A game from my current running tournament Zzzz_0_1,including 27 engines and me,2 games against each other,756 games in total....

{512MB, RybkaIII.ctg, Fallen Angel} 1. e4 c5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5.

[D]8/pbr4k/1p2p1pp/2p5/2PnpP2/PP4P1/5BBP/4R1K1 w - - 2 32
I've been waiting for this move and I knew that the machine was going down the road of defeat....
32. Bxd4 cxd4 33. Bxe4 Bxe4 34. Rxe4 Rd7 35. Kf2 d3 36. Ke1 d2+ 37. Kd1 h5
38. Rxe6 Kg7 39. Re2 Rd3 40. Rxd2 Rxb3 41. Rd7+ Kh6 42. Rxa7 Rb1+ 43. Kc2 Rh1

[D]8/2P5/1K4pk/8/1R3P1p/2r5/8/8 w - - 1 55
And now,one of the most stupid moves I've ever made in my life playing the endgame like a real patzer
Of course the winning move is not easy to find ,more over when you are under time pressure....
55. Kb7?? h3 56. c8=Q Rxc8
57. Kxc8 g5 58. fxg5+ Kxg5 59. Kd7 h2 60. Rb1 Kh4 61. Ke6 Kh3 62. Rb3+ Kg2 63.
Rb2+ Kh3 64. Rb3+ Kg2 1/2-1/2
Now,can you spot the right move within let's say 15-20 seconds
I assume most of the 2400+ Elo can find it easy,no
Cheers,
Dr.D

Re: How to waste a won endgame position....
At first sight I will say build a bridge with Rb5 intending Rc5.

Re: How to waste a won endgame position....
In a blitz game I would have played Kb7 too I'm afraid.
Knowing that's not the move, my first thought was to push
f5. Then I saw Rb5-c5, that's indeed the easiest way. I calculated f5 out of curiosity a bit and it seems to work as well, but I'm not sure.

Re: How to waste a won endgame position....
Don't lament, it's an easy mistake to make especially in time trouble as Kb7 would usually be enough.Dr.Wael Deeb wrote:Exactly what I did under the time pressure....unfortunatelyplayjunior wrote:In a blitz game I would have played Kb7 too I'm afraid.Knowing that's not the move, my first thought was to push

In this case Rb5! with the idea Rc5 and you would ensure the win.

Re: How to waste a won endgame position....
It looks like there are (at least) three moves that win. We all agree that the Rb5-Rc5 plan works. My first thought was f5, which also works. After 1.f5...
1...h3 2.Rh4+ Kg5 3.Rxh3 Rxh3 4.c8=Q gxf5 and White has Mate in 48, although it will probably be VERY difficult. I know *I* couldn't win it.
or 1...gxf5 2.Rxh4+ Kg5 3.Rh8 g4 4.c8=Q Rxc8 5.Rxc8 and White has a Mate in 17.
or 1...gxf5 2.Rxh4+ Kg7 3.Rd4 (any, best might be Kf7, avoiding Kf6? Rd6+) 4.Rd8 Ke6 5.c8=Q and White wins.
But I think that 1.Ra4?! also wins, with the thought of 2.Ra8. CM9_R1 found this move after 16 seconds on my P4-2.4. 1...h3 and 1...g5 both lose, and 1...Rc1 appears to be best. But after 2.Ra8 I can't find a way for Black to draw. Can anybody else?
I think even 1.Rb1 will work, with the idea of 2.Rh1.
But, yeah, honestly, I would definitely have played Kb7 OTB.
