Beware, harder than it looks !

Find the game that ends 5.Ng3 mate

Before you ask, the solution is unique, it's orthodox chess, and the word "mate" means checkmate, not "my friend" ! 😀

judging by the 5.Ng3 i would assume its white who mates yes? and it is played like a proof game

1. e3 e6 2. Be2 Qf6 3. Kf1 Nh6 4. h3 Nf5 5. Qe1 Ng3#

As hurricane conway pointed out it's white hwo mates !
Bsides there are duals (not unique solution) in yours, but nice mate anyway !

1. e3 e6 2. Qg4 Ke7 3. Ne2 Kf6 4. Qxg7+ Kf5 5. Ng3#
{White mates} 1-0

Now the tougher one: a game ends with the move 5. ... Rh1# (exact notation - no capture). How did the game go?

Those are nice puzzles. Anyone knows more like these?

In addition to that thread, there's the one that stumped Kasparov:

White starts 1.e4 and the game finishes with 5...NxR#

I wonder why Kasparov is 'always' mentioned in relation to that problem - is he such an expert on solving this type of problem then, I never heard of a fiendishly difficult problem with the addition that 'Kasparov solved this in under 1 minute'.

If Kasparov solves a problem in one minute, he is only doing what he is expected to do. If he fails, on the other hand, the solver is enticed with the notion that he can do something in chess that Garry Kasparov can't.

'he is only doing what he is expected to do'

Yes, that was my concern, I mean, has Kasparov solved that problem 'series selfmates in forty-two moves' in a minute? (I guess he hasn't, perhaps he hasn't even seen it, no-one knows)

"Series selfmate in 42" sounds scary. "Black mates on the 5th move" sounds innocent.

I think most people just assume that Kasparov can solve most chess problems without realizing that solving is a somewhat different skill than playing [with the degree of difference depending on what type of chess problem is being solved].
