It is useful to know that. black may or may not have compensation, but if you do not try you will not know. >Who knows, perhaps white has a passer on >the 7th row already promoting in 1 step. yes a 60 ply material search will not reveal a material gain on 61 ply. and similarly a 34 ply material search will not reveal a material gain on 35 ply. the solution is NOT to not bother trying to go for a 34 ply search, but to first try to get to the 34 ply search and then later as resources allow to get to the 35 ply search.
