Wily I am pretty sure the race he won beating Trissaro was over 2000 metres at Randwick(probably the Queen Elizabeth??) pretty sure it wasn't the Tancred(over 2400 metres) Trissaro was ridden by P.B. Smith(a New Zealander who was riding in Australia at the time), Trissaro then won te Sydney Cup at his next start with John Marshall on top, I think the Queen Elizabeth (or the race Chiamare won)was run on the Saturday of the Easter weekend and then Trissaro backed up on the Monday in the Sydney Cup to win it at 10/1
Peter Cook adopted stop/start tactics on Chiamare which didn't suit the hot fav Trissaro, it was a brilliant ride!
that is from memory only because I backed Chiamare on the Saturday and Trissaro on the Monday, it was a great weekend

Chiamare was a very good horse but just below top class, Tommy always had him ready to win and exploit any weakness in the opposition(like he did with all his horses) if you were going to beat him it was after the fight or you had to out class him
