Analyze

Tips

• Use engine that displays several thinking lines at once. This way you get not only the best move, but also a list of possibly equally good moves.
• Use engine that displays 2-depth best move. Sometimes this helps to better understand why a given move is good.

General game

Online

• http://en.lichess.org/paste

Excellent. Very fast. Easy to browse, play variation, etc. Also local computer analysis.

• https://nextchessmove.com/

Enter a position and ask to get the next best move. Based on GNU Chess and Stockfish engines.

Android

• DroidFish

Powerful and easy to use chess engine, with clear analysis. Show 2-depth moves with green/red arrows.

• Chess Analyze This by Asim Pereira

Awesome game analyzer, with indication of blunders, bad moves. Analysis takes quite some time though.

Endgame

• http://en.wikipedia.org/wiki/Endgame_tablebase

Online

• Endgame database on shredderchess.com

Easy to use endgame database (6 men or less).

• Analysis board on lichess.org

Very powerful analysis board, including complete endgame database. Position are encoded in the URL (e.g. https://en.lichess.org/analysis/8/8/5k2/8/8/2P5/3K4/8_w_-_-)

Android

• Lomonosov Tablebases

Probably the best endgame browser out there. Perfect endgame analysis, up to 7 men. Offline DB for 3 men, more require network access. Pieces can be moved around, and the score for all possible positions on the board are shown on the board itself, which is very useful to analyze alternate positions.

Using Stockfish

Use stockfish from the command line [1]:

stockfish
position startpos moves e2e4
go depth 10
...
bestmove b8c6 ponder d2d4

Stockfish will reply with the best move for black (Nc6) and best counter play for white (d4).

Tips & Pits

• (Frequent mistake) In start position, b2 and g2 are only protected resp. by Bc1 and Bf1 → move these Bishops only if these pawns are not threatened / protected by other pieces!
