New Developments from Position 3!

New developments from Position 3: "Pressure compensation" position! : Posted to the Microsoft bulletin board @ Thu Jul 8 00:11:59 by Irina Krush and Ron Henley:

FURTHER ANALYSIS IN THE LINE 10...Qe6!? 11.Nd5 Qxe4! 12.Nc7+ Kd7 
13.Nxa8 Qxc4 14.Nb6+!? axb6 15.Be3:
Position code 12: "Pressure compensation" position
 
 
A) 15...Ra8 16.Nc3 b5!? 
Position 13
17.a3 Ke8 
Position 14
(with the plan of d6-d5!) 18.Bg5 
(18.Rc1 b4 19.Ne2 Qa2! 
Position 15
destroys White's queenside) 
18...Ne4 19.Nd5 
Position 16
(Is White coming around for second helpings with Nd5-c7+!? Instead 
19.Nxe4 Qxe4 20.Re1 Qf5, 
with advantage to Black, as the tactics 
after 21.Bxe7 Nxe7 22.Qxd6, are in Black's favor, for example: 
22...Qd7 23.Qxd7+ Kxd7 24.Rad1+ Ke8 25.Rd5 Bxb2 26.Rxb5 Bxa3 27.Rxb7 
Bd6, 
Position 18
and Black has a material advantage and excellent winning 
chances, as he can attack without risk.)

And now after 19.Nd5, 
(Repeated from above- Position 16)
Black has the interesting 19...Nxg5!? 
Position 19
A1) 20.Nb6 Qf4 21.Nxa8 Nh3+!? 
Position 20
(this is how they play chess in Latvia!), with:

A1a) 22.Kh1 Nxf2+ 23.Rxf2 (23.Kg1 Bd4, wins for Black) 23...Qxf2 
24.Nc7+ Kd7 25.Nxb5 Bxb2 26.Rb1 Be5 27.Qa4 Qf5, 
Position 21
and Black is clearly better.

A1b) 22.gxh3 Be5! 23.Kg2 Qxh2+ 24.Kf3 Qxh3+ 25.Ke2 Nd4+ 26.Ke1 Nf3+ 
Position 23
27.Ke2 Nd4+, with a DRAW by perpetual check. Instead, White should 
play: 

A2) 20.Nc7+! 
(Isn't that so funny? Same fork, different knight and 
different rook!) 20…Kd8! 21.Nxa8 Bxb2 22.Rb1 Bxa3 23.Nb6 Qc5 24.Qd3 
Position 25
(24.Qd5 Qxd5 25.Nxd5 b4, is good for Black) 
24...Nd4 25.Ra1 Nc2 26.Ra2, and now: 
(Repeated position: Position 25)
A2a) 26...Nb4? loses to the beautiful 27.Qxa3 Nxa2 28.Qa7!! 
Position 26
and White wins (but not 28.Qxa2? Qxb6
Position 27
, and it is Black who wins). Better for Black is: 
(Repeated position: Position 25)
A2b) 26...Qxb6! 27.Rxc2 (27.Rxa3? Nxa3 28.Qxa3, and Black wins) 
27...Bc5 28.Ra1, 

with an UNCLEAR position - Black has a BISHOP + KNIGHT + FOUR PAWNS versus 
TWO ROOKS. 

However, more SOLID for Black than the picturesque 19...Nxg5!? is 
19...Rd8 20.Rc1 Qd4, 
Position 29
with level chances, as Black need not fear an exchange of queens.

In summary 15...Ra8 is very sharp, and TACTICAL in nature. 

Instead, of 15...Ra8, a move which is more in keeping with my own 
personal style is 15...Nd5! 
Position 30
(likely best) - a move which is more 
STRATEGIGAL in nature, as the Black knight becomes CENTRALIZED. For 
example: 

16.Qd2 Nxe3,
Position 31
and now: 

A) 17.fxe3?! Ra8 18.a3 (18.b3 Qb4 19.Qxb4 Nxb4 20.Nd4 f5, is good for Black) 18...Ra5! 
Position 33
and Black has an edge.
B) 17.Qxe3 Qc5 
18.Qb3 (18.Qf3 Bxb2 19.Rab1 Bf6 20.Qb3 d5 21.Qxb6 Qxb6 
22.Rxb6 Kc7 23.Rfb1 Rb8, and White has not equalized) 18...e6 19.Rac1 
Qb4 20.Qf3 Ke7 21.a3 Qb5, 
Position 35
with an edge for Black.
