Whenever I do st.MK->cr.RH I’m at a range where the st.MK connects, but invariably it’s outside their throw range. It works so well because people tend to mash after the blocked st.MK, as they expect a throw coming, yet they’re way outside throw range. Works great even against Dic, Sim who have great throw ranges but no reversal move.
I love doing st.MK->cr.RH because it’s just a solid blockstring. People fall for the cr.RH surprisingly often. And if they block it, you can often catch them by surprise with a super immediately afterwards. I like doing this against Dic because often they try to reply with scissor kick immediately after blocking the cr.RH.
As a side note, the Dic matchup is great because you can do so many variations on blockstrings thanks to his lack of reversal move. Can be fun pressure mindgames with jump-in leading to blockstring, into throw, knockdown, or whiffed rush into normal move or another jump-in etc etc.
I have to check the frame data too, but I could swear that when Dic is crouching, his hitbox is slightly further away. Against Ryu, you can do a jump-in at any range, land and do cr.Strong, and the cr.Strong will connect. Against Dic, often the cr.Strong won’t connect. Probably just my imagination though. That said, all the more reason to use st.MK imo.
