# mistake

can anyone tell me why this move (e6) is a mistake, the analysis shows a good line that followed if I played e5 instead of e6 , but that hardly makes it a mistake does it, just not the best possible move? 1. e4 c5 2. d4 cxd4 3. Qxd4 Nc6 4. Qc4 Nf6 5. Nc3 a6 6. Bf4 b5 7. Qc5 e6 8. O-O-O Bxc5 0-1

also if anyone knows how to go through analysis and see what the best moves are , I obviously can see the + - numerical value, is that the only way to tell or is there an engine which lists possible moves and rates them in descending order?

Are you looking at the board? 7...e6 is a mistake because there was a free piece waiting for you to take with 7...e5. 7...e5 discovers an attack on the queen and at the same time attacks  the Bf4, which is lost. 7...e6 does discover attack the queen, but the pawn on e6 doesn't attack anything, so White could have moved 8.Qe3 without losing any material

I hope that helps

PS: Just to be clear: Yes, 7...e6 is a mistake! You failed to take a free piece. Look at it this way: If you simply moved on of your pieces to a square where it could be taken for free, wouldn't you call that a mistake? Failing to take a free piece is exactly the same mistake. In both cases you are one piece worse off.

sorry I posted the wrong game , this was the one I meant to post , I am black 1. e4 c5 2. Bc4 Nf6 3. Qf3 Nc6 4. e5 Nxe5 5. Qf4 Nxc4 6. Qxc4 d5 7. Qxc5 e6 8. Qb5+ Nd7 9. d4 a6 10. Qa4 Be7 11. Bf4 O-O 12. Ne2 Nb6 13. Qa5 Nc4 14. Qc3 a5 15. b3 Bb4 16. Bd2 Bxc3 17. O-O Bxa1 18. Bc3 Bxc3 19. Nbxc3 Nd2 20. Rd1 Ne4 21. Nb5 Qd7 22. a4 Qc6 23. c4 dxc4 24. bxc4 Qxc4 25. g3 Qxe2 26. Rf1 Nd2 27.

Kf1 Rc2 0-1

disregard your right it must of been that first game , thx

ahaha . I'm confusing myself , the game I just posted is the game I am asking about , I moved the pawn to e5 revealing an attack on the queen and also protect the d pawn with a second piece allowing I hoped more flexibility, I do get that the pawn was already covered by the knight and e6 would have occupied the centre but is it really a mistake?
