Hi Abdulaziz.  Must have been painful to draw this game considering it was a won endgame for you.  It looks to me that starting on move 76 you just started moving pieces without a clear goal.  Endgame is a very precise part of the game.  If you didn't have a Knight at move 76, the game is a draw because the black King goes to corner.  That is black's plan.  But you do have a Knight and it can get the black king out of the corner.  Thus a plan should have been to go protect the pawn with your king, and then position your Knight to get the black king out of the corner.  A book recomended is Endgame Manual by Mark Dvoretsky 3rd edition.  Buy it and join our study group!

It's also page 116 of Silman's book. It's a win if the pawn is on the 6th rank, draw on the 7th. You just have to watch out for stalemate and make sure the knight can check on the queening square.

I know you might be short on time, but it's worth investing a few seconds to work out the accurate moves. After move 76 it's just a matter of technique.

Hi, I did not have time. I had to end the game in 1/2 Minute.

Any way, I did not interested in winning the game.

Thank you very mutch all.
