GilesFarnaby: <Knight13: <20. Rxc3> Is this what Kasparov had in mind? To trade off pieces and draw?>
20.Rxc3 was a moved played by Karpov, and Kasparov's reply (ie, to give back the exchange) is considered forced by both, as you can see for yourself in here: http://www.youtube.com/watch?v=63-M...
Kasparov criticised 11.d5, saying that is was too early to open the center in a favourable way; however, Garry spoiled his position soon afterwards, with 15...Nb6, a move that not only forces the Q exchange, if Karpov so wishes, but leaves the N in a dull Q-side with no plan. Garry suggested 15...Nf6 as much more active and accurate.
After the exchange sacrifice, and the counter sacrifice, Karpov said that Garry was afraid of being squeezed, even if white has no practical development in sight (but we know that Kasparov always hates passive positions...). Garry also spoke in favour of 24.Rc1 -more purposeful-, instead of the abstract Kg2 that was actually played.
After 42.Kxd3, the game was going to be adjourned, but Tolya felt that his opponent could perfectly study overnight a safe way to draw, so he offered to split the point, and split the point they did.
