Subject: [usbca_chess] ...On The Attack!, (001)
Hello all,
Please, re-posting ...On The Attack (001), sent out on 02 August,, replace
that email with this copy.
The analysis for diagram 3 had some quite amusing mistakes, helpfully
pointed out by 2 students.
My excuse: Problem 1 was solved with the assistance of a glass of Shiraz.
Problem 2 was also solved with the assistance of a further glass of Shiraz.
Then the 3rd problem was similarly solved with the assistance of yet
another...
So here is a corrected version, apologies for any confusion with the earlier
email.
Since there are no coaching sessions during August perhaps a daily puzzle
might be some consolation?
Find below 7 positions from the games of Judit Polgar.
Diagrams, marked with double hash signs, are given in 2 formats, choose
whichever you find more convenient.
The solution with analysis is given with each diagram.

diagram.

| And black threatens an undermining, 14. ... Bxc3 15. bxc3 Qxb5, winning a
piece.
White to play must deal with this threat, right?
||
14. Rae1 Bxc3
15. bxc3 Qxb5
| Well there you go, white has lost a piece and surely blown the game,
right?
||
16. Qh6 Qf5
| It never rains but it pours.
White had a cute, "Master-Plan", of, Bf6, when giving up the piece on the
queenside.
Now that the black queen has come to the rescue of her Kingship, we expect

on, time to get working on the problem.
