Verbi riflessivi
Reflexive verbs

“La partita… si è tenuta a Philadelphia”
(The game… took place in Philadelphia)

The verbs “si è tenuta” and “si è alzato” are both in the reflexive form and in the passato prossimo tense. In Italian, the reflexive form is often used to express actions that the subject performs on or for themselves.

In the sentence “(la partita) si è tenuta a Philadelphia”, the reflexive form indicates that the subject (the event) took place in Philadelphia.
The past participle “tenuta” agrees in gender and number with the subject “la partita” (feminine singular). So “si è tenuta” can be translated as “took place” or “was held”.

In the sentence “Kasparov si è alzato e ha ammesso la sconfitta”, the reflexive form indicates that the subject (Kasparov) performed the action (getting up) on or for himself. “Si è alzato” can be translated as “stood up”.
