GENERAL:

shredder classic :  we can change strength(elo) and playing style

shredder classic: very good for move by move analysing, many engines can be used simultaneusly

another good option is fritz as it tries to explain moves as verbal

still looking for... however books study and strategy concept matters a lot in middlegame

ENDGAMES:

chessimo : however selfpractice and studying endgames studies matters a lot

 chessimo: due to very clear concept as comment provided. However studying masters game is recommended

DATABASE:

I dont know why to use it. I have use this tools rarely just to find out some patterns or position from mastersgames collection

 ENGINES:

spike: very fast and with contempt 200 can go for very high tactical game

togga: stable game

thinker: always ready to sacrifice for initiative

shredder kamikaze: sacrifice material first to gain it later giving game a beautyfull look

TELL ABOUT THE SOFTWARES THAT YOU USE AND WHY YOU PREFER THAT.

Thanks

shredder classic, this engine is good to test strength? better then Fritz 12 that when we play handicap game with the engine programed to play at 1000 ELO its very stong like 2000 ELO player not doing humen mystakes

I've been trying to get zappa mexico still working on it.

Analysis: Deep Rybka 3

Database: ChessBase Mega Database 2009

Tactics: Chessimo; Peshk@ with Convekta Chess Tactics for Beginners/Intermediate

Guess-the-move: Chess Hero

I agree with Shredder.  I recently purchased Shredder 12 for Linux.  Here is my review:

http://www.associatedcontent.com/article/2330314/shredder_12_for_linuxbased_systems.html?cat=15

its possible to play against a 1700 ELO engine for example playing like a humen but not doing a very good master game with blunders making this a stupid simulation?

Yea, Shredder can be "dumbed down" to match any rating :).  Many engines can.

dumbed down? sorry im not english to understand that you mean.

for example, chessmaster can do that but a 1600 personality on that program gives pawns away to be that rating but sometimes find a mate in 6 moves.

more engines do that and i dont like it

ps: chessmaster sucks

Deep rybka 3 destroys chessmaster 10.

rybka is just a engine and chessmaster is a beginners learning game with drills and tutorials. good way to start but not recommended for improvment.

I have yet to see an engine that can realistically impersonate a human player of a certain level. That's why I hate playing against programs that attempt to do that.
