Here’s a bit of a history lesson and some trivia for you guys:
cr.mk xx fireball was never called an Option Select. In fact, there was never even a name for it. It was just something that emerged from gameplay. You were never always going to connect the cr.mk, but you did the QCF + P anyway. The technique of doing a move in case (well, the default was that it was always expected to hit) the previous one connected started becoming known as “buffering a move”. Buffered moves were in fact what some people called combos. Now while buffered moves are technically Option Selects, the key difference is that with a buffered move the default is that we expect every move in the sequence to hit giving the expected outcome for that input. With an OS, the sequential moves usually only occur if the first move does not hit, and in cases of complex inputs, the secondary input may not even make sense giving the current context. Meaning that if your secondary input is QCF + K and your character has no QCF moves, then the OS is probably used to cover scenarios where the opponent avoids the first input by switching sides.
Now these techniques were only developed long after buffered moves were named. In Japan, OS’s have various names depending on the game. In SFIV, it’s called “Emilio Technique”, named of the SFIV Ken player who popularised them. However, anti-backdash OS’s themselves were already used in SFIV like after the first month. Emilio Ken popularised the more complex OS’s that involved chains into combo, or Ultra 1 if they backdashed. The more basic OSs were just called “installs” or “built-ins”. eg. a j.hk OS DP would be a jumping hard kick with a built-in Shoryu. Japanese commentators would just call this Shikomi Shoryu. Other specialised OSs also have different names like SGGK in 3S, or DED which is a special version of a buffer, but it’s an OS due to the inputs being non-sensical in the default context. The first piece written on the Web (not the newsgroups…) that I know of regarding “built-in” moves in SF (Option Selects) is from 2006.
Right, so of what use is this to anyone? Firstly, that even though it’s technically true that cr.mk xx hadou is an OS, it’s a technique that’s so in-grained into the mechanical aspects of FGs that it’s more confusing than not to call it anything but a buffered move. After all, we lived with this for 15 years without considering it to be anything particularly special.
And secondly, by applying a bit of general knowledge, we can figure out that “shikomi” is written as 仕込 in Japanese.
So what if we search for videos with the words SFV and 仕込 in the title/description?
We find SFV option selects:
