Today's Position

White to move

This position is not among the five that I considered today from Thomas Engqvist, 300 Most Important Chess Positions (2018), which I am working through at the rate of five positions per day. The position does come from a game from which Engqvist extracted three positions, but it was this moment in several games that captured most of my time this morning.

This position seems to have arisen for the first time in Gelfand,B. -- Karpov,A., Sanghi Nagar 1995 and at least twice more that year.

Gelfand played 9.Nd2 and lost after a long struggle. In Anatoly Karpov, How to Play the English Opening (2007), it references 9.Ne1, first played in Gulko,B. -- Sadler,M., Lucerne 1997 as an improvement for White (47). Nonetheless, ChessBase Mega has two White wins, two draws, and four Black wins after 9.Ne1. One of the draws is Engqvist's source game.

After 9.Nd2, White has three wins, a draw, and two losses. Why is 9.Ne1 an improvement?
