- Robert and I were friends at the
- Purdue Chess Club.  Our ratings
- could not have been more mismatched,
- but Robert gives the game a good
- fight.

-
- The most popular opening of the 19th
- century was to play the Evens Gambit
- with b4!? now.

- Attack the pawn that can not be

-
- Everything is book so far.
-  Sometimes White plays a gambit
- with 7. Nc3, but BCO2 prefers the
- following move.
|
12
[Next] |
-
- If now Black plays Nxe4, White will
- get advantage with 8. Bxb4 Nxb4
- 9. Bxf7+! Kxf7 10. Qb3+ d5 11. Ne5+
- Ke6 12. Qxb4 and Black has not
- only
- lost the extra pawn but the right to
- castle too.

[Next] |
-
- Now Black can get an equal game after
- playing d5!, as that gives Black more
- room and forces White to get an
- isolated center pawn.
|
15
[Next] |
-
- Everything was book until Black makes
- this error which leaves him cramped.
|
16
[Next] |
-
- This is the move I felt was critical
- here.  Although it costs a tempo,
- it gives the Black c8 Bishop no where
- to move, and as a result makes it
- much harder for Black to free his
- game.
|
17
[Next] |
-
- It is questionable for Black to put
- his Queen on the e-file as that file
- could easily be opened, and the Queen
- could then be attacked by a Rook.
-  But it is hard to see how Black
- can develope his pieces any other
- way.
|
18
[Next] |
-
- White has a plan of bringing his Rook
- to the e-file and pushing the pawn to
- e5 so as to attack the Queen....
|
19
[Next] |
-
- Black castles.  He is still
- cramped and doesn't have a good place
- to put the c8 bishop.
|

-
- Black proves that he is a Class D
- player by making a simple tactical
- error.
|
22
[Next] |
|
23
[Next] |
-
- Black figures that if he must give up
- a piece, then it should be the
- Knight.  I am not sure that it
- matters, as he is now lost either
- way.
|

-
- Just because White has won material
- doesn't mean he should give up on his
-
- plans that he made earlier.....
|
26
[Next] |
-
- ... pushing e5 hoping to open the e
- file and put pressure on the queen.
|
27
[Next] |
-
- The Knight can be too easily attacked
- on this square, as White is ahead in
- development, material, and space.
-  But moving the Knight to d7
- loses material after e6!, so the only
- safe square is to undevelope the
- Knight to e8.
|
28
[Next] |
-
- This is not a good move as Black CAN
- DEAL WITH IT EASILY.  Instead
- Nd2-e4 would have increased the
- attack on d5 while threatening to win
- a pawn on d6.
|
29
[Next] |
-
- Black should have played Nb6 which
- brings his Knight to safety and makes
- the Queen on b3 look misplaced since
- then if Rd1?? Ba4!
- Instead, WALKING INTO A PIN is almost
- always a terrible idea.
|
30
[Next] |
-
- This is very forcing, but Nd4 might
- also be interesting.
|
31
[Next] |
-
- Not much choice as the queen was
- attacked.
|
32
[Next] |
-
- The knight actually wants to go to c3
- to put pressure on d5.
|
33
[Next] |
-
- The queen has to continue to guard
- the d5 knight.
|
34
[Next] |
-
- Adding pressure to d5.  Now maybe
- Ba4 would reduce Blacks additional
- material loss down to a pawn, but at
- the cost of trading several pieces.
|
35
[Next] |
|
36
[Next] |
-
- White puts yet another attacker on
- the Knight.
|
37
[Next] |
-
- The knight is lost so Black makes
- desperation moves.
|
38
[Next] |

[Next] |
-
- Now the easy way for White to win a
- pawn is with Bxc6, but I chose a
- prettier finish.  White can also
- win material with 21. Ne5 or 21.
- Be4!, but I prefer the moves below as
- it brings the game to a quick
- conclusion.
|

[Next] |
-
- Check.  Because the queen is
- attacked as well Black must play ...
|
41

|
42
[Next] |
-
- Exchanging queens.  No good now
- is Rxf7 because d8 will drop, so ...
|
43
[Next] |
-
- He must take with the king.
|
44
[Next] |
|
45
[Next] |
-
- All of Black's responses have been
- forced.
|
46
[Next] |
-
- With this fork White gets his
- sacrificed piece back.  Soon
- pawns on the queenside will start
- dropping.  Here Black throws in
- the towel.
