No squared deadzone???

[Donatello]

i see pro players use no squared deadzone what is that .
do they mean circle deadzone or cross deadzone or squared deadzone?

Most professional players use default, aka "cross". As in, they don't touch the Steam settings or use the 3rd party program "Durazno" to change their deadzone shape. Technically, it's not a deadzone but an input border, improperly named "deadzone". A deadzone is technically the input away from the center that is "dead" so that the controller doesn't register input all the time, since all analog sticks have a "drift" away from their centers, even if only slightly.
