Donkbet no river, fold? {nl2}

Trago mais uma mão que me gerou dúvidas, joguei por valor o flop e o pré-flop, até porque o vilão tem fortes tendências donkeys e tinha o top pair com um bom kicker. Porém pela atitude passiva dele, estava esperando algo, e acho que não percebi.

Aqui no river, depois da aposta dele é fold?
