below is a response that was made to one of my posts. this was a mate in 11 that i got with the same program. i was unsure about the results because none of my other programs could find this mate in 11. now rex also has found this mate in 11. so i assume this is a true mate in 11. now the original question that i had. i also got this same eval, tiger shows a mate in 11, but could not see the mate until depth 16, and this was about an hour after depth 11, on a 1500 mhz. could you explain how the search works to get these results. in other words after a program advances its search to say a depth 12 , is it also still searching each ply below this even though it may have posted a depth 12 result. so in this case when tiger posted the depth 15 level results, at that time was tiger also expanding the depth 11 search beyond its original post at depth 11. also can we say that no matter what depth has been posted, a program can anounce a mate in ? (any lower level of its search) at any time. kburcham Here are the results running GT2 on a T-Bird 1.533Ghz.
