Middlesex built up a big lead on the third day of the County Championship game with Warwickshire at Edgbaston.
Warwickshire were skittled out for 333, some 46 runs ahead.
Although, Robson and Denly both fell to Chris Wright cheaply, Chris Rogers and David Malan put on 203 for the third wicket before Rogers went for 109 caught by Chopra.
That brought a wicket for Boyd Rankin and he also took the wickets of Dexter and Rossington but he could not get Malan who ended the day 138 not out.
When play was abandoned for the day, Middlesex were on 351-5, some 305 runs ahead.
