I played a game just now, (Hard), a Sicilian with White and it was badly mauled by me. It tries to exchange when down in material and is also prone to going after pawns or picky the daisies with its Q at the expense of its K safety.


Estimated rating less than a 1000.

I would like to request a "take back" button, please! :oops:
I'm an abuser of the "take back" button that lead me to play without thinking so I prefer not to add it for now :roll:

I tried a few more times to reproduce the mysterious rook but it is not happening again. What would be nice is maybe a small sound when it plays a move. Also a replay button to play through the game again. Level seems around 1600 to 1700 against humans which for an engine is probably around 2000 tactically and 1200 positionally. The "hard" setting is actually probably weaker against humans since it plays very slowly allowing the human to avoid tactical mistakes.

The sound when the applet moves is a good idea I put it in the to do list with an easy way to copy and paste the moves of the game in PGN format with in the header: date, site, level, ecc...
Anyway you can already copy and paste the moves of the game for example in Arena GUI and then review the game and save it in PGN format.
The engine is slow because of the array board coding that in Java has an overhead caused by the run time bound check. When I will have time I can add transposition tables, null moves, pawn hash tables, etc to speed it up.

I've just now uploaded on the site http://bremboce.cisana.com a new version of the applet that plays a sound after each computer move.
Thank you for the idea.

I tried it with sound feature and is much better. Also no more rook adding bugs.
