Smart Brutforce?

Hey, is there anyway that I am able to modify tHE attack in that the variation completely skips over any possible combination containing recurring alpha numeric char. I.E "aajfajfwja" or "bbbmagic" etc... 
Also is anyone aware of a website on which I can play with these variables and get an ETA or simply amount of possible combinations.

You can use PACK to match a specific password policy or play around with hashcat's mask attack and the -t argument. Unfortunately with -t it's not possible to later resume an attack by using a higher threshold.
