Hi all: In answer to a post by J. Walker that showed a game where CSTAl is badly defeated, I have received an email where some doubst about the correction of the test are shed, with the following argument I post here without comments: ....V's and times (for a slightly slower computer, P2 200) for move 19. a5 ?? depth secs move eval 2 0 Qxf7 -9.99 2 0 Ng4 +1.12 2 0 a5 +1.41 3 0 a5 -10.38 3 0 Ng4 +1.12 3 0 Nf3 +1.17 4 0 Nf3 +1.15 5 2 Nf3 +1.09 6 9 Nf3 +0.74 7 27 Nf3 +0.64 and sticks with Nf3 from thereon an "examine e-tal 10" on ICC will pull in the game. This also gives time information. At move 19 E-tal had 2:16 (2 minutes 16 secs) on its clock. 2:16 in blitz at this move number translates to a 4 second time allowance for the move. All this is checkable with a release version of CSTal II. Quite apart from the time panic which would be induced by the eval of -10.38, there is no way that the release version would timeout on depth 2, at (less than) zero seconds elapsed time unless the operator was pressing the move-now key. If the program was left to its own devices it would timeout after the depth 5 iteration (2 secs), or during the depth 6 iteration (before 9 secs). end of the quotation. fernando
