Gough, the 32-year-old world No17 and former world No5 who has recently moved from Nottingham to Crowthorne in Berkshire, is making his first appearance in the semi-finals since reaching the Nationals final in 1997. In the longest match of the tournament, Gough upset the Nottingham-based world No4 12-15 15-11 15-7 4-15 15-11 in 93 minutes after coming back from 4-6 down in the fifth. "It's great when you have a perfect game and that's what it felt like in the third," said the jubilant Newport-born Welshman afterwards. "John's had a tough week after reaching the final of the Swedish Open, so I knew it would be possible to take him - and in the end I think I was just more hungry for it than he was," added Gough. "In the final points of the game, I was also mindful of my six-year-old son Jayden telling me today that I had to come home with a trophy!" Gough will face Lee Beachill in the semi-finals. The third seed from Pontefract in Yorkshire, beat Welshman David Evans 15-11 9-15 15-10 15-11 in 80 minutes to keep alive his bid to win a record third successive men's title. "He's such a dangerous player when he's relaxed and that's the way David seems to be in this tournament," said the 25-year-old Yorkshireman on his personal website www.LeeBeachill.com "I played well in the first game to close it out, then was disappointed with myself in the second when David took control. My coach Malcolm Willstrop pointed out between games that I was playing too much down the back-hand side - where David is strong. I managed to switch the play around a bit after that, and as I controlled the length more, so my confidence grew," said the world No8. It was the pair's first meeting since Beachill beat the tall Welshman, ranked 22 in the world, on the same court in the Commonwealth Games in July - though Evans was also the last player to record a victory over Beachill in the Nationals, in February 2000. Norfolk's Cassie Jackman is one match away from her sixth successive final appearance after a 9-4 9-1 9-5 victory over England team-mate and sixth seed Stephanie Brind. The former world No1 and world champion from Norwich, who is making her comeback after a second career-threatening back operation last September, was in control throughout the 31-minute match. "You see things in a new light after the low I went through last year just after the surgery - in absolute agony and having to have everything done for me, even being dressed," said the clearly rejuvenated 30-year-old. "I just love squash and it's just great to back in the swing of things after such a long time away - you appreciate things more. I was pretty pleased with the way I played tonight, but I know I've still got a lot of work to do - particularly on my fitness," Jackman, the third seed, added. Jackman now faces Tania Bailey, the second seed from Stamford in Lincolnshire - six days after beating her England No1 successor in the final of the Grantham Open. Bailey, in only her second ever National Championships win after four successive first round defeats since 1997, beat Yorkshire veteran Suzanne Horner 9-3 9-2 9-0 in 27 minutes. The remarkable world No15 from Wakefield, who will celebrate her 40th birthday in little more than a week, was competing in her 13th successive Nationals quarter-final and making her 23rd appearance in the event since 1978 - the year before Bailey was born. "I always play well on this court," said the Lincolnshire lass of the all-glass showcourt on which she claimed a Commonwealth Games silver medal in the Women's Doubles last August, and a final place in the British Open four months earlier. "I felt very comfortable tonight - and am glad to be winning matches at last in this event after doing so miserably over the past few years."
