Amazing the stuff you find going through your old games.

4r3/p6R/2p5/5P2/3P2P1/2Pkp3/PP5P/4K3 b - - 0 87

White has just played 44.g3-g4.

Over to you. Black to move. :D

1...Re4 looks like the only reasonable move for Black. White's positoin is quite precarious. Best bet looks like 2.f6 Rxg4 (he daren't try 2...Rf4? as it doesn't work) so 3.Rg7 (the point) Rf4 4.Rg2 and the result should be drawn.

The game must have been interesting to produce that position. Do you have the whole score?

Close, but you missed something. After 44...Re4 45.f6 Rxg4 46.Rg7 Rf4 I believe that White has better than 47.Rg2.

I do, but it's awful. Even for a G60.

Are you going to share it with us?

47.d5! line-clearing to disturb Black's king with checks, after all White has pawns to burn here. 47...cxd5 48.Rd7! (48.f7 only draws) Rxf6 49.Rxd5+ Kc2 50.Ke2 Kxb2 and White should eventually win. 47...Rxf6 48.dxc6 Rxc6 49.Rd7+ Kc2 50.Ke2 Kxb2 51.Rxa7 Rxc3 52.h4 seems clearly won. So I think White still just gets home (evidence to the contrary most welcome), but from four pawns up, it's pretty heavy going.

Check out 49...Ke4 (instead of Kc2) The tempo on the rook doesn't give White the chance to improve the position of his king. If 50.Rd4+ Kf3 and e2 remains denied to the White monarch.

I checked it out. It clearly draws. :clap: So it seems like is drawn after all (which is what I first thought before trying the 47.d5 trick). Four pawns up and nary a win in sight. :eek: Thanks for that.

No worries. Although I was a little over dramatic. Even if the rooks are moved up the board a couple of squares I think Black still draws as Rf2 can be used if White tries Ke2. The key I think is for Black to stay with the e-pawn and not go over to c2.

Yes, the problem for White is that if the Black king stays around the pawn, the Black rook will always have files it can invade to the 7th rank on. Once it gets there White has nothing. The power of one strong pawn in a rook ending is a very important theme. I have recently swindled a few games when one or two pawns down by creating, and focusing obsessively on, one strong pawn. Just have to often make sure the opponent can't sac their rook for it.
