BOOO gets a time win, Chess Assistant 9 time management?

Yesterday, BOOO,, the anonymous player, who has drawn TransWarp before, achieved a win on time. I was using Chess Assistant 9.1, which is known to have time management problems, I normally never use it for onliine play, but for sorting out databases and looking for certain openings and variations. But since my ChessPartner 5.4 was in the shop, so to speak, I had to use Chess Assistant 9. I do NOT know if Chess Assistant 10 & it's upgrade 10.1 have solved this time management problem, but I don't really see anyone using it as a gui to connect their computers to ICC, so I'm guessing they haven't.

Chesspartner 5.4 is very good at managing it's time and usually does well in all time controls if you have it set right. I switched computers from HP to Dell and suddenly, it doesn't recognize 4 cores. I figured out it was a long filename problem and after renaming the long Rybka filename, all was solved and she's riding her old horse Chesspartner again.

But to give BOOO credit, after analyzing the position where it lost on time, the position was drawn. Rybka showed a +1.00, but as the analysis got deeper, the score got lower, to less that -0.50 (black advantage to computer analysis neophytes.) When white has an advantage, it's always a positive score, such as +0.50 for a guesstimate of a 1/2 pawn advantage. For a strong advantage, it would be like +3.00, or the equivalent of a minor piece, Rybka also takes into consideration the position on the board, so even though it's a K+P vs K endgame, where you would think the most the computer could give as a score is +1.00 (1 pawn) the position is also considered, if it's a winning position for white, it could be +9.00+ or even a Mate in # score, but if black's king can defend to where he can draw the position, the score would be 0.00. Just reverse the scores for black advantages, ie. -0.50, -3.00 and -9.00+ etc. So a quick, but I hope not confusing computer score lesson. A note, some engines tend to give higher scores than Rybka in some positions, especially older crafty engines. It's just a manner of how the programmer set up his/her value system for material and position...too complicated for me to make an engine, that's for sure.

Also, again GM Mamedyarov played some games this morning, not as many as the two previous days, but at least TransWarp is climbing back up towards it's 3940 high...but a ways to go at 3910.
