I doubt our choice or recommendation would make a difference in the voting, but we can at least score points for style and character.
Voting at 12 hours is voting too late, which I think we talked about before. I strongly recommend changing that to voting at 8 hours, which would give more than 50% of the voters a chance to see our ideas and recommendations before they have committed.
I am fine with either 15...Qd8 (which many of you support) and 15...N:d5 (which I originally said I preferred). I doubt we can expect a positional mistake from a positional player like Natalia, so leaving the knight on d5 is only going to constrain our position, but if you'd rather vote for Qd8, I'd go along.
Feel free to post here whenever you want, but try to post only ONCE for each move (so one post for 15...Nxd5, one post for 15...Qd8). Please use the EDIT button to update your post and the notes to inform us that you did. You may comment only on your own variations. Comments/questions on another member's variations go in the other topic for the respective move.
