PART 1 • What you can expect to see after a game analysis
Black blunders badly at move 20: After the move 20.Bxd5, White's Bishop
is attacking Black's a8-Rook. But Black overlooks the attack and moves
his other Rook instead. The evaluation goes from being about a pawn
in Black's favor (-0.92) to being almost two full pawns for White (+1.95,
because White wins the exchange of a minor piece for a Rook), a net
swing of almost three pawns! But White blow it, fails to take the Rook,
and Black escapes...
What the analysis of this game says to me (and should say to both players
if they were to have Houdini analyze it themselves) is that both players
need to work on their tactical and visualization skills. Neither player is
likely to see the exact position after 20.Bxd5 ever again in their respective
chess careers, but they could both easily encounter a position very much
like it. The ability to recognize similar patterns is an important chess
skill which every player needs to develop; when a Bishop is suddenly
centralized in their future games, both players should remember this
game's analysis and think to check for any sudden attacks which that
centralization move has created.
Specific moves suggested by a chess engine in specific positions
aren't as important as what the numbers and the general nature of the
suggested move point out to us.
