Andy Murray will hope to continue his winning run against Tomas Berdych as he bids for a place in a third Wimbledon final.
Berdych was one of Murray's most difficult opponents earlier in his career and won six of their first 10 meetings but the Scot has since chalked up four successive victories, losing only one set.
The Czech attributed the change in fortunes to Murray adopting a more aggressive approach.
The Scot said: "I know it will be a tough match. I played well against him the last couple of years.
"It's nice that the players I'm playing against say I'm playing more aggressive because everyone's only said I've played aggressive when Ivan (Lendl) has been coaching me.
"The last few years I have been playing more aggressive tennis, playing with a little bit more variety, for sure. That's worked well against him."
This will be their fourth meeting at a grand slam. Berdych won the first at the French Open in 2010 but lost to Murray in the last four at the US Open in 2012, where the Scot won his first grand slam title, and the Australian Open last year.
"We've never played on grass before," said Murray. "We've played a few times over the last couple of years on different surfaces, but never on grass.
"I'll have to have a look and see some of his matches to get an idea of maybe some of the things he does differently on the grass courts, what his strengths are, maybe some of the things he struggles with a bit.
"Obviously he's a big guy who serves well. When he's dictating the points, he hits a big, big ball. He's a powerful guy. Ideally, I don't want to have him dictating all of the points because then I'll be doing a lot of running."
Berdych is looking to replicate his run here in 2010, when he reached his first and so far only slam final by defeating Roger Federer and Novak Djokovic before losing to Rafael Nadal.
He is also taking heart from his performances against Murray in New York and Melbourne, where he won the opening set both times.
The 30-year-old said: "Definitely those are the experiences from 2010 that I will try to look back at. But mostly it's the fact that that was the first time when I showed myself that I can play well for two weeks.
"I can beat the best guys not only at the beginning of the tournament, but also in the later stages.
"There were also a couple of matches (against Murray), the one at the US Open, which was a bit unlucky for me. Also the one we played in Melbourne.
"There were chances. I think it will be a really nice opportunity for me to make it happen right here."
The winner of the clash will play either seven-time champion Federer or in-form Canadian Milos Raonic, who meet in the first semi-final.
