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.

If it indeed draws vs best play, and it was from an even position, then Nd5 is indeed a great move.
Indeed, it clears lines for both bishops, facing the king, which is quite a wonderful thing.
Ah! You mean that Ne2 draws. Not Nd5 knight sac.

Re: Tal's bold and reckless 16. Nd5

Yes, Ne2 draws with best play. Nd5 ought to lose. But I guess because Tal did it, it scared the ever-loving piss out of his opponent and he blundered.
It is a complex position, and I think at the time it might have been considered unclear.
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.

Gave his opponent too much work to do
