this is just a very quick basic beginner friendly string that is very easy to execute, while still leave room open on what other things you can do. there are perhaps dozens of ways you can go about pressure strings but ultimately that's up for you as a player to decide what to use and how well it works per opponent. and yes if people mash after blocking 2p/2s then just frametrap them further to get counter hits. with 2p ch 2s 6H leads into GV for example or 2s ch 6H leads into Bandit Bringer Fafnir / Bandit Bringer dustloop routes. You first condition your opponent to stop mashing by frame trapping , if they don't stop mashing they'll just end up dying to counter hit conversions. I'm not telling you that you must use this every time time I'm just showing one of many options about doing a very basic pressure string.
