Re: A very complex tactical position
It's not obvious frankly. My first instinct was Rxf7 though it would need quite a bit of careful calculating to be sure. Rf6 really looks best though. Anyhow, here is Rybka 2.2 WinFinder on a slowish Athlon64:Terry McCracken wrote:The mark of a good player is knowing the best move without having to calculate everything.YL84 wrote:if the first move(s) are easy, you can exercise you to calculate the complete combination lines... It is less easy and there are some hidden threats maybe for blacks (Qc6 in some lines maybe). Doing a sacrifice during a real game is never easy !

All the Greats would agree.

Re: A very complex tactical position
The output is beautiful to me. It shows the whole plan for each layer, and many other important details. It is not clear that Rf6 is better than Rc2.Terry McCracken wrote:It's hard to decipher that much computer output....Rxf7? is inferior, Rf6!! is best.Dann Corbit wrote:I don't understand why you think that computers are stupid.
Rc2 and Rf6 are both better than Rxf7. Or do you imagine some other move?
I don't think that they are smart, but I know that they analyze better than I do. I have found that in certain complicated positions, the best programs can come up with moves that are very Morphy-like.

Re: A very complex tactical position
Several strong engines, given two hours seem to rank Rf6 and Rc2 about the same. The engines were given 2 hours and 512 MB RAM on 2.2 GHz AMD Athlon.
I would have played Rxf7 because the king pressure is obvious and I was not able to see deeply enough that it is not the best move. Both Rf6 and Rc2 seem obvious after you have played through the variations, but I doubt that I would have preferred them over Rxf7 in a game. I think that is one reason that I enjoy chess. I can see that the top of the game is over the horizon for me and so it includes a lot of discovery.
