Greek Gift Sacrifice

I'm trying to work on a study, can any tell me about any mistakes on it?

First game I played here, I zapped somebody with it. This win inflated my rating to well above my actual level of competence.

@Blundergus That's not a greek gift sacrifice. That's you attacking h7 then mate in one, both of which your opponent missed.

I would put chapter 6 as chapter 2 because it is very easy and what weaker player should solve first

In chapter 4 I think there is something easier. Instead of playing h4 we can play Qh5. We have a deadly discover check with the queen and the bishop in h7.

Best move order is Bishop take bishop, Bg6 + / Bh6 / Bxh6 / gxh6 / Qxh6 mate in one then

Mistakes from which side?

What #4 @Slugy says

Put chapter 6 at the start, correct Qh5 insted of h4 for chapter 4.

Chapter 5 contains some mistakes and is unnecessarily long. No need to show the whole variation until checkmate, the point is that you are winning.

Perhaps allow for engine evaluation once the chapter has been completed. It's favourable to browse freely.

Overall a nice study!

I don't know how to change analysis privileges at the end.

In the final move in lesson 6, I think Qe1 works as well as Rde1.
