It may be interesting to test both programs to find how much time they need to avoid Rd1 and how much time they need to find c5 in order to see if Comet is better in tactics than palm tiger or the opposite. I believe that 120/40 was not enough but that they are going to find the right move after enough time. The position is not so easy for computers and I bet that a lot of amatuers are not going to find c5 on p200 at time control of 120/40. movei seems to be one of them. Uri
