Lomonosov 7-piece query

Post by David Robertson » Thu Feb 08, 2018 4:57 pm

If anyone has ready access to the Lomonosov 7-piece tablebase, I'd appreciate help with the following position:

White Kd3, Nf3, b3
Black Kd5, Bc5, b5, f4

Either to move (I doubt it's material)

The position arose last night in a league game when, after extensive efforts to make progress, Black offered the draw. But is it ever winnable for B? I'm not sure, though I suspect it's drawn. Houdini 4 isn't a great deal of help. So over to Lomonosov

Draw. White to play can even play 1.b4 and if Bxb4 2.Nd4

Thanks indeed.

I wouldn't worry too much about 1. b4 since the B (c5) could be pretty much anywhere. In fact the game ended with a repetition: 1...Bf2; 2 Ke2 Be3; 3 Kd3

And I was White v. one of my club's highly promising 15 year olds. We'll use the Lomonosov verdict to save some time when coaching tomorrow night

Yeah. But I don't have. I checked the website; signed up; but no PC access. I think I've got Lomonosov on disk somewhere, but have been too bone-idle to load it. As per usual :roll:

I've got the app on my PC via the free Bluestacks Android Emulator. Works great.

Not at 100TB you haven't. That's over 23,000 DVDs.
