Robinson nodded home a freekick from Lewis Worsey – who enjoyed an impressive debut – on 25 minutes in a game lacking in clearcut opportunities.
Beckley had the ball in the net on 17 minutes but was flagged offside and five minutes later Reid had a great opportunity through on goal only to be denied by Sam Arnold.
After Robinson put Khalsa ahead, the tempo dipped and Jack Skinner’s badly directed effort on 35 minutes the only further action of note in the first half.
Boldmere came out with some purpose and on 49 minutes Reid had another opportunity when clear through but put his chip straight into the hands of Arnold.
Shortly afterwards, at the other end, Beckley was put through by Gaz Singh but couldn’t get his effort on target.
And almost immediately Reid came agonisingly close to drawing his side level, hitting the bar with a great effort from a tight angle after impressively carving himself an opportunity.
The final stages saw Boldmere turn up the heat in search of an equaliser. Joe Lyng headed over from a Rico Taylor corner on 75 minutes and the same player then hit the top of the bar with a header.
