parità, ed è definita dal regolamento degli scacchi della <a href="/wiki/Federazione_Internazionale_degli_Scacchi" title="Federazione Internazionale degli Scacchi">FIDE</a>. </p><p>Ciò può avvenire sia per il reciproco accordo dei giocatori che decidono di porre fine alla sfida ritenendo che non sia possibile costringere l'avversario alla sconfitta, sia per situazioni oggettive previste dal regolamento che vengono a verificarsi durante la partita e che devono essere portate all'attenzione dell'arbitro da parte del giocatore che in quel momento ha il tratto per pretendere l'immediata sospensione della partita. </p><p>In gergo scacchistico, dalla parola "patta" sono ancora usati i verbi "pattare" ed il più raro "impattare" col significato di terminare in parità, ma anche col significato più attivo di riuscire a guadagnare una parità da parte del giocatore che è in netto svantaggio o addirittura non ha più possibilità di vincere<sup id="cite_ref-1" class="reference"><a

Tale regola sottintende che nel caso in cui il giocatore in vantaggio possieda oltre al re almeno un pedone, egli vincerà in quanto tale pezzo è sempre promuovibile in un pezzo pesante (<a href="/wiki/Donna_(scacchi)" title="Donna (scacchi)">donna</a> o <a href="/wiki/Torre_(scacchi)" title="Torre (scacchi)">torre</a>) nel caso di peggior difesa dell'avversario. Quando il giocatore in vantaggio ha invece solo un pezzo leggero (<a href="/wiki/Cavallo_(scacchi)" title="Cavallo (scacchi)">cavallo</a> o <a href="/wiki/Alfiere_(scacchi)" title="Alfiere (scacchi)">alfiere</a>) egli vince tale partita nel caso che il suo avversario possieda ancora un pezzo leggero o un pedone, in quanto ciò consente sempre una peggior difesa che porti allo scacco matto. Lo <a href="/wiki/Scacco_matto" title="Scacco matto">scacco matto</a> è possibile anche nel caso che il pezzo leggero sia un cavallo e l'avversario abbia esaurito il tempo con una torre a disposizione, mentre la partita finisce in parità in caso di alfiere contro torre o di pezzo leggero contro donna.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Forzare_la_patta">Forzare la patta</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Patta_(scacchi)&veaction=edit&section=9" title="Modifica la sezione Forzare la patta" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Patta_(scacchi)&action=edit&section=9" title="Edit section's source code: Forzare la patta"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Si dice "forzare la patta" quando il giocatore in svantaggio di materiale, con una combinazione di mosse a cui corrispondono mosse obbligate da parte dell'avversario, riesce ad arrivare ad una situazione di patta per ripetizione di posizione. </p> <div class="mw-heading mw-heading2"><h2 id="Note">Note</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Patta_(scacchi)&veaction=edit&section=10" title="Modifica la sezione Note" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Patta_(scacchi)&action=edit&section=10" title="Edit section's source code: Note"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1"><b>^</b></a> <span class="reference-text"><a rel="nofollow" class="external text" href="https://www.treccani.it/vocabolario/impattare1/">Impattare sul vocabolario Treccani</a></span> </li> <li id="cite_note-2"><a href="#cite_ref-2"><b>^</b></a> <span class="reference-text"><a rel="nofollow" class="external text" href="https://www.adcrusca.it/theke/schedaoggetto.asp?idgestore=4&idoggetto=31011">Testo del 1899 sullo stallo negli scacchi contenente il termine impattare</a></span> </li> <li id="cite_note-3"><a href="#cite_ref-3"><b>^</b></a> <span class="reference-text">Regolamento degli scacchi, art. 9.6.1</span> </li> <li id="cite_note-4"><a href="#cite_ref-4"><b>^</b></a> <span class="reference-text">Regolamento degli scacchi, art. 9.6.2</span> </li> <li id="cite_note-ref_A-5"><span class="mw-cite-backlink"><b>^</b> <sup><i><a href="#cite_ref-ref_A_5-0">a</a></i></sup> <sup><i><a href="#cite_ref-ref_A_5-1">b</a></i></sup></span> <span class="reference-text">Regolamento degli scacchi, art. 5.1.2</span> </li> <li id="cite_note-6"><a href="#cite_ref-6"><b>^</b></a> <span class="reference-text">Regolamento degli scacchi, art. 6.9</span> </li> <li id="cite_note-7"><a href="#cite_ref-7"><b>^</b></a> <span class="reference-text"><cite class="citation web" style="font-style:normal"> <a rel="nofollow" class="external text" href="https://chess24.com/en/read/news/what-happened-in-carlsen-vs-firouzja"><span style="font-style:italic;">What happened in Carlsen vs. Firouzja?</span></a>, su <span style="font-style:italic;">chess24.com</span>, 2 gennaio 2020. <small>URL consultato il 1º dicembre 2020</small>.</cite></span> </li> </ol></div> <div class="mw-heading mw-heading2"><h2 id="Collegamenti_esterni">Collegamenti esterni</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Patta_(scacchi)&veaction=edit&section=11" title="Modifica la sezione Collegamenti esterni" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Patta_(scacchi)&action=edit&section=11" title="Edit section's source code: Collegamenti esterni"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>(<span style="font-weight:bolder;
