hard position

Post by jdart » Fri Apr 20, 2007 7:12 pm

From Ivanchuk-Dreev, Leningrad 1985:

[D] r1b5/ppq1kppQ/n1prp3/8/2P5/8/PP2BPPP/3R1RK1 w - -

bm is Qxg7. Arasan gets this, but it takes 10 minutes (on a relatively slow machine), and 17 ply.

Full game follows:

[Result "1-0"]
[White "Ivanchuk Vassily (UKR)"]

I do not understand why do you think that this move is hard.

Here is movei on a slow machine

It likes Qxg7 very fast in less than a second at depth 8.

I think that the position is not hard and the question if to play Qxg7 is mainly a positional question.

The main problem is that some programs do not have evaluation that tells them that white is better and for some reason they are happy with a draw score but even in case of toga1.2.1a that is not very good in test positions it can see Qxg7 in less than a minute on a slow machine.

edit:after some analysis it is clear to me that Qxg7 is equivalent to Qh4+ Ke8 Qh8+ Ke7 Qxg7 so the position is a bad test position.

Well, with any test you can select the right move for the wrong reason.

White should avoid the draw, so maybe a better test is on move 19, where your pv (and the one I got) has Rxd6. Ivanchuk played Qxe5+ - maybe this is even better, I have not analyzed it.

I don't think Qxg7 is the best move.
Or, at best, it is somewhat doubtful.

Dann, you are confounding my poor brain. :D
You and Robert Yatt said that the best move is anyone that
wins the game, and Qxg7 wins.

Qxg7 wins but Qh4+ also wins so it is a bad test position.

If 2 moves win then the move that force mate faster can be considered as the best move and it is not clear that Qxg7 mates faster than Qh4.

Uri, the concept of best move, according Dann Corbit and Robert Yatt, does not take account the fast mate.
I think it´s rigth, because it´s dificult to know what move it´s the best in the case of fast mate.
This position is an example, I agree with you.
I don´t agree with your concept, a position can be a good test with one or
more best moves.

Two different issues. For any given position, I believe that any move that wins the game is a "best move". But for a test position, it is far better if it has exactly one "best move". One move that forces mate, or one move that wins material, etc. Positions with multiple winning moves are not good test positions since it is harder to say "right or wrong" for any one move choice.

Hi Jon

up to 47 minutes CMX(SS16PP200) likes Qxg7 then switches to Qh4+ after 1 hour with a score of +2.83...

Robert, look for the position above, test number 5 from Eigenmann_Endspiel_Test.
I like this position, because I have the curiosity about what move will
the engine play. Some engines plays Kb3, and others , f5.
