Re: Hard Puzzle for July

OK. This is my problem. Thanks. Because this version is much harder for engines on my computer. :) Is it, indeed? Didn't notice much difference as for my trials with engines, yet to say I this time didn't have to let them try as much as before ponderin on their own alone, but just started with alre...

Re: Hard Puzzle for July

Do I have to look for new DTM now in the 2.g8Q- line? :twisted: Yes. We were quite not sure if Black still wins here. Don't know, why you doubt the position with White's King displaced so little only, not to be won after the much shorter way to next pawn- or capture- move in 2.g8Q- line. The longer...

Re: Hard Puzzle for July

BTW, a middle school boy solved Mihai Neghina's puzzle in just a few minutes. That's another story. About mine? I spent a week in composing it, and three days checking it with my friend F and his engines(thx for his help!), the 2.g8Q line is quite difficult for humans. In fact I'm lucky, we didn't ...

Re: Polish users cut off from TalkChess

Just install opera for windows on your pc. It has a built in vpn. +1 Worked for me. Not for me! Previously, unread posts were marked red, reads are black. If I now read red marked posts and then go back to read a new thread, I am logged out. After logging in again, the already read thread is marked...

Re: Hard Puzzle for July

I did't know anything about chess compositions about one year ago. My friend K taught me, and Pafifi advised me to post my compositions on TalkChess. Thank you for enjoying my puzzles! About this puzzle: I got inspiration from viewtopic.php?f=2&t=59727&start=10#p666653 . It is a Black to win proble...

Re: Hard Puzzle for July

But 58# is also over 50 move rule :cry: :twisted: Pity, but yes. After your main line with 48...Ba5 ff at 52.Bb3 instead of a7 is drawn by 50, in your line in braces 48...Kb8, from there onward like in your .pgn, with 55.Bb3 50 moves- boundary it reached as well. But it's fun to go on and on trying...

Re: Hard Puzzle for July

Have a look: But rather at this one, the one before once again was buggy, 73.Bb3 shouldn't be answered by Kxa6?! but by Ka8 of course, that ends up <100: [Event "?"] [Site "?"] [Date "2021.07.28"] [Round "?"] [White "Hobacle"] [Black "Juli"] [Result "0-1"] [Annotator "Martan,Peter"] [SetUp "1"] [FE...

Re: Hard Puzzle for July

Engine didn't help me from 2...Qg5+ to 90.g8N at all. Have you considered a question, how can Ottó Bláthy find the exact DTMs of his puzzles 140 years ago? And this puzzle is #106 undoubtedly. Well that's the question, and it wasn't me, who did raise it to this importance, but it's one of thematic ...
