Gandalf after 13 hours and 47 minutes still consider 1.Bxh6 as best but it did not finish iteration 15 so it may change its mind. 2)It is possible that Gandalf can find 4.Bxh7+ if I give it enough time and I did not check it. 3)I believe that most programs can find 4.Bxh7+ and only gandalf has problems to find it because it likes the white bishop too much. > >Could you post the Gandalf game you observed ?
