Subject: Crafty question

Does Crafty use fail-soft, fail-hard or a mix of the two?
From the source code I understand that is a mix between the two.
In a fail high it returns the higest score instead of BETA so this is fail-soft.
In the hash table probing it adjusts ALPHA and BETA in a fail-soft manner.
But in a fail low it returns ALPHA so this is a fail-hard.
I'm I correct?

Thank you
