Disclosure obviously depends on how frequently you upgrade. If 10% of your 1NT openers are upgrades, then clearly this should be announced. 5% too, It seems to me. I don't know where the cutoff is, but there should really be one.
On this we could probably agree.
There are tricky areas, at least partly due to varying levels of commitment to the game. I mentioned elsewhere that with a minimum 2=3=4=4 hand I open 1
♦ but one of my partners would open it 1
♣, and neither of us are willing to change. Fortunately, we do not have to check a box on the standard acbl cc as to which we do. If the opponents ask about my partner's 1m opening, I would be happy to tell them. I don't think I have ever been asked. Similarly, I have sometimes played in the Walsh style where, supposedly at least, I would jump over KQJTxx of diamonds (unless holding gf values) to respond 1
♥ on 8642. It seems reasonable to alert such a style. But Kit Woolsey, in his book Matchpoints, recommend that when partner opens 1
♣ you sometimes jump over diamonds to bid a major and sometimes not. I still have the book around someplace,I have not looked it up, but as I recall part of his thinking is that if the four card major is strong enough that you don't mind being raised on three then skipping over diamonds is fine, but if the four cards are shaggy and you have a perfectly fine diamond suit then bid that. I regard this as practical bidding, not a conventional understanding.
I am always more that willing to explain our style to the extent that I know what it is. Often the extent is not very extensive.
Various things can defeat the best of intentions. Some years back I was playing in the "Unit Game". Not the Nationals but a decent game, Steve Robinson plays in it for example. I had agreed to play in the Walsh style, I opened 1
♣, partner bid 1
♥ and I alerted. I was asked to explain and I did, or so I thought. I explained that partner would very often pass over even a very strong diamond suit to bid any four card heart suit. I was asked for more detail and I explained that partner, holding four hearts and long diamonds, would bid the diamonds only in the case that his hand was strong enough to make a game forcing reverse into hearts if my rebid over 1
♦ was 1NT. Sill some confusion, but eventually we played the hands. After the round, as we were heading for the next table, I caught part of the conversation from the table we just finished: "He said his partner would bid 1
♥ with four hearts and long diamonds but he did bid 1
♥ and he didn't have long diamonds."
