From the Crowthorne Vaults – Part 3

Colin has also been rummaging around the vaults, and he has found this position. it arose in his game against Sarah Hegarty in a match Crowthorne v Sandhurst, played in 2011.

White was rather outplayed in the opening, and is an exchange and pawn down. He does have some compensation in that Black is missing her fianchettoed bishop and the knights are rather offside. Even so, Black would have been better had she not played 20 …fxe4 on here previous move (much better was 20 …Nf6 although this was not an obvious move to find).

How can white play to save the game?
