Re: testposition from the topboard of the candidates

I have this line at +4.09 which is much better than any of the lines you gave. It doesn't prove the OP is right, but it also doesn't support the idea that the OP is wrong either. I trust your analysis. If you have a chance, please analyze 23. Rxb6. My guess is you'll be well over 4.09, without havi...

Re: testposition from the topboard of the candidates

If you didn´t find an improvement in this moves it is proven that 23.f4 !! is best. As I said in my very first reply, White already had a won position before move 23. A variety of twenty-third moves by White maintain the win. Previously, you suggested that "best" meant "the shortest way to a full p...

Re: testposition from the topboard of the candidates

The moves are shown by stockfish are not convincing. For example 24.Rxb6? So i have two questions: A) What is the defence of the machine against 24.g4 !? with the plan of Ng3 and pawn f5? B) How improves the machine the black play after MVL's 24.Rfb1? For (B), it seems that 26...Kf7 is weak. Lc0 (3...

Re: testposition from the topboard of the candidates

Ok, this is a individual opinion for this position. But what is the value of this opinion? We have no access to the opinion of Magnus Carlsen and Alpha Zero. Lc0 agrees with Stockfish that f4 is not one of the top three moves: Nodes: 2.5M, N/s: 5.6k, Time: 7m 24s 83.6% Rxb6 Nxb6 Ra1 Kd7 Bc1 Nc8 Rb1...
