I'm enjoying my study as a relative noob into chess (1000 rapid in Lichess and on Chess.com in the last month or so) and am getting very interested in openings.

Is there a relative root tree that you can use to approach openings e.g. if x is played, the optimal is to play y? (that obviously assumes you have the knowledge to play them as well). With obvious cut across moves to transpose?

E.g. my thoughts made me think of this clip from Person of Interest https://youtu.be/ttRuzAaAURA & it how it tracks an opening in chess.com e.g. against games on the database and how that adjusts the percentages.

Easiest examples of switching or transposing (I think that is the correct term) I could think of as a noob:

Set out to play the Vienna; black goes 2.Nc6 and then you go 3.f4 and play the Gambit instead of going 3.Bc4 (not sure if that works out better on an engine but I'm thinking as an example).

Other one I could think of - open with e4 trying to play the Vienna again, get c6 back & then play 2.d4 and switch to a Smith Morra (again not sure if that is better than 2.Nc3).

I just wondered if there was some kind of approach or path for transposing or switching?

Thanks in advance for any advice or suggestions.

I think what you are looking for is something like




In both cases, you can build opening move trees (either for White or for Black - you train/drill one side per tree) by picking moves for any given position and the site will automatically handle transpositions for you if you reach matching positions (one branch will then point to the other).

If you specifically look for a tree with "optimal y's": Sorry, but that is still up to a lot of debate.
