Re: a test position from one of my correspondence game

Post by Eduard »

What is the point of this position? My engine Leptir (with 6 men Syzygy and using nn-335a9b2d8a80.nnue) wants to play Re8 after 2s, and after 5 min the eval looks like this:

3r4/6bk/R6p/3Bp2P/4P1N1/p5P1/5PK1/r7 b - - 0 1

The point is that probably Re8 is the only move for black to draw(I believe stable less than +1 is probably a draw and second best move is bad).

Hello Uri:

There were a few inaccuracies for both sides before move 42 according to my shallow analysis with SF 15.1 with default NNUE net enabled. The last opportunity for black was after 35.- ..., h4:

Thanks for the analysis but
less than +1 advantage by latest stockfish is probably a draw with correct play so I doubt if there was a changing result mistake except move 42.

What is the point of your super dumb question?
The community knows meanwhile that you have have the greatest and best engines :-)
The position was posted so we could show analysis from our engines. I did, no more. But you're just provoking. What a restless, unsatisfied person you are!
