Hi,

in my collection I didn't found any other items with Elo levels that you named before - so this feature is very rare

There are many UCI-engines with that feature that I use sometimes, also in a game against chess computers to align them to an equel level. Some UCI-engines do it well, others in a bad manner (e.g. loosing figures and then play strong to compensate it).

To align chess computers to my level or to known Elo levels (active ot tournament Elo list) I use limiting of of the calculation depth in half moves - that is provided by several chess computers. In principle it should be possible to make a sheet with Elo-ranges and the corresponding depth in half moves that chess computers reach in this Elo range.

Regards
Achim
