David again chose a variation played by us five years ago, still believing in the resources of his position. However, I had prepared a poisonous novelty. 8...Ne7

My novelty! Five years ago I played 19.g3 in this position. According to computer 19.g3 gives some advantage to White; however deep analysis shows that Black can get counterplay. 19...Qh4
