The discussion about using computers in internet chess we sometimes have had on other chessservers.
The difference is,if you play "livechess" (the same like otb-games) for instance at ICC,USCL or Playchess.com,you play only one game at the same time,mostly fast-3 or 5 minutes- and the using of helps is forbidden.The servers can sometimes control it.At playchess.com (Fritzserver) they have a running software,which disqualifies cheaters automatically and every day you can see sometimes such a message in the display : "disqualified because of using chess software".In addition there is a "machine room",in where you can play as "centaur" (=human-machine).

An other fact is at turn based servers.Here we play like correspondence chess,many games simultaneously with long times and both players must not be online at the same time! And in correspondence chess, there are no prohibitions to use helps, advices,computers,books or other things.Neither the "International Correspondence Chess Federation" (ICCF) prohibits something nor the special Brainking rules.And also this wouldn`t make sense,if you cannot control it really.And that`s why all the worlds topplayers in correspondence chess are playing with all helps they can have.:
In the past only with books and common analyzing in the chessclubs,today additionally with computers and big databases.
It is perhaps not a very good evolution for the correspondence chess.It is now "centaur chess", but it is not cheating!
In "Gothic chess" I see there no problems, because the programs are much weaker at the moment as the strong chess programs (like Fritz,Chessmaster,Shredder).The best is if you analyze mainly for yourself.(excuse my bad English)
