Always nice to have some interest in 'my' test suite.  I have been meaning to
revise it, but haven't found the time ... its quite a time consuming and
difficult exercise!  Perhaps this discussion will get me going.

I have quite a few emails about various positions saved (sorry to those who I
didn't reply to), there are of course some incorrect ones although some of the
ones you question here I hadn't had cause to doubt previously.

I assume you mean Ng2 here.  Care to provide analysis?  After Ng2, do you think
h3 or hxg3 draw?

Support the passed pawn with his King, then advance it.  If black wins the pawn,
whites king will be able to mop up the kingside.

Its from a famous game, you should be able to find analysis quite easily.

Passive defense is seldom good in rook endgames, I doubt this is an exception
although I haven't analysed Rb8 yet.

After analysing this with Dieter Buerssner I think we also came to the
conclusion that it is not correct.

After a quick '10 second' glance I suspect you are right.
