All book to move 10 and not the sort of thing I would be happy to play over the board but I do get my beloved 3:2 queenside majority. But Alan is just too good for me.
After 14.g4 with no counter in the center I needed to play a5 and get my plan going.
At move 16.Bxc3 was correct but I get the captures wrong and end up after 18.b3 with very embarrassed Ns.
