More than a dozen, I'm pretty sure...

What do you expect? There are billions. Impossible to count for the time being.

There are less than 70

I mean specific like patrecia mate , anatesja mate , scholar mate etc

How many types of problems are?
or
What's the minimum number of classifications possible to sort every category of problem?

You're spending prime years and talent with a very odd sort of fellows, who, known theory aside, are commited to making a wrong move without exception always. Including Magnus who would certainly play among his peers and betters if it were possible.

Ya, billions or < 70 depending on how you count.

The answer is: the number of capcha's*2. Why? because I say so.
