Ruffian as UCI would calulate everything from scratch, losing a lot of time. I don't know how big the elo-difference is, but such a failure would hurt, for example, Junior badly. After a couple of days I let you know if Ruffian plays better now. I am happy if Ruffian doesn't lose on time anymore. Nevertheless I know there might be a bug in Ruffian timemanagement overall. Tuesday the Ruffian 2.1.0 is expected. Kind regards, André van Ark
