Tekken 6Follow

Blocking in Tekken is the same as it is in Street Fighter where you hold back to block mid and high range attacks and down/back to block low blows. It's odd because Soul Calibur, the other Namco fighter has a guard button.

I always found it easier to sidestep in Tekken then try to block

This is definitely how it works, but mind you not all attacks can be blocked. You can usually tell which attacks these are when it involves them doing some sort of long wind up and a lot of glowing aura or flames start to surround them while charging up. These moves are more often then not incredibly slow though so it gives you plenty of time to hit your opponent mid move or to just side step. Also, throws can't be blocked but they can be stopped or sometimes even reversed if you input the same throw as your enemy when they grab you.

I've been playing Tekken for a while now so yeah, if you have any questions feel free to ask.

I haven't played 6, but don't stop practicing until you've got two of King's 10 strings & no less than one of his chain throws down.

It could be that you got hit by the initial attack, which causes you to be stunned momentarily. You usually can't block in the middle of someones combo if one of the hits in the combo connected before hand unless the combo in general is slow.

That's good to hear. Not that I've played Tekken seriously since 4, but I remember being SO pissed off at my friend's brother. He'd only play Hwoarang, and that combo was nothing but trouble. I finally just played Practice mode against Hwoarang as King until I could counter the combo with a throw.

Although I remember beating Hwoarang with Dr. Bosconovitch once or twice. God, that was embarrassing for him... (If no one remembers, Dr. B was a hidden character in Tekken 3, unlocked by beating the Tekken Force minigame. He was this drunk old scientist who could barely stand up. He started each round laying on the ground. He had some nasty ground moves, and if you could get him standing up he was vicious, but when you have to go to lengths just to get your character to stand up...)
