{Black to move, white just played Bh5. }
{Second best is Nxf5 (-1.11), best is Ke1 (-4.49) }
1... Ke1! {Black is down a piece, but is winning due to the mating threats. }
{This simple king move tightens the noose around white's king. }
2. Ra1 {Ra1 is the suggested continuation from Fritz. }
{The actual game went like this: }
(2. f6 gxf6
3. gxf6 Rd2
4. Ra1 Rc2+
5. Kb1 Nf1 {and white resigned. If white tries Ne4 to stop the mate, then }
{Nd2+, and after the exchange on d2, Rc1# can't be stopped. }
)
2... Rd2
3. Kb1 Rc2
4. Ra3 Nf1
5. Rxb3 cxb3
