user7693: How do I get a random position in chessbase 13 software from megadatabase to guess the best move , is this facility available in chessbase software which is availabe is softwares like Chess Hero, Or is there any other software provides such facility?

user7897: Although it isn't chessbase 13, https://www.chessable.com/ is a site, designed to help you learn chess, that works in a similar manner to that described in the question.
The student gets books (usually openings, but there are some endgames) and learns variations - but the default learning pattern is to be shown random positions from those variations, and "guess the move".  (This isn't really a "guess," since you learned the variation, but still...)
The base part of the site is free (and a number of books are free); there are other learning elements that are only available to paid members.  The "library" is growing, including works by several FMs, IMs, and even a few GMs.
TL;DR: It's the same idea as the question, just not on as wide a database.  (One could argue this allows the student to focus on an area; one could also argue it's not as powerful.)
For full disclosure, I have nothing to do with the site itself, though I am a paying member: I've just had such luck with it I'm like a walking billboard.
