Positions you can't avoid

One good approach to building a repertoire could be to consider the positions that you can't avoid. This works particularly for the busy or the lazy people. And for the human beings, because, unless you are Kasparov, I suppose that it's just impossible to deal with all the most critical variations.

I have an example in mind which hopefully will make it clear. For an 'e4' player ready to play the sicilian without all the Bb5 or c3 stuff, the following position seems difficult to avoid, when playing against the accelerated dragon:

We have now reached a position of the 'normal' dragon which is not considered as the sharpest but I think that it's nevertheless a very interesting position.

Of course, Black could deviate with, say 7. ... Qa5 (even though I was recently told that this move is dubious (?!)). If things were so easy, chess would already have been solved.

White could also deviate earlier.

But for a player who has not so much time for the theory, wouldn't it make sense to have a good look at this position? It could also come from a normal dragon, i.e. there are at least 2 ways for the e4-player to reach this position. Going further, wouldn't it be reasonable to be ready for this position before studying any other complicated variation of the dragon or of the accelerated dragon?

Study one position and get an answer for 2 openings!

Sounds great!

I guess that I am trying to find a way to look at transpositions as a positive thing

Do you have other examples like this one which you would like to share?

Transposition to Semi-Tarrasch from Sicilian o.o? I know theres the transposition to Accl Dragon from KID but how does this happen?
