Hello, I have been carrying out some testing between shredder 8 and king 3.33 (Schumacher) in fritz gui and noticed that king is so far drawing shredder in 5 min games, using 5 moves.ctg and 4 and 5 tablebases. Firstly is it best to click the box play in open positions in shredder 8s engine parametres or leave un ticked, what is strongest? So far King is winning 27 to 23 which somewhat doesnt surprise me. I know that over 50 games this doesnt give me the consistency to prove that king 3.33 is stronger than shredder 8 as more games are needed. Im going to keep working on king settings and try to play more games and analyse games myself and compare with current king parameters to try tune better. If i tested king with shredder over say 10 min,15,20,30 and eventually tournaments style controls wud shredder prove stronger as i hav heard previously on here it gets stronger at longer times. I am not certain but watching some of the game today there were times when i though the kings endgame teachnique seemed suspect or this could be shredder playing perfectly, do both engines hav equal access to my tablebases as i set them both for access but just think shredder is utilizing them better, why is this. Furthermore, king 3.33 seeme stronger than shredder in some positions as i have also noticed that once shredder is playing white or EITHER black and ahead in material by say only a pawn, its evaluation shoots up to + 1.79 or adding extra values whihc i cannot see its ahead in. Obviously these extra values might be pawn structure, positional advantages,king safety,ect.Yet, still in the same position when king is down its evaluation remains realistic at -0.80 as opposed to an optimistic +1.79. The different evaluation fucntions both engines incorporate tell different stories as there playing styles are different. Persoanlly, since watching king 3.33 destroy fritz 8, i have taken a likening to kings very solid approach as a realistic chess engine and its positional play is very good. Then again shredder can get in to exceptionally good positions and its endgame play can be perfect. The fact that shredder is a rather optimistic chess engine might be a bad or good thing as it can over exaggerate as its evaluation function seems arrogant. Both engines have their ups and downs. Finally, since shredder 9 is now coming out on 10 th feb, i have a positive feeling that its evaluation function mit be tweeked or tuned down a little and its plays will be stronger than shredder 8s. Im certain it will be stronger than king 3.33 schumacher setting, therefore it will be king of the castle.Im going to try testing king 3.33 with shredder 9 to see how strong shredder 9 is. Does anyone know if there will ever be a king 3.33 for multi processor computers -deep king 3.33? as shredder has now done this it would be fascinating to see king in a deep version as well.
