Re: Vote for Fritz 17 Replacement

None of the above. I think Deus Engine will replace Rybka, aka better known as Fat Fritz.... :) :) I think so too. Why should chessbase give two engines with one sale? :) Earnestly, Fritz will be DeusX and Fat Fritz will be LC0 (or Deus) on chessbase- hardware like it is already now. And then the o...

Re: Winning after Qf6+!

I am confused. If I didn't miss something from this thread, After Ng5 of white, both Nxd4 and Nd6 (on Nxa3 line) of black was already posted by Peter and both ends up in a win. So IMO, both Ng4 and Bd2 wins for white. No, Mike, you missed Louis' fortress- line after 26...Nd6 (!) which I had to be s...

Re: Winning after Qf6+!

Peter, is it easy to see where this line deviates from the line you previously had in this position that seemed to draw? (I don't think you posted it.) I didn't. I made the once and always main mistake to look at an output only without playing it out and having some Forward Backward with it. The on...

Re: Winning after Qf6+!

Qf6+ is best move , but it's just a draw after doing an overnight search with about 1.4 trillion nodes searched. Maybe if somebody searched 100 trillion nodes, they might find something different. That would require dually epyc processors for about a week. Some quick 5 min analysis dep score nodes ...
