I have read the book, but it was a while ago now. It's probably the case that at this time of year, the lies that allow a release 2 are very few and far between. i.e. you need grass and not mud.A whole section of Dan Grieve's book is on "golfing IQ", which is selecting the right shot. You're right that he encourages the use of the bounce for a release 2, but the golfing IQ section will say something like, if you're on wet ground with a bare lie, don't choose release 2. It's not just about technique
Personally, I've only really read the technique chapters and that's why I think I hit so many fats at the moment!
What I like about his approach is that it's all very logical; one thing follows on from another. For example, he says that for release 2, you want to use the middle of the bounce. The natural way to want to do this is to hit the ball later in the arc, and sure enough when you read on, in the setup for a release 2 you have the ball further forward vs a release 1. As you've done in your OP, you might think, well I'm going to end up fatting it on the wrong type of lie, and you'd be right, and he goes on to talk about that as well. You can almost work out what he's going to say next from the information you've already been given.
In winter, he advocates playing a release 1 (like a bump and run) unless the situation is perfect. The different releases are just starting points and the whole aim is to get you thinking about how the club, turf/ground and ball are going to interact to build up the shot you want to pull off -- and the one that looks best from behind the ball in terms of desired flight and landing area might not necessarily be on because of the lie, for example.
I was never intending to say Grieve's stuff doesn't work, I enjoy his content and think he's great. I just think maybe for me, thinking about the bounce and actively trying to use it is unhelpful. I'm using wedges that have plenty of bounce on them, so I probably don't need to think about it that much.
I think the assessing the lie part is quite difficult sometimes. It may look like it's sitting nicely but there's just mud underneath, or there might be more grass that it looks. If I'm on fairway or fringe I just find the hybrid bump the best shot for me to be honest - after having my lesson, you kind of really want to chip 'properly' for a while don't you? Then eventually realise the results were still better with the low bump so you should never have stopped doing that.
