Attention please

I was up early this morning for some online blitz chess and one of my games arrived at the position in the first diagram with my Black opponent to play his 14th move. As you might guess this is a ...Nf6 Caro-Kann that has gone somewhat badly for White. I had been expecting to get mated in short order but when my opponent did not find a way forward I was suddenly able to turn things around:

14...exd4 15.Nxd4 Bxe2 16.Rxe2!
At first glance 16.Nxe2 looks safer but Black has 16...Nc5 after which White is struggling to stay afloat; for example, 17.Qc2 Qf3+ 18.Kg1 Nd3 and now 19.Rf1 loses to 19...Nb4.
16...Bc5 17.Qf3!
The defender's tactical operations must always be accurate. Here White is able to protect his rook and simultaneously attack Black's queen. This allows him to meet 17...Qxf3 with 18.Nxf3, getting his knight off prise. But Black can make a counter-threat of his own.
Threatening mate in one and renewing the attack on the knight.
White has survived the first wave of the assault but he must stay alert because h2 is a natural target for a mating attack.
Due to inertia Black continues to make attacking moves but it was already time to think about consolidation with 18...Kb8. After 18...Rg6 we have arrived at the second diagram, a position where White's pieces have stumbled onto good squares...
A somewhat fortuitous tactical resource but perhaps a thematic one after all. Black's king is also vulnerable!
If 19...bxc6 20.Qxc6+ Kb8 21.Bf4+ Ne5 22.Bxe5+ fxe5 23.Qxc5 Rh6 24.f3 and White must be winning easily.
Also possible was 20.Nxd8.
20...Kb8 21.Nxg6 hxg6 22.Qxe3 Rh8 23.f4
White has now consolidated his advantage. Black's position is pretty well hopeless and he was forced to resign a few moves later.

Frank Marshall once wrote that attention is more important than concentration in chess. The course of this game helped me understand what he meant.
