I ran a bunch of engines over this position, and they finally all agreed on Qc7! over Rc6, but SmarThink 1.8 (may I didn't let it ponder long enough).

Some like Hiarcs prefer Rc6 for a while, but after a long think (one hour on my core i7) switch back to Qc7.

Yes, Rc6 was nice (I was thinking that too), but apparently it is not the best. :-(

We tend to prefer the beautiful over the pragmatic.

I guess we all enjoy a move that takes our breath away.

I think against humans the more subtle move would be better because the queen move also has obvious replies and ends in a draw at best as well.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
