Experienced and knowledgeable tournament players generally know when methods they use are unusual. Blakjak tells us that there are many poor players who don't understand basic bidding theory, who reverse accidentally and have little idea whether their methods (or lack of them) is unusual or not. I think we should not concern ourselves with the latter group here. I play in the same geographical area as Blakjak and in some of the same games. Much of the bridge is weird and wonderful and I would attach no great significance to any alert or lack of it in these kinds of game. It would certainly not occur to me to claim damage in such an auction.
Cyberyeti tells us that he has methods which allow his partnership to force in a situation where I would bid say 1♣ Pass 1♠ Pass 2♥ and expect partner to keep bidding. Cyberyeti knows his methods are unusual and I would expect him to alert. It's not very obvious how damage might occur in such a sequence so I'd need a lot of convincing before I'd even think about adjusting, but if I played 2♥ here as NF, I'd want to tell my opponents and if my opponents played this I'd like them to tell me because frankly it would not occur to me that this was NF
My 1
♦-1
♠-2
♥ still shows a very good hand, just the absolute monsters are filtered out, so this means my 2
♥ is pretty much the same as it would be for somebody playing an acol 2
♦ so what my hand is should be covered by general bridge knowledge in the UK. 2
♥ is "forcing" but if partner has improved the contract by bidding 1
♠ with QJ10xx, xxx, void, xxxxx then he's entitled to pass if he chooses, it's probably a better spot than 1
♦. As such we don't alert this, but do alert the 2N GF unbalanced rebid.
