 # ChuckooChess 1.12

 ## About the program
 
-Most of the ideas in the program are from the Chess Programming Wiki or from the TalkChess.com forum.
+Most of the ideas in the program are from the [Chess Programming Wiki](http://chessprogramming.wikispaces.com/) or from the [TalkChess.com](http://talkchess.com/forum/) forum.
 
 The program implements many of the standard methods for computer chess programs, such as iterative deepening, negascout, aspiration windows, quiescence search with SEE pruning and MVV/LVA move ordering, hash table, history heuristic, recursive null moves, futility pruning, late move reductions, opening book and magic bitboards.
 
-The program is rather slow compared to state of the art chess programs. However, it is still quite good at tactics and scores 299 of 300 on the win at chess tactical test suite, at 10 seconds thinking time per position, using an Intel Core i7 870 CPU. The only position not solved is the extremely complicated position 230, which according to current analysis, seems like a draw and therefore an invalid test position.

 ## UCI mode
 
-It is also possible to use the program as a UCI engine, which means that you can use it with many graphical chess programs. For example, to use it with XBoard/WinBoard + polyglot, set EngineCommand like this in the polyglot ini file:

+To use the program with the [Arena](http://www.playwitharena.com/) GUI, create a one-line bat-file containing:

+    javaw -Xmx256m -jar cuckoo-app-1.12-jar-with-dependencies.jar uci
 
-To use the program with the Arena GUI, create a one-line bat-file containing:
+Note that you must set the maximum heap size using `-Xmx` to a value larger than the hash size you set in the Arena program. (I don't know exactly how much larger.)
 
-javaw -Xmx256m -jar cuckoo-app-1.12-jar-with-dependencies.jar uci
