quick is meant to be the fast option, but it only changes how repeated
attempts are handled - it still works through every variation of a
strategy regardless. For strategies built around a fake TLS handshake,
that means testing dozens of small tweaks (different TTLs, different
TCP tricks, extra padding, split positions) well past the point where
an early exit would have been possible.
The new veryquick level stops as soon as a strategy succeeds, instead
of continuing through the rest just to be thorough. It's a separate
option rather than a change to quick, so quick, standard, and force
behave exactly as they did.
Custom strategy lists are plain text, and each line gets run through
the shell - so a strategy containing certain characters (<, parentheses,
quotes) would fail unless you added quotes around it by hand. Some real,
valid strategies use exactly these characters.
Now, when a line fails for that reason, it's automatically retried in
a simpler way that doesn't care about those characters at all. You can
paste a strategy in exactly as blockcheck2 prints it and it'll just
work. Manual escaping still works too, and is tried first if you're
already doing it.
