Endgames 1

It is probably true that endgames are the weakest part of amateur chess.

I have made a mistake here and am a piece down....

25. Rf2

...but I always play on a couple of moves in blitz just in case, and here, I realise that White does not know what to do.

In endgames, not only do you have to play to defend, but you must always keep checkmate in mind when many pieces are on the board.

Thus, 24 moves later, despite White still being ahead greatly and after barely an attacking threat, he does not spot the impending mate at all...

48...Re1 

...and falls to a rook and lowly pawn.

Checkmate

Its only blitz....
