Happy New Year!

You can download the latest Hannibal version here:

http://sites.google.com/site/edapostol/hannibal

Changes are SMP and search improvements. It should be around 35 elo better than the previous version. Not much but we only have spent around one month working on it.

I hope the best for Hannibal in the coming year. But no matter how strong it gets, I will always miss "Twisted Logic."



Best,

george

But TwistedLogic is there also to play with it....

It didn't die or something

Thanks!

Here's a game from last year [from one of Graham's CCRL tournaments] that shows Hannibal's potential (Critter's bishops were both reduced to being mere pawns):

Very nice game Carl! There are some occasional motivational challenges that accompany developing an original engine that is weaker than the top open source ones (which means having to watch new authors regularly publishing engines stronger than yours). It is very rewarding, however, when people express appreciation for those aspects of your engine which set it apart from others (and restricting opponent piece coordination is definitely something we do differently than others). Thanks for the kind words, and we will see if we can bring you some more improvements in 2013.

Keep up the good work, Sam, I'm rooting for you guys. I have imagined how frustrating it must be for developers to work for so long at creating an original product. One shouldn't worry about what others are doing, in my opinion. If the product is unique and effective, it will have value that can't be measured in rating points alone. I like using Hannibal in analysis, even though it's not the strongest engine. Why do I do it? Because it suggests moves few other engines would consider, yet are challenging and hard to meet by any opponent. This is the kind of ideas that I find particularly useful when preparing for real life over-the-board chess encounters.
