107 moves leads to a draw :)

Hello,

There seems to be quite a bit of difficulty in finding a clean win in the exchange up endgame. One reason is that because of the reduced number of pawns, giving back the exchange to win a pawn doesn,t seem to work.

    Certainly to find an easier win, white could look at why he allowed his passed a pawn to drop.   A very quick look suggests that he was in too much of a hurry to exchange queens, and didnot notice Nc5 was coming in time.

Bye John S 

 That's true, but einstein is a good player!  No good player would let a draw occur...

yikes

No intend to bring you down for not winning. With over 100 moves it is easy to miss one or two possible combinations, though there is a pretty easy win after move 89:

Ironically, this sollution also ends in 107 moves:)

If I remember right I did consider RxN in hopes to make my passed pawn count but instead on 91...Kg7 he plays 91...Kh7.  If he plays 91...Kg7 then that would give me a win.  :)  But 91...Kh7 leads to a draw with carefull play by black.  :)

Oh, it looks like my diagram has a display error.  :)  It played out the moves I wanted to display but the starting position is suppose to look like the one in MagterGnu's diagram.  :)  That means disregard all of blacks queenside pieces lol.  :)

Yeah, you're right. 

An advice when you have so few pieces to work with is to press the "clear board"-button directly and remove all pieces from the board.

who did you play

isn't 81. RxN winning? because after 81...KxR 82 Ke4  Kg6  83 Ke5 and white wins.  Just a thought =)

. What did people think of  Gonnosuke's analysis earlier. It boils down to the R+N v 2N endgame being won, because white is an exchange up.  This is probably right but looks pretty hard to prove it against the best black defences. For example, instead of 71...Nc5 allowing exchange of d and h-pawns probably winning, black can play 71...Kg6 maybe white can continue with Kf3 -e4 then?, still looks like hard work though.

I would say Gonnosuke's line had some potential for white.  :)  It would be very difficult for white to find a winning line being up only in the exchange of a rook for a knight.

Wow... This is a thread that truly has stood the test of time...I applaud you, Einstein, for making a thread that last, and for a brilliant game that I myself got quite a bit from.

Good game, and congrats on drawing a tough opponent. And just for the record, anybody trying to offer improvements, don't look past move 74, as tablebases will agree that the position was drawn.
