Hi Steffen, >>"DarkThought" (http://supertech.lcs.mit.edu/~heinz/dt/) >>fails low on Qe6+ in iteration #12 after roughly 5 sec. >>It switches to Qg6+ instead within another second. > >Can you give me the PV starting with Qg6+? Does Qg6+ only delay the queen >exchange or does DT have a different plan? "DarkThought" follows a different plan and does not like to exchange queens here. The PV for Qg6+ in iteration #12 runs: 1. Qg6+ Kf8 2. Qf6 Kg8 3. Qg5+ It ends after Qg5+ due to hashing effects. But "DarkThought" switches to Qg5+ and then to e6 as the preferred move in iteration #13 anyway. It gets a deep fail-high on e6 with a score of >= +4.1 in iteration #16 later on after roughly 9 min. =Ernst=
