+# chess_pos_db_gui

+
 GUI created for the project [chess_pos_db](https://github.com/Sopel97/chess_pos_db).
+It requires chess_pos_db.exe to be present in the same directory.
+A chess_pos_db.exe process is spawned by the gui (previously ensuring that it's not already present by killing all of its instances) and a TCP connection in made through which the requests are made.
+
+The gui is in a rough, but usable state. Codebase is at a prototype-like stage. Don't expect clean code.
+
+Currently the biggest issue is no good chess abstraction in C#. Going by Chess DOT Net's limitations is taking a tall on the codebase. It is a priority to either move to a better library or create one.
+
+# Features
+- Input chess board with FEN field and navigable move history
+- Excel-like data display with easy selection and copying through CTRL+C
+- Creation of position databases from a list of PGN files optionally partitioned by game level (human/engine/server).
+- (Automatic) querying of position data from a loaded database
+- Filtering of queried data:
+
+    - game level (human, engine, server)
+    - continuations and/or transpositions
+
+- Evaluation data provided by (https://chessdb.cn/queryc_en/), building up on a massive effort by Bojun Guo (noobpwnftw)
+- A tool for dumping all FENs for all positions with at least a given number of instances into an EPD file.
+
+# Dependencies
+- Chess DOT Net
