Once in the study revision process, two scenarios are possible: the next move is either straightforward or has multiple nodes.

The next move has only one possibility on the nodes tree.

For example, in this move tree after Qb6, only Nf3 is possible.

The goal is to guess the move. If you’re having trouble, you can ask for a hint that will tell you which piece to move. You can also request the solution to find out which piece to move and where to place it.

The next move has several possibilities on the nodes tree.

For example, in this move tree after Qb6, several moves are possible : Nf3, Bd3, Qb3

If multiple moves are defined as possible next moves in the move tree, we need to choose which line to explore, as it’s impossible to guess the move in this scenario.
