port-mortem computer analysis of this vote chess game: http://www.chess.com/votechess/game.html?id=16495

 

I pick up the analysis with our 4th move:

4.e4.  Just as good as Rybka's preferred Nf3.

5.e5. Correct. Five moves in and we have already built up a decent advantage +.43@14.

6.f4?!  Rybka still likes Nf3 +.32@14.  Our move scores +.12@14.

7.Nf3.  Finally!  says Rybka.

8.a4?!  We launch a pre-emptive attack where we think the king is headed.  Rybka prefers castling, then goes to Nc3, scoring +.23@15.  our move scores just +.08@14.

9.O-O.  Correct.

10.g4!  Rybka has to look 10 moves deep before agreeing that g4 is the best move.  well played!

11.h3.  Correct.  The game is basically equal.

12. a5?!  Rybka scores Nbd2  .20@12. Our move leaves the game dead equal.

13. c3.  Just as good as Rybka's Be3.  The game is still dead equal.

14. b4!  Correct!  We find the right plan to attack the queenside, choosing to keep the center closed.  We have a slight advantage +.18@16.

15.exf6. Black does not find the right plan and blunders away the game.  We find the best move and are now winning! +2.24@16.  They chat "this is not good"...

16. fxg5. Correct.

17. gxh6.  Black continues to struggle and our advantage increases.  +3.70@12.

18. g5.  Rybka likes gastroc's decision to protect the pawn and keep black on lockdown.  +3.63@14

19. Bf4.  We wanted to stop e4, but Rybka looks to get queenside operations underway with Na3, scoring +4.14@12.  Bf4 is still solidly winning 3.99@12.

20. Qd2. Rybka still likes Na3 but our move is just as good.

21. Re1. Rybka is not worried about e4 and keeps the rook on the f-file Rf2, scoring 4.33@14.  Our move scores 3.95@14.

22. Na3. Correct.

23. h4.  Rybka goes for b5 and a queenside attack, scoring it +4.84@13.  Our move scores a solid +4.2@12 though, good enough for an easy win.

 

Black loses on time with Rybka recommending the ugly Qd8 as best...  yikes!

 

Black's comments for the last couple moves can be summed up as what should we do here?  and damn if I know.  They are totally trapped and waiting for us to finish them off when they run out of time.

 

Well played team!
