I think that it is easy to prevent it by different time management against pablo. I do not see how pablo cause computer time loss if the computer has a rule not to use more than 0.1 seconds per move if it has at most 30 seconds to finish the game and not to use more than 0.1+(x/30) seconds per move when it has 30+x seconds to finish the game. The computer can also can has a rule to play faster when the opponent leads on time by substracting the time difference from its remaining time. Uri
