if you treat goh like a sort of washed-up akira, you could probably play him fairly well

f,f+p:b+p+g is your f,f,f+p
b,df+p is your df+p+k; make the b,df+p good by doing it as b,b,df+p to give it a better chance of beat a lot of stuff
b,f+p is a little different in that you can't use it for delayed attacks; but abuse this move after every successful dodge and after blocking slow moves
FC,f+p+k is the same in terms of using it to beat certain moves; however, it doesn't have as much range, and of course, doesn't have the high damage possibilities as akira's move

make sure to use his long range moves; b,f+k, b+p, and k are all good moves when goh's not on top of his opponent. if not on top of the opponent, mod the moves by doing a backdash first; especially good with the b+p.

always look to throw, but not TOO much.

unfortunately, you need to work a LOT to use goh well; he's just so lacking in the strike attacks. fun though. i'd say the best options for his delayed attack is to either go for f+p+k,p(40 pts base damage plus oppurtunity to pressure them even more as they get up), or shoulder ram(27 ish pts plus oppurtunity to pressure as they stagger), but he just doesn't really have anything there. f,f+k+g:b+p+g MIGHT be good once in a while, but it's just not quick enough to snag the opponent repeatedly.
