I can almost guarantee they will reveal that your program: (1) doesn't extend enough on checks OR doesn't score king safety highly enough. (2) doesn't score passed pawns highly enough.

(5) has multitudes of positional problems you never even dreamt of. The servers did all this for me and more. :) James >A few weeks ago there were some posts about an ICC Winter tournament with >tentative dates in late Jan and early Feb at 75 10, as I recall. > >What is the status of this event? > >Also, I am hoping to get some suggestions on the "most important" next features >to add to my program, either in general, or to prepare for this tournament. > >My (as yet unnamed--I know boring--I can really relate to Insomniac), program >has the following features: basic TSCP-type search (iterative deepening and >history with full quiesce) with usable subset of Winboard support, non-rotated >bitmaps, simple hashing (only one table, simple draft replacement), null moves, >killers, internal iterative deepening, and some (hopefully significant) eval >changes.

Do others with more experience still run into these situations ?
