Hi everyone,

It's been a while since I released a version of my engine.
I have been working for it for a while but then my latest work has become
a disaster so I decided to start all over again from the last released version.
This is the result of that second effort now. I have tried my best to eliminate all the bugs
I could find by scouring the source code thoroughly. It was only 3500 lines of sparsely commented
C source code. I think this version is 100 or more elo stronger than the previous release but
I am not that sure since I have not tested this a lot.
Feedback would be welcome. Enjoy!!

Edsel.

Hello Edsel

Wow, what have you changed since earlier versions ? I remember playing your earlier version and my program won rather easily, I have tried this new 0.37 version and it is slaughtering me !!

Twisted Logic is currently winning 38-9-12, that is even more conclusive than the score for the new version of Colossus against my program.

I would guess you have improved it by several hundred ELO, I havent tried it but suspect that you might even beat Colossus now

Hi GeoffW,

I just printed out a hard copy of the source code of my program and search for the bugs thoroughly. I have fixed a lot of bugs by that method, in the eval, in the SEE, in the transposition table, and a lot more. I even wondered how my program used to beat other engines before because of the bugs it had. Right now, I want it to support more features, like checks in qsearch, endgame bitbase support, UCI and pondering but I don't have much time. I'm still studying in college and I do have lots of other interests to pursue. Anyways, hope your program would improve too. Try to study source code of strong programs.

Best Regards,
Edsel
