The situation for this game was that i needed to win to at least share first prize but a draw or loss would see my opponent win outright or at worst jointly. Th opening had worked out wel for me with a small but durable advantage that would be hard to defend against. Still I could not have hoped things to go as smoothly as they did as White was able to increase his advantage with Blacks next move and thereafter it is hard for Black to hold the position.
18...Ne4?
Going into the endgame like this leaves Black with no play and a passive defense all the way from here on in.

Gaining space and creating some disharmony in the Black camp.
23...g5?!
A radical effort to keep things stable on the Kside. The price is the loss of the f5 square forever.
