9...Nc6 is not possible, you mean perhaps 9...Nf6

We usually see on Talkchess positions with a best move to find, here's one with no best move to find. Is this it? If white blundered its advantage somewhere I wonder where it was, or if in the future all lines will look like this...
A question. What's the point of excluding ...Nf6 from the search?

Re: I accidentally a position o_O

Post by Ovyron »

It speeds up the analysis for alternative moves (if one is better than Nf6 it'll "jump out" much faster than if Nf6 is included.) Note Nf6 is the mainline (strictly better for non-transposing variations) and I had already analyzed it.

The reason this was shared is because I don't intend to ever play 9...Be7!? in that position so it can't hurt me, and perhaps someone finds it interesting. But I was surprised that it may be enough to hold the draw with ease; in my experience Nxc6 in the Sicilian leads mostly to nothing.
