Thou gotst that right!

Should white have resigned?

 

Not yet. Black's threatening mate in 1 with Nf2 as well as taking the Bishop. Since white can't stop that Knight move, he can provide his King with an escape square AND protect the Bishop (his double dilemma) with h4, after which everything seems pretty nclear to me.

Batgirl, thanks for the additional annotations. Great question, and nice response regarding 9.a4. I sort of touched on it on move 10, but it was after the fact. Your explanation is clearer. I feel bad when I annotate Fischer's games or any GM's because you cannot really "explain" all their thoughts. First, because I don't believe I am good enough. Second, I need the help in the areas I miss or overlook - (so thanks for that!). Lastly, people with some training will be able to see other things that the annotator didn't include.

I really liked 20...Ng4!

For some reason nobody has tried to answer my question, whether White should have resigned or not! 

Move 9....a5.

What do you see as the purpose for that move? Black starting a counter-attack on the queenside seems to be halted with white's 10. a4. Was this a book move in 1956? Now we know that pawns can't go backwards, so I would think Fischer saw several things that justified pawn pushing in the opening phase. One, white would have to play a4 to slow a queenside pawn storm, removing one of the knight's defenders, so when he played ...Be6, the move would have more force, but even more, he forced a situation where white received doubled pawns and he created an instant outpost for his knight... all with this one simple pawn move.

 

15...Rac8 does x-ray c2. Good obsevation! Material is even, white had the bishop pair, yet black, at this point, has a virually won game. Go figure.

 

20...Ng4 - unpinning with a vengeance.

 

Great game. Great annotations.

Merci beaucoup.

I agree. He must have seen all the moves prior the Queen exchange.

Fischer's manoevering of his queen knight was exquisite
