Re: Kasparov Said So... - Test Position
It is possible that Be7 be better, but it is hard to figure. There are some transpositions possible too, like: 1 ...Be7 2. h4 Rxc3.Dann Corbit wrote:The strong engines I tried liked Be7. So I forced the rook sacrifice and examined the resulting position:Marc MP wrote:[d]2rqkb1r/1b1n1ppp/pn1pp3/1p6/3NP1P1/2NBBP2/PPP2Q1P/1K1R3R b k - bm Rxc3; id "Movsesian - Kasparov, Sarajevo 2000";
I quote from "Secrets of Chess Intuition" by Beliavsky & Mikhalchishin: "Kasparov said that sacrifices such as this do not demand any calculation, and that by allowing it Movsesian showed that he did not understand the position well."
Will your favorite engine play this move?

Against a human the sacrifice may be better because of the pressure of opening the King's can and an enemy queen in the neighborhood.Code: Select all

I ran a tourney from the position after 1... Rxc3 2. bxc3 Qc7 (as played by Kasparov) at 50min+20sec on my prentium. That is:
[D]4kb1r/1bqn1ppp/pn1pp3/1p6/3NP1P1/2PBBP2/P1P2Q1P/1K1R3R w k - 1 1
Even if the engines don't want to play Rxc3 at once, they still play the position well and white scored only 43% as we can see from the opening report. Maybe this is a kind of position where the monte-carlo analysis will be helpful.
