I want to remove some text from which I know the starting characters and the 2 ending characters. The text I want to remove is part of a textfile TestEK.txt and the cleaned text should be in a new textfile Out.txt. My regex worked in an online regex tester, but not in my perlfile and I can not find out why. 

#!/usr/bin/perl -w
# Remove extra text from a PGN or Text-file.
# Aufruf: perl remove2.pl TestEK.txt > Out.txt

# This is TestEK.txt:
# 1. Ka6 ({Of course not} 1. b6 $2 Kb7 $11) 1... Kb8 (1... f4 2. b6 $1
+8) {[%tqu "What is  White's next move?","","",g3,"",0,b6,"misses the 
+win:",0]} 2. g3 $1 13. g6 c3

# This should be the Out.txt
# 1. Ka6 ({Of course not} 1. b6 $2 Kb7 $11) 1... Kb8 (1... f4 2. b6 $1
+8) } 2. g3 $1 13. g6 c3
use strict;

my $regex =/\{\[%tqu .* ]}/;
my $subst = //;
while(<>) 
{
    my $line = $_;
    s/$regex/$subst/gi;
}
