I have some fairly basic questions to ask about Smoke's blockstrings.
3d12 followed by d1 is a great way of applying pressure. I know if the d1 hits I have a number of options, one of the first I realised was the potential for smoke away for run away against characters you want to maintain distance against. Are there any characters in the cast who can punish you for smoke away after hc'ing the d1? If the d1 hits, do I get a follow up 21, smoke bomb/214, smoke away for free? Also, if the d1 is blocked, how much disadvantage am I at? More than enough for them to counterpoke?
I tend to play Smoke like I play Sub-Zero now just with the obvious increased mobility and better whiff punishment, lol. I am sure I'll get better with him as I think he's a monster of a character. His footsies are 10 times better than Sub's and I've always thought of Sub as completely dependent on footsies.
Also, one more question: is Smoke's d4 as good as Sub-Zero's on hit and on block? It seems to be the exact same move with a slightly different animation. If so, that is really useful for his pressure game.
While 3d12 > d1 is a good trap, especially against opponents who are jump happy, I doubt you'll see much success with it unless you use it sparingly and with a lot of mix ups. This isn't because of any inherent obviousness so much as that us Smoke players have already abused the shit out of it and everyone knows it. After they block a d1, if they're paying attention they can punish it with their own d1 or d3 and depending on the character, this can reverse pressure on you.
On paper, the advantage on hit of d1 isn't enough to guarantee any follow up besides another d1, but in reality it can scare them into blocking allowing you to continue pressure.
If the d1 connects, the follow up smoke drift away is safe besides fast advancing specials that go full screen (ex shadow kick, ex shoulder charge, ex blade charge, kano ball, superman, etc.) Note that the regular versions of those EX moves won't go far enough and will whiff. If the d1 is blocked, and if they're frame perfect with a retaliation poke it will hit and the fast advancing specials will have more success. BUT, it's unlikely they'll commit to chasing you like that once the drift is away from them.
As far as his d4 goes, yea it's extremely similar to Sub's in terms of hit and block stun but it's slower by 4 frames or so. Sub's d4 is retardedly fast.
