'Miracle Boy' Shin Sang-moon secured his first-ever semifinal appearance on the 28th after a 3-0 victory over Yoon Soo-chul in the quarterfinals of the Google Play ASL Season 21, held at Freec Up Studio in Daechi-dong, Seoul. From the first set to the third, Shin dominated Yoon through solid play and superior psychological warfare, steering the matches exactly as he intended.

Below is the full transcript of Shin Sang-moon's post-match interview.

Q. How do you feel about reaching the semifinals after a 3-0 win over Yoon Soo-chul?

I only thought about winning 3-0, but now that it's actually happened, I'm a bit dazed. I lost a lot during practice, but while I was showering today, something new occurred to me, so I changed my approach. Everything went exactly as I planned.

Q. Your basic game plan today seemed to make your opponent impatient while you prepared for a long game. Why did you choose this approach?

I originally intended to attack first. But the observer spotted my factory early, so I figured the Protoss player would try to squeeze out a build.

Q. In the knockout stage, you prepared a 4-factory timing attack in the first set. It might have been a bit ambiguous to call it a 'timing rush,' right?

It wasn't an all-in rush. Just having an extra factory doesn't guarantee a win. I thought that as long as I traded units efficiently and managed my losses well, I would have the advantage.

Q. In the second set, you used a build similar to the first to play mind games, making it look like you were going for a timing attack while preparing for an even-footing engagement.

Q. Your best finish during your active career was the quarterfinals. You've broken that record by reaching the semifinals?

I should have reached this stage even back when I was an active pro. At the time, I was arrogant without even realizing it, which is why I kept failing to cross that threshold.

Q. You've been making it to the main stage every three years. What is the secret to shaking off your previous slumps this season?

In the past, I couldn't keep up with the game's meta. But right now, the meta is exactly my style.

Q. Your next opponent is 'Jjapze' Park Sang-hyun, who is considered the strongest Zerg player right now. You have a reputation for using 2-Starport builds in Zerg matchups; do you plan to use that for psychological warfare?

He's the defending champion and a very talented player. I think the key will be to prevent him from playing his own game. I'll need to use a lot of mind games. I'm confident.

Q. Any final words?

The practice process for the quarterfinals wasn't easy. I'll make sure the process and the results for the semifinals are even better.
