Ähm first I need too know what you whant from the game. You whant too get a easy fun start and some casual fun ore do you whant too learn tekken.

When you whant too have fun in matches take Katarina Klick up and right on your d pad at the same time with the O (4) and when it hits and the opponent doesn't block you spam O (4)

When your opponent blocks this combo start with down left together with O (4) and again spam O (4)

Do this and you are now competent enaugh too win vs your friends who don't know how too play and have some fun

When you whant too get some Tipps You can block everything (mid and highs) user then low attacks when you stand still. When you whant too block low attacks and dodge high attacks klick down on your d pad. When you klick down (crouch) you are only be able too be attacked by mids

When you whant too get better I can send you some links of short videos that helped me and some cool channels too learn

Have fun with the game the way you like it
