Against a dumb opponent, ve simulates the future game tree a few levels deep to figure out how to get the most points.

Looking at a few of the runs, it looks like DMRB vs SimHatingTitForTat results in both sides cooperating, until DMRB hits the last turn and defects. Which is fairly close to DMRB simply playing tit-for-tat against SHTFT, even though the latter is considered a "dumb" bot.

Yes, because if DMRB defected any sooner, then so would SHTFT, and DMRB would get fewer points in future.
