I am not sure if I am going now to answer what you were asking, but: settings - > live chess - > and there should somewhere be analysis after game or something like this.However after live game, you should be able to click on analysis button and it should just works...
Learn -> Analysis and then you get the evaluation bar for the position you set up on the board. If you tick Show lines, you can see the lines, too. The after game analysis has more depth, though, but the analysis board should be fine for most positions.
For openings Learn -> Explorer lets you go through moves that master level players have made in a given position. They don't contain the evaluation of the position by an engine, but if some move has been played often (and it isn't losing all the time), it is an indication that it is a solid move.
