Hi, Ferdinand,
50 cp very high for a draw, if Houdini or SF eval to 0.50 it's already a nice advantage.
I'd call drawish a score below 10cp-20cp, let's take the average 15cp.
For a win, I'd say, for a top engine, +200 to +300 is winning, let's take the average +250.

My best,
Vincent

I make this as an option now.

Code: Select all

--draw 15 --win 250

I will make some minor changes in engine log and perhaps in the output, also include the hmvc value if there is, the released version just use zero when fen is sent to engine. Fortunately your epd has value zero in hmvc. The fmvn is ignored and will just use 1.

I may add, this tool is not capable of determining correctness of bm or other conditions when epd has am and bm at the same time.
At present bestmove of engine is compared at c9 "moves". Now if there is am and bm, I am thinking of placing the am moves in c8 "moves"; and bm will be in c9 "moves";. But this is not a priority.

Revised the output, also now will consider hmvc value in epd. Improve engine log on avoid move. Added draw and win threshold options.

Thanks for your nice app and for the improvements of the epd file.
The next position is a distance to mate too, I'll reanalyze this evening.
I'll change the set too, because there are really good positions in the "Die Tactical Suite" I posted yesterday.

There is likely some crossover with problems from your list. These problems are very hard to solve. Some of them are clearly alternate solutions (e.g. score of +1403 for one of them). You might like to include one or two in your list, if they are not already in there.

The next position is a distance to mate too, I'll reanalyze this evening.
I'll change the set too, because there are really good positions in the "Die Tactical Suite" I posted yesterday.

I don't like many of these "alternate solutions".
1) Long zugzwang, I won't add it.
2) Qxf6 is way stronger than Qd4.
3) e6 is around +1.40 and Bf5 is around +0.75
4) I already commented there are 3 solutions for this position. I will take it out.
5) Rg5 is way stronger than Rh3.
6) I don't understand why Qa3 would be good here ...
7) Rxe6 and Bxe6+ are both around +4.00 after 10 moves. Not a good test position.
8) Bxc5 is mate in 22, see here : https://glareanverlag.wordpress.com/201 ... more-12695
9) Rxf5 is way stronger than Rd2.
10) Rd8 is winning yes. Ng5 is interesting too ...
11) Nxf6 and Rh3 seems winning both. Not a so hard position.
12) Neg5 seems stronger than Kb1 but I'm not sure about the endgame Q vs RR.
13) gxh5 is close to Nf5. Both are easy to find, not very interesting.
14) Nd2 and Ng5 seems close, not very interesting.
15) Yes, Rxh2+ is very strong. 1. ... Rxh2+ 2. Bxh2 Qh4 3. Qg1 Rf8 0-1
16) Nd6 seems stronger than Nxb6 -> 1. Nd6+ Bxd6 2. Bxf7+ Kxf7 3. Bxf4 Bxf4 4. Nxf4 Qh4 5. g3 Qf6 6. Nh5 -> eval +4.30 !

For each of those positions, the proposed solution is found in field c3.
You will see that a very long search failed to find it.
That is why I posted them.
The bm field is automatically filled out by a stored procedure that I use.
I use c3 for the "original" bm.

I understood, that's why I commented with the 2 moves.
But 2 times (#10 and #15) you give the 2 same moves, one with "+" and one without.
