It takes it a couple of minutes to find it at all on that machine, which is slow. Sometimes it finds it faster, and sometimes it has a better line right off. Your final line isn't the line that seems to be the solution. You want 1. Nxh6 c3 2. Nf5 cxb2 3. Qg4 at least, I think, in order to be on the road to a real tactical crush. You seem to have something turned up pretty high if you find a pawn compensation without really searching anything, and you are willing to play the key move after one second. Are you trying to change Junior's style? I run these every day at 5 minutes per, but I seldom look at the output, I just keep the stuff so I can compare later. Can you find the key in position 8? I noticed today that one of my versions had found it with a score of +0.5, I don't know why. That one is supposedly broken, according to DT, but perhaps it pops up if you speculate (or have bugs). bruce
