When I ran this, I got +3.5 or so. On Rd1 my score gets significantly worse. Which simply means that they probably searched the alternatives deeper than I did and found that they were bad also. If you look at their log for game 1, Rf5 was best until the last iteration, where it failed low. It found two alternatives, Rg8 and Rd1 on fail highs, but ran out of time before it could figure out which was better. They chose Rd1, which they had computed was better than Rf5+, but it might not have been as good as Rg8 after more analysis... Their logs help quite a bit here in trying to figure out how/when a particular move was chosen. > >Engine: SOS 11/2000 >by Rudolf Huber > > 7.01 0:00 -1.11 1...e3+ 2.Ke2 Rh5 3.g7 Rh2+ 4.Kd3 Rd8+ 5.Rd4
