### Re: Hard-Talkchess-2019 set

The ep notation d6 is spurious here, since it has no affect on the position.
r1b1k1r1/1p2np1p/p1n1pQp1/3p4/3NPP2/P2RB3/2PK2PP/q4B1R w q d6
I prefer:
r1b1k1r1/1p2np1p/p1n1pQp1/3p4/3NPP2/P2RB3/2PK2PP/q4B1R w q -

I know the EPD standard says always set the flag when the pawn moves 2 spaces. But it doubles analysis when you have two identical positions, one with an ep flag and one without and both identical in possible move choices.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Thanks for the correction !
Now, I'm removing 2 positions :

Code: Select all

rn3rq1/p5k1/2p2bp1/1p4p1/8/2P1B1PQ/5PK1/3R3R <- Rd6 and c4 seems both winning.
2k5/2p5/1q1p4/pPpPp1pp/N1P1Pp2/P4PbP/KQ4P1/8 w - - am Nxb6+?; <- I don't see how to win.
And I'm adding 6 older positions, sometimes easy and sometimes hard :

Code: Select all

r3kb1r/4Pp2/pn3P2/1pp3B1/2p5/2N3P1/PP3P1P/3RKB1b w - - bm h4;

### Re: Hard-Talkchess-2019 set

I want to express my appreciation for your enormous efforts on these tricky test sets.

You have an eye for the beautiful.

If people were told the total effort you put into a thing like this, they would think you were joking.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Hi Vincent,

In this position: r1q2rk1/ppp1bp2/6p1/3pNPn1/7p/2PP3P/P6B/1R1Q1RK1 w - - 0 1 (Nr. 177 in the initial list)

I've found out 1.Rb2 are equal to 1.f6

Analysis by Stockfish 250719 64 BMI2:

1. +- (3.64): 1.Rb2 Bf6 2.Rg2 Bxe5 3.Bxe5 f6 4.Qg4 Qd7 5.Bd4 Rae8 6.Qxh4 Qh7 7.Qxh7+ Kxh7 8.h4 Ne6 9.fxe6 Rxe6 10.h5 Rg8 11.Bxf6 gxh5 12.Bd4 Re7 13.Rxg8 Kxg8 14.Rf5 Re2 15.a4 c6 16.Rxh5 b6 17.Rh8+ Kf7 18.Rh7+ Ke8 19.Rxa7 c5 20.Kf1 Rd2 21.Bf6 Rxd3 22.Ke2 Rg3 23.Re7+ Kf8 24.Rd7 Rg4 25.Bd8 Rxa4 26.Bxb6 Re4+ 27.Kd2 c4 28.Bd4 Rh4 29.Rxd5 Ke8 30.Rd6 Rh7 31.Rc6 Kd7 32.Rxc4 Rh2+ 33.Kd3 Rh3+ 34.Ke4 Ke6 35.Rc8

(Depth 52/98, 3 cores @3.7GHz, 8192MB Hash)
Thanks !
One more to take out !
Oops, I forgot to take out this one. I'll do.
This will be Beta3.

I plan to run Stockfish (15 minutes, 6 cores) 3 or 4 times. Most of this is already done.
+ I'll run Houdini 1.5 and Critter 1.6a later.

One more idea is to create studies on Lichess for all the good and the bad test positions.
For what I know, there's no tool to find a position on Lichess, so we have to make link between both here, on the forum.

And I'm adding 6 older positions, sometimes easy and sometimes hard :

Now I remember why this position is not good : Rc8+ is sometime evaluated as 0.00 as some other moves.
I'm removing this one.

Thanks, Dann !
I'm certainly not the only worker who made this wonderful compilation possible.
Numerous computer chess enthusiastic people like you spent time and energy on hundreds of interesting positions, checking and rechecking variations, trying to find the weaknesses of engines, trying to understand why this key move is found and another one is not found and so on ...
I speculate that if we take only the 10 more devoted analyzers here, we spent more than 100 000 of hours*cores to verify fascinating positions like this.
Since I got my 6-cores computer, 5 years ago, I estimate I ran around 50 times, around 200 positions set, around 15 minutes per position on 6 cores, that means 50*200*6*15/60 = 15K hours*cores.
Manual check of variations is also a part of the job, it's difficult to estimate the time spent on this, probably more than 1000 hours.

It's a good opportunity to thanks all the contributors ! Especially : Dann Corbit, 'Paloma', Marek Kwiatkowski, Louis Zulli, Michael Byrne, Jon Dart, Marco Costalba, Marc Moisan, George Tsavdaris, Ferdinand Mosca, Walter Eigenmann, Peter Martan, Joseph Ellis, 'tpoppins', Louis Zulli, 'Werewolf', Kim Burcham, Ed Schröder and all those I forgot who spent time on those analyses.

Vincent, are you sure?
This position seems to be a very good winning one.
Good luck!
Maybe, I can't be friendly, but let me be useful.
