Does waiting for d4 (h5, c3 h4, d4 e5xd4, c3xd4 h3) produce a better tempo?  It seems the better choice to me, but I'm not sure.  It ends the same, but the black king and queen has a better position?

Thanks.

I don't know what you mean by waiting for d4.  The d-pawn will sit waiting for the black e-pawn to advance to e4, then capture it.  If black initially moves his h-pawn, White King moves Kd5 and has a clear line to block promotion at h1; it is then too late to block it by moving pawn to e4.

And in my case black got a poor position and checkmate ))

But 4. ...   Kd8  prevents white from promoting.

• #107

Easy

• #108

Why not 1...h4? I don't see why Black has to give away a pawn.

• #109

easy

that was fairly easy, but it was a good puzzle.

Because the White King can make a run for the corner and catch the pawn. But after the move actually played, there's either a White pawn in the way of his own King, or (if White doesn't take) the centre pawn is queening instead.

Chess geometry is a very interesting topic.

Today's problem reminds me of the following classical study of Richard Reti:

Black has to move twice with the king in order to prevent White's pawn from queening- and these are sufficient for White to catch the pawn. Here, after 1... e4 2.dxe4 White needs another two moves to create a threat to queen himself, so that Black has to move the King once.

Here, after 1... e4 2.dxe4                  You mean in todays problem!
