Chiswick stormed to another convincing victory as they enjoyed the perfect build-up to the London and SE Intermediate Cup Final against Maidstone by beating HAC 56-19.
The Dukes Meadow side reached the regional final by coming from behind to beat Crowborough 17-10 in the semi-finals last month, and could now be just one step from Twickenham.
Victory over Maidstone would put them into the national semis, which could be held at the home of rugby, and a further win would get them into the national final, which will definitely be held there.
HAC failed to cope with the strong running of Chiswick forwards Sam Leslie-Miller, Jon Joyce and Mikhail Ahola in particular.
Simon Hallett went over for the first try and converted it himself before Joyce and Dan Godfrey went over before the break to give the Dukes Meadow side a comfortable lead at the break.
But HAC came back after the interval and closed the gap from 22-0 to 32-19, with George Dimitriadis keeping HAC away from touching distance.
However, Chiswick exerted their dominance and Tom Steer, Leslie-Miller, Riki Darroch and Josh Noble touched down to put the game beyond doubt.
Grasshoppers survived a second half defensive meltdown to record a 37-29 home victory against Stevenage.

Chris Roberts, Callum McCormack, Tom Woodhouse and Louis Brown touched down to give Grasshoppers a comfortable lead.
Stevenage hit back, but Luke Davies and Martin Crossan went over to give the home side the win.
