Partida (2005) 37 Cal.4th 428, 433; see id. at p. 434 ["The objection requirement is necessary in criminal cases because a 'contrary rule would deprive the People of the opportunity to cure the defect at trial and would "permit the defendant to gamble on an acquittal at his trial secure in the knowledge that a conviction would be reversed on appeal."'"].) Here, in the absence of any timely objections, defendant forfeited these evidentiary challenges.
