Here will be links to points within the system notes which are new or require discussion. After the non-poster — Gábor if John posted, John if Gábor posted — has read the discussion point, he will make a notation here to that effect along with a response.
I agree with those. I would also add that the second relay cannot be declarer's first suit. E.g.
1
-1N / 2
-2 is just a non-invitational 3 card preference to , and at most a singleton . (The hand cannot be invitational, as in that case there was a 5 card minor to bid – although this logic could be applied to the non-passed hand, too…)
1
-1N-2
-2 is also not second relay, it may have 4, did not want to bypass the 5-3 or 5-4 fit in a major.

Those points are exactly why I said a new suit is a relay.
Ah, ok. Looks like I needed to have it spelled out for me…
