Thanks Michael,

and also thanks for the Positions.

Thanks Herbert,

FYI - you might be interested in following a 250 RR versus latest Stockfish and Komodo in game 100 second/base with 1 second/increment. 1500 games in total ( 6 games per round).

http://talkchess.com/forum/viewtopic.php?t=64169

The opening positions are selected at random for each round. Each round consist of two games, one white and one black , versus each opponent. The opening positions were culled from the CCRL 40/40 database that were slightly unbalance at move 8 , with a centipawn evaluation from 40 to 65. This evaluation range was selected in attempt to reduce the number of draws.

Regards,
Michael

Hi Michael,

Nice Position:
[d]1k6/p3q2r/PpQp1p2/2pPp3/2P1P1p1/2P3P1/2K3P1/5R2 w - - 8 122

What is the source of this game?
Because Movecounter is 122 this can't be a Study !?

I'm sure it's from a game - a great source for me for coding ideas are from fishtest . If I remember correctly , one line of code from this SF patch, slightly modified, helps with positions likes this - which I got from this thread. As I understand , the patch never passed , but I saw no harm in it. This is where I came across the position.

Hi!
Nice postition indeed.
Pity the solution doesn't seem to be a single one, the triangle- maneuvers of King and Rook work in exchange probably, so e.g. 122.Rf5 might transpose

Goldin vs Korzubov, 1980 endgame position is assumed to be engine draw with adequate time control.

But it has nothing to do with the position in question here, has it?

I understand your posting in that way: you think, Michael's one could be drawn too, of course it could, and in most of the output- lines of CorrChess' above no real progress to be seen, yet after about 30 moves I always saw the black g- or a- Pawn fall again and again in Forward- Backward- Forward

This position is originating from Goldin vs Korzubov.
