unless there is something wrong in the quiescence search.


Yes, there was an error that cause this wrong move. That error has
been removed. Analysis with Easy Level gives clear analysis.

I liked the way crafty shows its evaluation in tabular form. Now play
with Easy vs 7th depth. I think now it will be able to give good
challenge since that error has been removed.

After the game do show me the evaluation by Crafty So that I may find
which move is wrong.

Then let me know time taken by Crafty for playing 7 depth. GetClub
Takes 1 second to compute till 7 depth.

I played a match using only one core and no thinking on opponents
time, with the search depth set to 7. GetClub was running on a
different machine, which is about as fast as a single core on the
machine crafty was running on.

OK. So no risk of interaction then.

Below is an extract from craftys log file, which shows (second column)
that the thinking time is between 0.01 and 0.17 seconds. The third
column shows craftys evaluation of the position, where + is good for
white and - is good for black.

GetClub played ok until move 13. I don't see why it would play Rf3
unless there is something wrong in the quiescence search.

7- 0.08 -1.00 11. ... Re8 12. Kh1 Kb8 13. f5 Bh5

Interesting here that Crafty at this limited ply search hasn't seen that
there are consequences to Re8 and thinks it is ahead.

7- 0.07 -0.23 12. ... c6 13. Nxd7 Nxd7 14. f5 d4

It has seen the most obvious continuation line for white now and adjusts
its evaluation accordingly. But Getclub didn't even with an extra ply.

7- 0.05 -2.46 13. ... Bh5 14. Bf5 Kc7 15. Nxd7 Bxf3

Can't argue with that it is the natural perfect move here and Getclub
has set up the R & Q ready to be skewered. It should never do this
unless the alternative to losing the exchange is a forced mate or losing
even more material!

After 11. ... Re8 Getclub is marginally ahead but doesn't know it.

12. Ne5 c6
13. Rf3 Bh5

And here Rf3 is absolutely tragic. It is about the 30th best move and
there are about 10 reasonable moves that would keep white in the game
(and another 10 that are not really losing by very much).

But setting up a RQ skewer for immediate use by black takes the biscuit.
We need to understand why the program though this was a good idea!

Qf3 would be playable since she can defend herself along the diagonal.
Qe2 or Rf2 or Kh1 would be OK too if the K check paranoia is high.

It overlooked its own combination here that I think should have been
within its search horizon so I am mystified why it did not play at least
something that wasn't immediately losing. My best guess is some
misguided King safety term that is terrified of Q checks (hence the
spite checks).

Or it could be a quiescence problem at precisely 6 ply in white might
believe it was a Q down if the recapture 16. Bxg4 was not considered.

The winning line for white runs something like
13. Nxd7 Nxd7 (exploiting the pin on the K)
14. f5! Qg5+
15. Qg4 Qxg4+
16. Bxg4 Nf6
17. fxg6+ Nxg4
18. gxf7

And white has a pawn on the 7th rank with a R behind it.

Here is a complex Game by Beginner. It game away pawns for no
reasions. But on analysis on Computer I found they were correct moves
and It lost two pawns in just 15 moves. The Computer Analysis said
those were correct move, But still I feel those are wrong move.

8. Bc4-b3{10} c6-c5{12} This Move by Vlack gives away a pawn for no
reasion. But I saw for other moves too the score was -1. So whether
you sacrifice pawn or not the score is -1. Why?

10. Ke1-d1{6} Nf6-e4{6} Here again It lost a pawn. Can find whats
wrong with this move that it again loose a pawn.

I suspect your program overvalues the QxQ KxQ and loss of castling
rights. The king isn't so vulnerable once the queens are off.

10. Ke1-d1{6} Nf6-e4{6} Here again It lost a pawn. Can find whats
wrong with this move that it again loose a pawn.

Ne4 is a terrible move. It sets up a bishop diagonal fork the opponent.

(Jester) -- (beginner)

8. Bc4-b3{10} c6-c5{12} {Wrong Move by Black}
9. d4-c5{20} Qd8-d1{6}

Yum! A pawn for gratis and it poses no real problems for white.
Something along natural development lines would be OK for black
eg Bf5, g6, e6, b5

10. Ke1-d1{6} Nf6-e4{6} {Is it a wrong Move?}

Decidedly a wrong move - puts the knight in harms way.
Correct was something like 10. ... Bg4

11. Bc1-e3{12} e7-e6{6}

But white misses the plot here. There is a fork with a check but the
knight doesn't get to ride home whereas the bishop lives to fight
another day.
11. Bd5 Nxf2+
12. Ke2 Nxh1
13. Bxa8 b4
14. Be3 Ba6+
15. Kd2 g6
16. Rxh1

I was thinking there are two errors. But on analysing on my slow

doubt if anything is wrong with 10.......Nf6-e4{6} and 8. ..... c6-
c5{12}

They are both poor moves. 10. ... Ne4 particularly so.

I suspect c5 signifies you have too high a weighting on king protection.
It isn't worth a pawn sacrifice just to swap queens and stop white
castling.

Back it off a bit until a more natural move is proffered.

Re7

We are agreed up to here.
And I grant you it isn't anything like as winning as I thought it was.

I think the other continuation peters out
19. Ne2 Nh6 20. Bd4 b6 21. c4 dxc4 22. bxc4 Rxf7 23. Rxf7

19. Kg2 Nf6 20. Ne2 Rxf7 21. Bxf6
gxf6 22. Rg1 Bc5

Or for this line since we can't save the f pawn push the e instead.

20. Rae1 Rxf7 21. e4 Re7 22. e5 Nd7 23. d4

Black is decidedly cramped.

There doesn't seem to be any way to defend the f7 pawn.

No, but white has a space advantage out of this. And a passed e pawn.

I played another game between GetClub easy level and crafty limited to
7 ply search depth. GetClub didn't make any big tactical errors
according to crafty, but was slowly led into a losing position,
probably because crafty has a better positional evaluation function.
