ughaibu: Yes it does, provided (a) that we don't include the rule 11 that Fwiffo has mentioned, and (b) that white has at least one other piece that can stay mobile outside the black enclosure of the fortress.

The fortress is very easy to set up - easier than perpetual raichi. (For those that don't know what a fortress is, imagine the white king on f6 and a white guard on f5. These cannot be captured with the rules in their current state.) Keeping at least one other mobile white piece is IMHO much harder since he has no raichi threats, and when white runs out of moves he loses.

So in summary, I feel that a fortress draw will very rarely be an option anyway, though of course I yield to those who have much experience than me in evaluating that.
