Which area of the board is most important?

Since I'm not very good at keeping secrets, here's some information I collected for my bot.  This table shows the number of times this square was moved from during all the games between 1700+ rated players.
 

   748   984  1148  1217  1316  1266   965   631
  1655  2879  2953  3735  4040  3275  3025  1582
  2054  4228  3008  5743  6059  3134  4373  2065
  2180  4750  5111  6382  6612  5245  4869  2139
  2164  4709  4980  6249  6224  4932  4726  2084
  1990  4156  2995  5634  5615  2884  4210  1912
  1540  2757  2961  3729  3793  3036  2957  1571
   672   895  1130  1164  1184  1182   949   655

 
Notice that the centre of the board is the most active, and the traps are not very popular Smiley.
 
OK, OK, I know it's obvious, but I needed these numbers for my bot anyway, and I thought you'd all like to see them.

And here's where the gold rabbits move from:

     1     1     1     1     1     1     2     1
    63    67    54    32    60    59    80    84
   116    74   131    78    89   118    92   180
   202   152   134   209   206   108   180   240
   258   187   185   237   230   191   233   321
   339   149   282   242   218   288   204   364
   433   356   250   470   445   258   412   466
   597   682   799   832   832   790   705   577

 
Did you know they prefer to win on the right hand side of the board?? Smiley
 
Now the silver rabbits:

   648   732   787   844   883   818   684   559
   482   416   238   435   464   291   409   402
   319   192   291   212   206   281   188   324
   268   220   192   241   213   191   184   270
   205   159   110   207   198   130   170   204
   147    80   145    81    79   114    95   147
    63    69    49    58    56    71    86    81
     0     0     0     0     0     0     1     0

Who seem to prefer winning on the same side of the board (their left, the gold players' right).

Here's where the silver rabbits get pushed or pulled around by gold:

    28    73   152   137   161   177   111    31
   103   147   302   177   213   342   161    85
   117   203    15   233   262    20   199    75
   114    76   113   104   112   109    73    85
   147   112   177   116   123   174    96   133
   100   160    13   134   128     7   131    75
    37    31    53    35    30    36    38    30
     0     0     0     0     0     0     0     0

 
For some reason gold hardly ever pushes/pulls rabbits OFF a trap Smiley.

How about when the pieces move (from) of their own accord?

I wonder, if you segregated this data into winners and losers, would you see interesting patterns.  One would be that winners move rabbits from the 7th rank and losers don't.  I keep telling Harry that.  But there may be other patterns indicating pins and framing.  There's a lot of data mining that can be done.  Segregating by move numbers and piece count could also be infomative.
 
Here's an anti-conclusion.  Since good players move elephants from the center squares, avoid them in the first place!  Tongue

[EDIT: I don't disagree... the forum has somehow screwed up.  That was the first line of another post I wrote, not this one!]
 
 
I disagree
umption on the winners vs losers thing is this:
Since both players are rated over 1700, I presume they both make "pretty good" moves [except for maybe one or two moves in the whole game].  Therefore even the losers moves are useful indicators of what is good (at least for my bot who doesn't know any better!).
 
You're right, if there are any statistically significant differences between what winners do and what losers do, then those differences are probably CRUCIAL (masterstrokes or blunders).
 
In fact, the more I think about it, the more curious I am.  Here's the rabbit details:
 
Gold rabbit moves when silver eventually won.

     0     0     0     0     0     0     0     0
     3     4     2     4     5     4     8     9
    27    13    29    23    19    33    15    57
    75    59    45    91    77    30    60    94
   119    93    79   122   110    75   102   138
   167    76   137   126   116   125    89   170
   231   198   153   284   273   156   235   236
   312   386   468   508   502   452   393   287

 
Gold rabbit moves when gold eventually won.

     1     1     1     1     1     1     2     1
    60    63    52    28    55    55    72    75
    89    61   102    55    70    85    77   123
   127    93    89   118   129    78   120   146
   139    94   106   115   120   116   131   183
   172    73   145   116   102   163   115   194
   202   158    97   186   172   102   177   230
   285   296   331   324   330   338   312   290

 
Therefore it is crucial to do a victory dance on the goal row? Tongue

Yes, I am definitely considering taking that kind of information into account.  Also segregating by which way the pieces are pulled etc.  But since there are so many possibilities I don't want to post them all here.

Suggestion about why we(well, not me, hehe) seem to win on the right hand side of the board.  Gold's elephant is initially placed there.  Also, when gold's elephant is initially placed on the right, doesn't silver's elephant usually place on the left(ie silver's right?)  
 
   What would be really interesting, to see how much positioning of the elephant has to do with wins, is if you did an analysis on where a player won compared to where their elephant started the game.  Just a thought.
