How to list all the expected moves (PV)?

[mike_bike_kite]

the program has calculated what it thinks is the best move but now I'd like to show the expected line of play from the current position. It would be helpful for debugging as well as showing the user what is likely to happen. Only problem is I can't work out how to do it! I've tried a few approaches but all give nonsensical results.

I recommend the first approach from the first link... it's easy to implement, doesn't have a measurable impact on performance, and on modern machines the memory it consumes is hardly significant.

Thanks Ricardo - I'll try and digest that.
