It's a question we've discussed before: is "partner has UI, which limits his actions to unsuggested LAs, and he's picked this one. Am I allowed to use the fact that I've given him this UI and what limitations he would have in my further bidding?"
In other words: "partner's only allowed to bid 6♥ if it's a '100% call'. Partner bid 6♥, knowing we're off the trump Q - if it's a 100% call, he either "has" the trump Q, or isn't off one key and the Q, otherwise it will be rolled back (and partner is actively ethical and knowledgable). The chance partner "has" the trump Q is very low. Can I bid 7, knowing we have 6-of-the-6?"
Similar cases: "I tank-invited because I'm almost strong enough. Partner went to game, and I know that has to be a 100% call opposite any random invitation. Can I use that knowledge to look for 6?" and "I said 2♦ was a transfer because I forgot we don't play systems on over double. Now that I remember, can I use the fact that partner does *not* have enough hearts to float the 2♥ 'rescue' (and enough diamonds, and no second suit to have an alternative to 3♦) after they compete over 3♦?"
All the I - that I passed UI, what the LAs would likely be, the fact that partner is ethical enough that the call he made isn't going to be flagged - is, I believe, Authorized. But allowing this seems - wrong.
