This is how the communication when the engine boots can look like:

GUI     engine

// tell the engine to switch to UCI mode
uci

// engine identify  
      id name Shredder

Notes for Call (2/5/14)

• Boomerange detection progress: how good is that bishop move?
• => get "free" material on first move which leads to catastrophe later
• => 180: Alekhine-Levenfish (ideal)
• => maybe Rasmusson-Niemi
• => 184: Lasker-Ragozin
• => 176: Nielsen-Amateur (black's POV)
• => 174: Richter-Amateur @ 3-pli
• => important to search odd plies

## Detecting Boomerang combinations

* For each Maurice boomerang example:
* Translate board positions into fen
* Tell Stockfish to set the board position (over UCI)
* Request a white move with limits on search depth (parameter)
* Play out move sequences at full search depth
* Track centipawn score (for black move) and loss of material/checkmate
* Automate this.

atduskgreg

* Understand info line (especially what move centipawn (cp) score applies to)
* Get centipawn score for each "bestmove"
* "Graph" centipawn score for best move for white and black for series of moves after bad move
* Suggest values for boomerang outcome "threshold" (to detect a big change, i.e. loss of queen, checkmate, etc) "losing the exchange"
* Do this for more of Maurice-suggested games
