1) It is NOT what you do when you play with the misinformation, it is what you would do when you have the right information.
2) Misplaying 2♥ is not an 'extremely serious error unrelated to the infraction'. North is quite likely to just bid 1♥ when they know that 1♦ is negative - in which case the meaning of 2♥ is moot.
I completely disagree, I think they're more likely to bid 2♥ than 1♥ if they know it's negative, as if it's not, you're much less likely to have game on so don't need to show your balanced 11 opposite what is probably another 11 or 12 and can just bid 1♥.
Hence I don't think it's related to the infraction. The play is 2 tricks suboptimal on most if not all defences, and I'm really struggling to see how you go off, but I know serious error requires ridiculous levels of idiocy (and IMO requires too much idiocy, as people who've played seriously badly and got a bad score because of that still get redress and apparently would have played 3N like a magician (not that you need to here), despite the fact that they played 2♥ like an idiot).
