1. I like opening 3. seat a lot and maybe I can talk myself in opening this 1♥ at MP, but I would never open 2. 2. I would finess South 3. Pass 4. If he reopens, he should reopen with 1N IMO. I have never played weak NT so I have no experience with this but pass and 1N look both reasonable. 5. 1♣ then reverse in ♥, this is really obvious. 6. ♦ 7. West 8. Bad luck
