19...b5 $2 {Too naive.}
(19...Rfe8 {was more solid, but White is still in control:} 20.Qg3 $16)
20.f5 $1 {Powerful and precise. Black cannot allow this Pawn to go to f6 so the intruder must be taken.} 20...exf5 21.Rxf5 Qb6
(21...gxf5 22.Qxf5 {leads to unstoppable mate in a few moves as h7 cannot be defended.})
(21...f6 {was by far the most tenacious.} 22.Raf1 $1 gxf5 23.Bxf5 Rf7 24.e6 $18 {is very ugly but this was as good as it got for Black.})
22.Qh6 $1 {Now White threatens Rf5-h5. In some lines the move e5-e6 also comes into play.} 22...gxf5 23.e6 Nf6
(23...f6 24.Bxf5 {and against the weakness of h7 tells.})
24.Qg5+ 
(24.Bxf6 Bxf6 25.Bxf5 {was also possible.})
1-0
