I've gotta run so I'll be brief.

Your range on the flop: a naked Ad, 64s (not diamonds), Ad + a pair, set, Q + a decent diamond (Ad-KdQx, QxJd), possibly a queen/no diamond or 53 but I doubt those

His range: big diamond, set, queen, overpair with no diamond

None of those change at all by the river, except that I think your turn bet is a value bet rather than a bluff so the naked ace is probably out.

The worst hand you can have with that river push is probably AQ or an occasional bluff. The problem is that the second worst is 64. Given that, I think he can call with any flush, but has to fold the queens (on the turn, because he should know a push is probably coming on the river after that bet/remaining stack sizes, but he doesn't because he's an idiot.) If he has AA...I dunno, he's stupid but gave himself odds good enough to snap some bluffs off.
