4 draws eh? Pradu must have improved his engine is a lot.

It's interesting that the same opening (SOC 3209, KID 3. Nc3) came up twice in four games as Symbolic's ICC book is rather wide with just over five million positions.

Symbolic was running on a fast processor (2.66 GHz Xeon), but with relatively small transposition tables. The box has only 1 GB RAM and I use it to do other things while it's playing chess. So, Symbolic limits its memory footprint to avoid disabling paging. I hope to upgrade to 5 GB RAM soon and this restriction will disappear.

Symbolic on FICS is also memory limited as its box has only 512 MB RAM with 64 MB reserved for vampire video. I hope to get this box bumped to 2 GB soon as it will be the online test harness for the cognitive searcher.
