You can link from it sure, but since you can’t really combo into F+MK I’d say that roughly half the time it is going to be blocked. In that case, it doesn’t combo into anything. But even if it is blocked, you have just dashed up right in their face and you have a small amount of frame advantage so you can keep pressing the attack.
People really underestimate the importance of moves that move you forwards in SF. It applies pressure, and people have to respond to that pressure… by hitting someone with a F+MK, you push them back towards the corner; you close to Abel’s deadliest range (TT range); it is a fast, relatively low-risk move so even if it misses, it is very difficult to punish; it gives you a ton of mix-up opportunities.
It is the pressure and chance for mix-ups that makes it so valuable. There are a lot of things that can happen after a F+MK…
- they mash a reversal - especially common against shotos. This beats everything Abel can do from a F+MK, and knowing this, you can bait it, block, and punish.
- they mash normal throw. This loses to TT, but will beat all of Abel’s normals except possibly standing fierce. Usually, TT is such a threat that people will not do this but they might know that TT’s whiffing animation is very long, and then anticipate a normal throw instead of a TT
- they attempt to jump out. This loses to standing close roundhouse (100 damage) and falling sky (160+ damage). Vega gets out of F+MK mixups for free using jump back fierce unless you have perfect timing on a close roundhouse.
- they stand there and block high. This is when you hit them with a low short, which then lets you combo afterwards (c.jab, c.jab, s.far strong), set up ticks into TT, or set up another F+MK (c.jab, c.jab, f+mk is the best bet - on a landed c.jab f+mk becomes a very nice frame trap). Also, blocking loses to TT every time.
- they stand there and block low. Once again a TT opportunity, but you can also standing close roundhouse as an overhead.
- they mash jab, especially common against anyone with a 3 frame jab who needs EX for a good reversal. This loses to EX TT but beats everything else Abel can do.
So now you know why F+MK is so good. Abel is a little like Zangief; the tornado throw on its own is really strong but it is the threat of a tornado throw that is really useful. Once you land the F+MK, the natural follow up is a TT and you need to take advantage of the panic that causes to start doing your damage. As soon as somebody is within Abel’s reach they want to get out, and you have to try and guess how they are going to try and escape the situation so that you can punish their choice and keep up the pressure.
But then there is the problem of landing a F+MK in the first place. People with experience against Abel will see it coming and then shoryu, which kind of puts a damper on trying F+MK again. So again, you gotta yomi that shit and set up with the F+MK with a c.jab then bait and punish
