Aloha, tennis lovers. Another edition of Fourhand is here, with videos featuring great looks at Tim Smyczek's wow-inducing backhand against Jack Sock, Stanislas Wawrinka enjoying a hockey game, the USTA's latest ad campaign, boasting the catch phrase #TennisMakesYou, and Judy Murray and 400-plus others engaging in the world-record largest tennis clinic ever.

STAN DELIVERS  Australian Open winner Stan Wawrinka showed for a Los Angeles Kings NHL game against the Montreal Canadiens in the City of Angels. A rinkside interview saw his ballyhooed backhand talked up on live TV, furthering that particular shot's mystique across other channels and arenas, literally.

TAKE ... THAT!  And speaking of backhands, Tim Smyczek survived Jack Sock's well-placed lob in the Indian Wells desert, matching it with a sterling cross-court winner that dipped low and swerved out wide. Changeover Tennis has the GIF to prove it.

SAFETY IN NUMBERS British Fed Cup captain and mum to Andy Murray, Judy, teamed up with friends across the pond to have a go at the Guinness World Record for largest tennis lesson. With 406 participants, the group officially broke the mark on World Tennis Day on March 3, and here's the clip to prove it:
