Best strategy for keyword attack

[gentl]

Hello guys pls help.
I have a password  (for example MikeStronger!23)
This password doesn't much for current hash but is good for another.
Is any automatic generator  passlist by keyword (MikeStronger)?
Or what the best tactic for attack?

So you know the base word, and you need to append some a special and two numbers?

-r ./rules/hybrid/append_s.rule -r ./rules/hybrid/append_d.rule -r -r ./rules/hybrid/append_d.rule

In this case i can use just mask attack with MikeStronger?a?a?a
But password can be 124MikeStronger!, mikeStronger213@2, mikestronger!44 (just random examples)
I need the way to automatically  create maximal cover of all possible variants. Of course i can use  mask file, make own rules, but may be exist some software to generate wordlist by keyword or something else which can do this task easie

Because masks are executed on GPU, it's probably much faster to just run it as a hybrid (-a 6) or mask attack.

yes....but i still wonder what software can help me to generate maximum coverage of password based on entered keyword.
I found PAC with rulegen.py - but i don't understand results of this analyser
