Conclusive Report
(but without any evidence)
I began this round of playtesting using SMIRF MS-174b-O which contained
a bad checkmate bug. Since I regard it as inconsistent to me to:
1. present saved games unaltered whenever the checkmate bug did not
present itself.
YET
2. present saved games altered whenever the checkmate bug did present
itself.
... I chose to present no saved games at all for the sake of consistency.
In fact, I did not save any games at all generated via SMIRF playtests.
This puts me in the strange position of playtesting mainly for my own
interest since I do not have the right to demand that anyone else take my
word for the playtesting results I am reporting.
[The latest version of SMIRF recently given to me by Reinhard Scharnagl,
MS-174c-O, has never shown me a checkmate bug. Hopefully, it never
will.]

Since I have been convinced thru playtesting recommended by Muller that
the archbishop has a material value nearly as great as the chancellor in
CRC, the desirability of confirming the order of material values for the
'supreme pieces' (i.e., queen, chancellor, archbishop) used in all
reputable CRC models occurred to me. Accordingly, 3 asymmetrical
playtests were devised. These are 1:1 exchanges involving a player
missing 1 given supreme piece versus a player missing 1 different supreme
piece. Generally, the results were normal as expected.
Embassy Chess
(player without 1 archbishop) vs. (player without 1 chancellor)
10 minutes per move
(player without 1 archbishop) wins 2 games (playing white & black)
75% (3/4) probability of correctness
(player without 1 chancellor) vs. (player without 1 queen)
10 minutes per move
(player without 1 chancellor) wins 2 games (playing white & black)
75% (3/4) probability of correctness
(player without 1 archbishop) vs. (player without 1 queen)
10 minutes per move
(player without 1 archbishop) wins 2 games (playing white & black)
75% (3/4) probability of correctness
order of material values of CRC pieces
(from highest to lowest)
1. queen
2. chancellor
3. archbishop
By transitive logic, the third playtest could have been considered
totally unnecessary. Nonetheless, I conducted it as a double-check to the
consistency of the results from the first and second playtests.
Although a 75% (3/4) probability per test could be improved upon greatly
with a couple-few more games, I am already satisfied that the results are
correct and that something unexpected is not the reality. So, I will not
be playtesting this issue further. There are more interesting and
pressing mysteries to me awaiting tests.
