  JonathanJ: is 21. rhg1 simply a blunder? there are other ways to avoid the fork!
Jun-23-09  centralfiles: is 7...o-o sound?
if it isnt then black should not play 5..Bc5 a move which has been played often
Jul-21-09  centralfiles: 15.Nfxd5 should put white way ahead
the immiediate 10..Qxf6 is more accurate as it avoids Nf4(fxg7 is good for black though i.e. 11...♕h4
12.♘xd5 cxd5
13.♗xe8 ♗g4
14.♗xf7+ ♔xg7
15.♕e1 ♗e2+)
Feb-24-10  centralfiles: wish there was good analysis on this one
May-19-11  centralfiles: Upon further investigation Black has a nice improvement 12...Qh4!

13.h3 ♘e2! is excellent for black.
13.♗e3 ♖xe3! is crushing.
13.♗d2(covering e1) ♗g4 14.g3 and Black is at least okay.

So now that 10..d5 11.♘f4 ♕xf6 12.d3 is no problem for black, and 12.♘cxd5 cxd5 ♘xd5 ♕h4 looks fine as well, we can conclude that 10...d5 is justified and black need not prevent 11.♘f4 with ...♕xf6.

May-19-11  centralfiles: There are many beautiful sacrificial combinations possible in variations of this game after white accepts the knight sac with 8.exf6. (declining with 8.O-O Ne8 is probably at least equal)

The following is just one example of an aesthetically beautiful puzzle:

11.♗b3 ♕xf6
12.♘a4 ♘e2!
13.♘xb6

Black to play 13...?
Medium/easy

Anyone taking up the challenge?

May-20-11  David2009: <centralfiles> Thanks for posting this beautiful and very worthwhile variation as a puzzle, solved by User: Phony Benoni in today's POTD Short vs Kasparov, 1993 - I am giving the link only so as not to spoil other people's solving pleasure.

As a postscript: I missed it. I spotted <PB>'s key move but not the fact that the move did anything useful or threatened anything - see <PB>'s comment for what it threatens.

Mar-12-12  centralfiles: Thanks <David2009>
Its nice to see that people enjoyed the puzzle as much as i enjoyed posting it (well...almost lol)
