To play for a win in the drawn endgame is a good way to lose. If it's equal, just be extra sensitive to how each move effects activity of your pieces and weaknesses/targets. The first rule of endgames in my mind is activity -- more deadly than falling behind in material is falling behind in piece activity (king+ whatever non-pawns are left).
As for weaknesses, for example don't advance any pawns without a good reason because in general each time they move up a rank exposes them more to attack, puts more space behind them for enemy infiltration, etc.
In practice if you can correctly evaluate it as a draw, and just stay active and patient without really doing anything but marking time with your moves, a less experienced opponent is sure to get impatient and give you advantage after advantage and eventually let you win. On the other hand if you yourself aren't too handy with endgames, that's why you practice them -- because in a real game a stronger player will just torture you for 50 moves waiting for a mistake.
Nowadays ive started to realize that the hardest endgames ever is...
EQUAL !!!
well sometimes we can see with equal pieces and position its hard to say draw or win but sometimes we can see there is a possibility for both sides to win but most of it i personally think is draw.
but the point is... what is the main objective of playing and practising equal endgames ? ist to find better way to win ? or to maintain the position for a draw ? if i gotta know what is actually they want, then i have a clear motive when playing and training equal endgames !
Hope everyone can help ! thanks !
