The 34-year-old South African believes that the format will create a climatic final day's action as the final 24 take each other on in a knockout matchplay tournament. "You'll see probably a few more riskier shots which you wouldn't see in stroke play. It should be a very exciting Sunday," added Oosthuizen. The top eight go straight into the last 16, while the remaining 16 will be drawn together in head-to-head matches to decide the other eight spots. From there it is straight knockout until there is a winner. According to the World Super 6 website, any knockout matches 'not decided after six holes of matchplay will be decided by playing the new shootout hole'. The 'shootout hole' will be 90m long and see 'a new tee placed adjacent to the 18th fairway and utilising the 18th green'.

In England, there were 860,900 adults playing in 2009-10 compared to 740,000 in 2014-15 according to Sport England. The British Golf Industry Association is attempting to make courses more family friendly.
