Fritz would also have preferred Rh8 instead of b6 (I let it ponder for
15 minutes on the 233MMX), the line Fritz gives after 36...b6 is 37.Rxc4
dxc4 38.Nh4 Kg8 39.Qxh6 Re7 40.Qxf6 gxh4 41.gxh4+ Rg7 with advantage for
black.
Here is Shredder's logfile from the actual game

On my P233MMX with 98304 KB hash tables, Fritz only discards 34.Rc5
after 47 minutes (eval about -0.56, 14ply depth) and prefers 34.a5
instead (fail high and confirmed as better but no PV and accurate eval).
