// Made this Debug V3 script into official script due to it is working correctly
// Working Stockfish V16+ using their API
// Debugging V2 script Found out engine is not responding due to not finding a legal move
// Debugging V1 script engine responded but did not move
// Using stockfish V10.0.2 as it is working
// Removed CDN stockfish V16 engines and engine fallbacks because it doesn't work
// Added engine fallbacks if an engine fails
// added error handling and alerts
// Upgraded from Stockfish V9 to Stockfish V10.0.2
// Using Stockfish 9 currently
