Line 2 of the Sicilian Defense Najdorf Variation page 248?

I see what you mean. Column 2 (not line 2) on p. 248 (not 249). Yes, I believe you have it right. Move 10 shouldn't be g5 (illegal), it should be blank, meaning that columns 2-3 are all about 10 0-0-0. Which makes sense, since that's virtually the only move ever played there, and the only move that makes sense.

I don't have MCO handy.
Is this the line?
No, it's a line in the English attack. Not sure why the third poster was suggesting that one game out of the hundreds of thousands of Najdorf games out there...

I took a main line with moves 10-12 g2-g4-g5.
The error probably stems from the conversion of the descriptive notation to the algebraic notation. P-N4 for black can mean b5 as well as g5.
I looked at it further and g5 from column 2 should be in Column 4. Column 4 is missing the 10th move for white and it works with g5 since g4 is played on the 9 move. Further confirmed because there are no connecting dots from column 1 and 2 on the 10th move for white. g5 on column 2 is wrong. Looks like they messed up the formatting when editing/tabulating that table
