Release Notes 1.88
The chess engine has gained a little in strength but that's not the goal of this release.
Version 1.88 is about a new feature, basically Fritz's let's check but faster, more options, more volume, more reliable analysis. More reliable because the database is made of the (annotated) games from the 2 main computer elo rating websites, CCRL and CEGT. An extra second database is provided from the games played in the ChessBase Playchess engine room during the 2009-2013 period.
Example, running ProDeo 1.88 in Arena or Fritz the engine will recognize positions and will communicate the output to Notepad. A typical screenshot.

The list is sorted on depth which (more or less) guarantees the strongest engines are on top. But with a simple parameter we can change the sorting mechanism to sort on score | time and alphabet. And last but not least you can choose your own favorite engine to top the list when positions are found. When we select Pro Deo as our favorite engine and we get this list.
Which such powerful info you must be able to beat a 3000+ elo engine once a month

When set to on book moves are
During the early moves of a game there are thousands and thousands of available moves which is no wonder since the database is filled with 2784 different engines. Therefore the output is limited to maximal 100 engines. However there is little valuable information loss since the database is designed to push the nowadays strongest engines to the top.
Often it happens an engine has multiple same moves but different depths due to the different time controls. In such cases only the entry with the highest depth is displayed.
The database doesn't contain analysis after move 30 since it's not very likely a hit would occur and the already big database would double / triple in size, YMMV. It can be further narrowed with the [ECC Depth = ] parameter.

ProDeo 1.88 engine
Is currently not fully optimized due to the new features of the last versions (1.84, 1.85 and 1.88) that steal some processor time. An optimized (and better tested) version (normal size) will be available later. Meanwhile version 1.88 is interesting enough to release.
