VC - Serra - Engine Analysis

VC - Serra - Post Mortem

http://www.chess.com/votechess/game?id=30922

The engine used was Toga II included with SCID vs PC. Toga II can be beat by humans.
Numbers in braces {+x.xx} are the engine's rating of the position after that move is made, shown in percentages of a pawn. Ratings are generally based on material.
{+0.87} means the position after the move is made favors White by 87% of a pawn.
{-0.87} would mean the position favored Black by 87% of a pawn.
This game never favored Black
When two values are within the brackets, it means there was a better move than the move actually made, and that move and it's line are shown in parenthesis ( ). Only the engine's first choice is shown. These parameters are chosen by the engine, not by me.
The interpretation of these values is up to the human. Engines may give different results when they are allowed to run longer. Mostly these values are at a depth of approx 12 half-moves.
Engines cannot and do not know how to plan sacrifices nor can they see one coming.

Actual game moves are in bold.

Hi,

I am not sure about our 4th move, is there a reason why we not played Nf6,Nc3 with the tigers idea a6?!

@humans1981 - you can review the archives of all VC games to see what we said about the move. Here is a link to move #4 of this game.
