even i hope somebody post with a good reply, i am also looking for one
chess analyser

Just get SCID on the go for Android. You can insert PGN's and analyze them with Critter chess engine.

Yup. Got Scid. Good too.
But will someone tell me how to understand the analysis. The moves keep on buzzing around and i dont get a clue

The moves 'buzzing around' are the engine calculating the probably continuation. wait for around 30 seconds until it settles on a certain line and then play through that line.
Hi. I need a chess analyser which will analyse my games and tell me where i lost advantage and possible alternatives upon inserting pgn. The chess.com analyser is good but i only get 1/week. Something similar like this online or free downloadable for android is required. I want analysis of my games , not a particular position.
Thnx.
Eagerly awaiting replies
