I think that progress is still simple and it is possible to improve your program by 50 elo only by changing less than 20 lines in the code(the problem is only to think about the right ideas). > i will have to take a good look at my evaluation for instance, Yes I believe that it is possible to improve the program significantly by improving the evaluation. and at >the various extensions, and do a lot of testing. i don't believe there is any >magic bullet that will do the trick. I believe that there are a lot of magic tricks and the problem is to find them. I hope that after almost 3 months with no significant improvement I found today one magic trick in the evaluation to get a significant improvement by adding only few lines of code(no promise). First tests are promising but of course even if there is improvement of 50 elo then testing of more than few hours is still needed to verify it. I look for ideas that will improve my program significantly without a lot of changes in the code and I believe that there are a lot of ideas to do it that I still did not find. Uri
