I feel embarrassed how long it took me to realise that salty suite is a pun. OMFG.
it took me like 3 years too...
In the NRS community we use fuzzy guard to mean when you block a certain way anticipating a mixup and you switch from crouch to stand or the other way around to cover another option because it's slower than the first. So let's say a character has an overhead/low 50/50 where the overhead is much slower than the low. In a situation where you think this mixup is coming either as a guess or it's part of a canned string you'd fuzzy guard by blocking low at first since the low is faster and you'd switch to stand block in case they do the overhead while you're safe from the low since it's time to come has already passed. So very similar to the concept in 3D fighters.
this is weirding me out because im realizing that this term has 3 possible meanings depending on your scene.
