Mine Clearing and lanes?

[Philippe]

The strength of the mines is not mentioned in the passage I quoted, so I don't think that it's relevant to the situation.

I think it is sometimes helpful not to think of the user's manual as the rules themselves but as merely descriptive of the rules. The manual's merely a guide (albeit a pretty accurate one) rather than chapter and verse. There are a few things that aren't in it yet, but they will get there eventually.
