I have analyzed the end position of the second game of the rematch between Kasparov and Deep Blue with Rebel9 and had some strange results. When i use power analyze on Qb6xc6 and Qb6-e3 separately it gives the following score on the PV: PLY Qb6xc6 Qb6-e3 10 -0.82 -2.34 11 -1.00 -1.76 12 -1.23 -1.52 13 -1.37 -1.41 14 -1.38 -1.18 15 -1.56 -1.76 When i use power analyze on Qb6xc6 and Qb6-e3 together it gives the following score on the PV: PLY move 10 Qb6xc6 -0.81 11 Qb6xc6 -1.00 12 Qb6xc6 -1.23 13 Qb6xc6 -1.37 14 Qb6xc6 -1.43 15 Didn't wait because i expected it to switch PV on ply 14 With normal analyze it swiches from Qb6xc6, score -1.56 to Qb6-e3,score -1.53 on the 15th ply. Why not the same score and ply depth switching between these two moves? has it to do with hash-tables? beste regards, Ernst.
