The Game Corner: Ebb and Flow
This game was submitted by Zack R. for analysis. Thanks Zack. 1. d4e6
Anytime you can develop your
pieces and force your opponent to move back, it is advantage YOU!
Black is up .2 of a pawn
positionally. Or (-.2). When White has an advantage it will be shown as a (+).
The double move
of the bishop puts Black down (+.5) positionally (half a pawn). Simple mistakes lose chess games
After Black's move 11. ..... g5
Black voluntarily opens up his
King side for a pawn storm, but with no support from his army. All of Black’s
pieces are sitting at home cramped together. Now Black is down (+1) - with the
correct next move, that is.
12. Ne4 ……..
Wrong knight – Ne5! Is the move.
Black’s last move
chases White’s rook to a better square. (+1.5)
move of Nf6 was needed. Then after 16. Bxb7, you have Rb8 followed by 17. …….Rxb2 and
Black gets the pawn back with a dangerous rook in enemy territory. Black would
be down (+1.3) instead of (+2.6) with the actual move.
A passive move by White and a
strong move by Black makes the positional advantage wither to (+.6). The
energetic c4! - drives the advantage to almost (+3) for White!
Black retreats when the offense
he wanted on move 11 can now materialize. The Queen has entered the attack
zone, the knight and bishop are poised on good squares – and both Black rooks
have semi-open files to control (g and h).
Black gets back in the game after
20. ….g4!, 21. Qe3, gxh3 22. d5, e5 23. Bxe5, Bxe5 24. Qxe5, Qxe5 25. Rxe5,
Nxg2, - and White is only up (+.4) positionally.
The final losing
This is why
chess is such a great game. There was lots of back and forth of advantage in
make bad moves, but didn’t seem to find any “good” moves, and that would let
Black back in the game. If Black had stayed aggressive and looked for
opportunities, the outcome might have been different.
This is a good
game to play over to try and understand positional advantages such as;
Your opponent is
Lost tempos by
double moves by the same piece
Gained tempos by
opponent ‘forcing’ your pieces to better squares, or developing while making
your opponent back up
opponents back ranks
made by unsupported pawn advances
Many pieces near
or directed at the enemy king
Open and half
open files rooks can easily get control of
