Nope. I didn't see any refutation for peter's Nd6 line which I have converted into a pgn game:

That line looks like an endgame win for white.

No, Mike, you missed Louis' fortress- line after 26...Nd6 (!) which I had to be shown by him too, my ...Nxd4 (?)- line at first glance was wrong too, thinking then it would hold. (As a matter of fact, I didn't really have one, I just made the same mistake I was smart- alecky against, trusting in an output- line with too little hardware- time and or Forward- Backward.)

Louis showed that 26...Nd6 isn't winning, it leads to a fortress.
Both lines are to be reproduced by backwarding them with enough hardware- time, for the fortress after 26...Nd6 an engine with the fortress detection code from Joseph Ellis (Crystal or Honey X6 FD) is best, especially if you want to see the 0.00 early and keep it in hash backwarding to 26.th.
Yet if anybody has any more questions to the position, ask Louis. It was his game (the one of his SF- installation back in 2014 with Lyudmil) then and it's his thread now.
He brought up all the important lines and he can help best, if anybody is still in doubt here and there in one of these lines.

Can u give the pgn of all the winning lines? I am not getting the results as discussed. hence I will be analyzing deeply now.peter wrote: ↑Tue Oct 15, 2019 6:22 amNo, Mike, you missed Louis' fortress- line after 26...Nd6 (!) which I had to be shown by him too, my ...Nxd4 (?)- line at first glance was wrong too, thinking then it would hold.

I don't have any pgn files. Others do.
Did you save key variations?Spliffjiffer wrote: ↑Mon Oct 14, 2019 8:08 pminteresting position, right?
i had a deep look over 2 weeks on these positions ... with the help of various engines (and it was a hard but fruitful analysis)...
It's not him in particular. People (and not just for this position) get excited about an engine playing a first move and then don't appear to care whether that's really correct, or whether the third move (which is the harder move to find here) is correct.Spliffjiffer wrote: ↑Tue Oct 15, 2019 9:08 pmhehe, but George seems not to be the most accurate analyzer imo (or i am the one who does it wrong)..he claims that after 1.
