Thanks for the game Chris. It is always interesting to see how chess computers play in this sort of position. BD did well considering how early in the game it got its queen trapped.

Paul now we have three estimates of the Elo value of a Queen - yours, Eric Hallsworth - 1000 Elo and Mike Healey - 800 Elo. Resurrection Fruit played Compuchess I without knights, bishops or rooks. Around 2200 Elo difference on Paul's scale.

All the best
Mike

A totally unscientific hypotheses.  ELO difference is 100 times the basic value of the piece.  P=100pts, Kt or B = 300pts, R = 500pts and Q = 900 pt difference.

Hi Mike / All, 

Well it has taken me ages (again apologies!) but I have the result and moves of the first game.

Just to recap as an unscientific test of the value of a Queen the Boris Diplomat (1150 rating) is taking on the Novag Diamond 2 (2130 rating) playing without its queen in a 4 game match.

Time control is 30 seconds per move (this is perhaps a little favourable to the Novag since it is an average response time, but poor old Boris uses exactly 30 seconds irrespective of the position).

Anyway, very interesting, game is below and if doesn't spoil the suspense, I can tell you the game was .......a draw!! - good old Boris.

First thing to do was to stop the Diamond resigning on move 1 (initial eval was -9.53 

I have all the Novag evals manually recorded but it was interesting to find that Novag made little/no headway in reducing the eval until after move 40. For example:

move 5  -10.65
10  -8.73
15  -7.57
20  -8.61
25  -8.69
30  -10.46
35  -9.65
40  -8.03
45  -6.07
50  -5.42
55  -3.03
60  -3.00

In fact the Novag wanted to resign again on move 19 (funny I thought it was designed only to resign once in a game?) - I insisted it play on and expected the Diamond to make hay in the endgame. Indeed it made the expected comeback and I was getting worried for the Boris and in particular at the end that it wouldn't drop its 'a' pawn. The game ended with the repeating of moves which Novag was happy to accept on the basis it was still material behind. Well played Boris! 

Next game will follow shortly.......

Best wishes


Chris
