Not one of mine, but here is the current #2 on this site (will probably be #1 before too long) losing to unspectacular but solid play by someone rated around 1800: Game 4143531.
Incidentally, this is the position after White's 45th move:
This is a very simple draw, any OTB player rated over 2000 could draw this for Black without any effort at all. I'm astonished that Altern8 doesn't know his basic rook and pawn endings.

Even I know the Philidor position.
In Silmans endgame manual he grades this knowledge as 'class C' (players 1400 - 1599). Seem wierd that someone can get 2250+ without being aware, but not impossible obviously.

Doesn't this give him the exception to the usual Philidor? Can he not simply block the barrage of Rook checks characteristic of this drawing motif, by Rd4! ?
Yes, surely he can. A normal Philidor is about the defending rook getting to the 6th in this position, preventing whites King stepping forward. Advancing the pawn is fruitless because black plays Rh1, with a view to drawing by a barrage of checks which white cannot avoid.
But in the given position, white can block that barrage with Rd4. Where does black go from there? He cannot exchange rooks, as does this not lead to a simple K+P vs K endgame? If he doesn't exchange rooks whites king steps forward does it not?
Originally posted by Policestateblack only plays his rook to the cheking rank after white advances his pawn, if he doesnt do so he will just keep it on the 3rd (6th in this case) rank. After white moves the pawn up his king can't hide from the checks behind the pawn and is so defenceless. If he interposes with his rook black just swaps them of and moves his king to the field in front of the pawn. Then it is just simply an easy king and pawn draw, just moving the king backwards in a straight line when black looses the oposition and it will be impossible for white to queen
Ahh - is it because after the exchange of rooks, white actually can't get his King infront of his pawn, so black draws the resulting K+P vs K?

Originally posted by orion25Purely as a matter of interest, and I don't mean to imply anything by this, but is anyone able to test whether a strong engine, say Fritz 10 or 11, can draw the black side of this position if it hasn't got the endgame tablebases installed?

I agree with the different skill sets idea. I have a friend in Florida (US) who is an 1800 player +/- (150 or so ECF, I think), but he is something like 2300+ in international correspondence chess, even playing on the US team. In OTB chess he just blunders occasionally, whereas in CC he is much more careful, and he definitely does not cheat.
Sometimes I think we can get too caught up in the ratings, especially when a person hasn't played that many games. They are certainly an accurate indicator of playing strength under set parameters, but they only partially indicate chess knowledge.
In one of Karpov's biographies, he talks about his trainer, GM Semyon Furman. Furman used to be able to predict Karpov's moves with something like 99% accuracy. One time in the press room, the other GMS were mystified, and Korchnoi asked him "If you can predict Karpov's moves so accurately, while don't you play these moves in your own games?" Furman's only answer was something like a shrug and "that's not how I play".
