the rook is not as effective as an active knight or a good bishop; this is why such exchange sacrifices happen usually from moves 20 to 30, and rarely occur in the later moves. When they do occur in the endgame, it is usually to create and <a href="/wiki/Promotion_(chess)" title="Promotion (chess)">promote</a> a <a href="/wiki/Passed_pawn" title="Passed pawn">passed pawn</a>.<sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup> Subsequently, the relative importance of the pieces might be different from the standardized <a href="/wiki/Chess_piece_relative_value" title="Chess piece relative value">Chess piece relative value</a> system and takes advantage of the fluctuating values of the pieces during the progression of the game. The sacrifice might also be used to increase the influence of one's own minor pieces by eliminating opposition from their counterparts (such as in the Petrosian versus Spassky game below, where even a double exchange sacrifice was successful). A common example of this idea is the elimination an opponent's bishop, with the expectation that in doing so one's own bishop will increase in power from being unopposed on the color squares in which it resides. There is often more dynamic play and positional considerations such as pawn structure or piece placement compared to sacrifices due to a mating attack or a pawn sacrifice to gain the initiative. Sometimes the exchange can be sacrificed purely on long term positional objectives, as frequently demonstrated by former world champion <a href="/wiki/Tigran_Petrosian" title="Tigran Petrosian">Tigran

<a href="/wiki/Classicism" title="Classicism">Classicists</a> of the late nineteenth and early twentieth century claimed that two bishops versus rook and knight were equivalent. Today, the view is that a pair of bishops shouldn't be underestimated, but the rook and knight are still superior. A pair of active bishops is frequently adequate compensation for a pawn - or even the exchange in a middlegame position. Adding the better cooperation of the rook with the bishops, many Soviet theoreticians believed that, in active positions, rook and two bishops outperform two rooks and a knight. The modern consensus is that the side with the two bishops need at least a pawn when facing rook and knight, even then the side with the two bishops is <a href="/wiki/Underdog" title="Underdog">underdog</a>. <a href="/wiki/William_Steinitz" class="mw-redirect" title="William Steinitz">William Steinitz</a> reckoned that often two bishops and two pawns are superior against rook and knight. </p><p>A rook and bishop usually work better together than a rook and knight in the endgame.<sup id="cite_ref-30" class="reference"><a href="#cite_note-30"><span class="cite-bracket">[</span>30<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-31" class="reference"><a href="#cite_note-31"><span class="cite-bracket">[</span>31<span class="cite-bracket">]</span></a></sup> <a href="/wiki/Jos%C3%A9_Ra%C3%BAl_Capablanca" title="José Raúl Capablanca">José Raúl Capablanca</a> stated that a queen and knight work better together than a queen and bishop in the endgame.<sup id="cite_ref-32" class="reference"><a href="#cite_note-32"><span class="cite-bracket">[</span>32<span class="cite-bracket">]</span></a></sup> More recently, <a href="/wiki/John_L._Watson" title="John L.
