Title: Aniversario: Never Compromise
Passage: Aniversario: Never Compromise was a professional wrestling internet pay-per-view (iPPV) event produced by the Chikara promotion, that took place on June 2, 2013, at the Trocadero Theatre in Philadelphia, Pennsylvania.  The event marked Chikara's fourth iPPV, third to take place at the Trocadero Theatre and the promotion's only event to take place in Philadelphia in 2013.  Much like the previous iPPV, Under the Hood, Aniversario: Never Compromise also aired through Smart Mark Video.  Aniversario: Never Compromise celebrated Chikara's eleventh anniversary and was the first anniversary event to take place on iPPV; in the past, the promotion had celebrated its anniversaries with weekends of two shows.  The event saw all three Chikara championships being defended with one title change, where Pieces of Hate (Jigsaw and The Shard) defeated 3.0 (Scott Parker and Shane Matthews) for the Campeonatos de Parejas.  Another major match during the event saw former Campeones de Parejas, Amasis and Ophidian, end their nineteen-month storyline rivalry in a Sarcophagus match.  The event concluded with a major storyline development, where Chikara's authority figure Wink Vavasseur ended the event and shut down the promotion, while the main event was still going on in the ring, leading to the promotion going inactive for a full year.
