In the following famous position, which I am sure many of you are familiar with, Botvinnik - Capablanca, AVRO Holland 1938 1-0...White (Botvinnik) played the extraordinary 30.Ba3!! and went onto win Brilliantly. The remaining moves were:30...Qxa3 31.Nh5+! gxh5 32.Qg5+ Kf8 33.Qxf6+ Kg8 34.e7 Qc1+ 35.Kf2 Qc2+ 36.Kg3 Qd3+ 37.Kh4 Qe4+ 38.Kxh5 Qe2+ 39.Kh4 Qe4+ 40.g4 Qe1+ 41.Kh5 Black Resigns 1-0 [D]8/p3q1kp/1p2Pnp1/3pQ3/2pP4/1nP3N1/1B4PP/6K1 w My question is will running full games with Fritz 7......................... Hash Tables set at 818 MB cause heat problems for an AMD Athlon 2600+ 1 gig of DDR SDRAM. I have beeb experimenting with Fritz 7 Hash Table settings in the infinite analysis mode. Here are some results based on various Hash Table settings. Time to find 30.Ba3 as a winning move not just to see it in the list of alternatives. Also nodes per second. At 818 MB Hash, I hear no extra work on the harddrive, only when first setting the Hash at 818 for a few seconds then no more. The results from 16,32,64,128,256,and 512 MB Hash Tables respectively were all basically the same. At 16MB it took 3 seconds to notice that 30.Ba3...=(-0.16) and Black is better and then it drops to 0.00...Then at 1:33 it jumps to + 0.34 in favor of White. Then at 3 min 15 secs.it jumps to +-(3.97) kN/s at 1116. At 256 MB it took 3 seconds to notice that 30.Ba3...=(-0.16) and Black is better and again drops to =(0.00)...Then at 1:05 it jumps to + 0.34 in favor of White. Then at 2:00 it jumps to +-(3.31) at 1064 kn/s Now at 512 MB everything is basically the same except the value at 1:02 is at +0.50 rather than the + 0.34 as above. Then at 1:57 it goes to +- 3.88 At 768 the only real difference is that the value at the 1:00 minute mark is down at + 0.34 At 818 I get similar results early on then at 1:03 + 0.50 which is higher than the reading at 768 MB setting, and 2:08 the Highest value at this early stage +- (3.97) kN's flucuate in the low 1000's in all of the settings listed except when set at the 16 MB Hash which was in the 1100's. So basically, will the higher value in the same time period such as the + 0.50 as opposed to the + 0.34 make a difference in a game. Will the higher Hash Table 818 MB settin, yielding an evaluation + 3.99 at 2:10 be better than the + 3.88 at 1:58 with the lower Hash Table setting? My main concern is that I do not want to over tax my processor. If anyone has some insight on this It would be greatly appreciated. Thanks Brian Katz
