Re: OTB human test positions
All the positions are in FEN, so converting them to EPD is a snap. But copying and pasting them into a single file test suite will take a lot of labor. I'll consider it.David Dahlem wrote:WOW!! Did i hear you say you were converting them to epd test suites?

Btw, MateInX puzzles have been included in "R-Mates" epd databases.

Re: OTB human test positions
Hi everybody:
The position is taken of Shirov - Carlsen of today, but instead of playing 44.- Qd5, I played 'my line', just for curiosity: 44.- Qxc3, Qxd7; 45.- Qxc4, Rc8 (I wanted to trade queens); 46.- Qd3, Qxd3; 47.- Bxd3, ... and here is the position.

I want to ask if there is any kind of fortress for white. I see high evals of all engines, but playing forward with Houdini, the highlights were (not in chronological order):
- h2 pawn goes to h4 and this pawn will trade with the one on g6 to g5 (hxg5).
- Black king goes to e5 blockading e3 and e4 pawns.
- White king is on f2 and f3.
- White bishop is on d3 and f1.
- f7 pawn goes to f6, g3 pawn goes to g4.
- Black rook gives tons of checks in h2, h3... (seems no progress for me). This is why I ask if a fortess exists in this position.
Intel Pentium D930 (Dual Core, 3 GHz, 2 GB of RAM). I have all 3, 4 and 5-man TB of both Gaviota and Nalimov formats. All engines uses two cores, except Komodo. I cleared hash between analysis and analysis.

Any answers will be appreciated. I have not got fast hardware and my chess knowledge is limited, but I think this invented position is interesting and deserves a try.

The position is taken of Shirov - Carlsen of today, but instead of playing 44.- Qd5, I played 'my line', just for curiosity: 44.- Qxc3, Qxd7; 45.- Qxc4, Rc8 (I wanted to trade queens); 46.- Qd3, Qxd3; 47.- Bxd3, ... and here is the position.

I want to ask if there is any kind of fortress for white. I see high evals of all engines, but playing forward with Houdini, the highlights were (not in chronological order):
- h2 pawn goes to h4 and this pawn will trade with the one on g6 to g5 (hxg5).
- Black king goes to e5 blockading e3 and e4 pawns.
- White king is on f2 and f3.
- White bishop is on d3 and f1.
- f7 pawn goes to f6, g3 pawn goes to g4.
- Black rook gives tons of checks in h2, h3... (seems no progress for me). This is why I ask if a fortess exists in this position.

Any answers will be appreciated. I have not got fast hardware and my chess knowledge is limited, but I think this invented position is interesting and deserves a try.

I should have said OTB human test positions that challenge todays programs on modern hardware. I think I said this in the post not sure.Norm Pollock wrote:True, but the thread is supposedly about human test positions.jdart wrote:Most of these seem to be pretty easy for modern engines.

Re: OTB human test positions
Here are 12 positions from human games, taken from the brain twisters collection by Anton Stadlhofer. These are the moves marked with '!!'. If these moves are really best, they might challenge todays programs. My machine is too slow to confirm whether the moves are best or not.kgburcham wrote:Does anyone have a collection of OTB human test positions that will challenge todays programs?
I wonder how many positions that have been played by humans that challenge todays programs?
I would think there are not very many of these.
Of course it does not mean they have to be winning moves, just that they challenge todays programs and cause the score to raise once the move is found. (I am not satisfied with this definition)
I am not talking about Dans unsolved test positions, or some of McMads pattern puzzles.
You can download the entire brain twisters database here.
