Recently, I have been playing the Urusov gambit (1.e4 e5 2.Bc4 Nf6 3. d4 exd4 4.Nf3) with White. The Urusov gambit seems dangerous if black accepts and if Black declines he usually gets into some very sticky situations.

?! This attempt to transpose into a Philidor is not such a great idea at the moment.

This is why the transposition into the Philidor doesn't work.

Oh dear, my knight is pinned but the position is beginning to look familiar to some of us.

Does anyone see what is coming?

? Time for Black to learn of Legal's mate. Really it is Legal's pseudo sacrifice since Black can't take the Queen without certain death.

! Everybody but Black saw that coming.

?? 5...dxe5 was the only move to avoid the prettiest mate ever.

First time I ever had the opportunity to finish with Legal's mate.
