The Basics
Gouken's strenght lies in his fireballs and safe pokes. Use LP fireballs to force opponents to jump unless they want to give you free pressure on block. You can also use MP/HP hadokens to cover the air while poking on the ground with Far LK buffered into Tatsumaki, Far MP, Far HP, Crouch MP and Crouch HK. In a pinch, EX Hadoken can be used to cover both areas, forcing the opponent to temporarly back off unless they're ready to use their anti-projectile moves, allowing Gouken to reposition.
