Yeah, that's cheating in any chess {match} it's against the rules to use a book or anything to help you !!!!
Any chance of dynamically linking the word cheating whenever it occurs in the forums so that it links to the section of the FAQ dealing with the rules for playing on chess.com i.e. http://support.chess.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=17&nav=0,6 - or would that spoil the fun?
Tablebases are not the same as databases of games. Tablebases are programs that are set up with pre-calculated optimal responses to positions. The most-often talked about tablebases are endgame tablebases. These have progressed to the point where, for example, you can put any five pieces (either color) anywhere on the board and the tablebase already knows the exact result. Nothing more to calculate, it's already done. It's like a computer that has already done all the calculation. You can buy tablebases to add to your computer so that when you reach these endgames--zip! That's why using a tablebase is using a computer. Not allowed here at Chess.com. (Some correspondence-style chess websites have even given up on banning computers, such as ICCF. But here at Chess.com computers and tablebases are still not allowed.)
Databases are just collections of games you can consult. That's why using databases is like using books, magazines, etc. Chess.com's Game Explorer is just a sophisticated way of databasing and indexing games. These are all permissible in correspondence-style chess, including the turn-based games here at Chess.com.
