pattern mask

[jokocc]

hello, I'm newbie in hashcat. im trying to crack a 12 character password. i know that a component in the password is a word 'g00se'. but what i don't know is the position of the word inside the password (maybe on the beginning, middle, or the end). 

how can i make the mask appropriate? 
since it's only 7 more (alpha numeric with special chacter) digits left to crack.

any help would be appreciated, thanks.
