Very nice! There can only be one tactic, but it works nicely Smiley
Impossible to see in blitz with White's threat Nxf5

That remembers me of the position after 1.d4 d5 2.Nf3 Bf5 3.Bf4 e6 4.e3 Nf6 5.c4 (diagram):

Black was thought to have an easy life after 5...Bxb1 6.Rxb1 (6.Qa4+ Qd7 is possible but not necessary) since 6...Bb4+ forces 7.Ke2, but White has some backlash, e.g. : 
- 7...dxc4 8.Qa4 Nc6 9.Ne5 asks for trouble after 9...a5 (or 9...Nd5) and the thematic 10.Nxc6 Qd7, Black regains the piece but likely not for free 
- 7...Be7 8.Qb3 Qc8 9.g4! with initiative
- 7...Bd6 8.g3 Bxf4 9.gxf4 is likely Black's safer, but += by computer
So, not sure Black is threatening anything with this trick, maybe he should just play Bd6 instead of Bb4+ ?

A casual game from the club last night.
White "Amateur" vs Black "an ordinary chessplayer"

1.d4 d5 2.Nf3 Bf5 3.h3!?
What to do about this? I tried to ignore it.
3...e6 4.Nbd2 Nd7 5.c4 c6 6.c5 
That doesn't seem correct. I wasn't sure if 6...e5 was best but it seemed fine, so I gave it a go.
6...e5 7.dxe5 Bxc5 8.Nb3 Bb6
The engine prefers 8...Bb4+.
9.Bf4 Qe7 10.Nbd4 

Position after 10.Nbd4. I did black on bottom because it's a Reversed London.
FEN r3k1nr/pp1nqppp/1bp5/3pPb2/3N1B2/5N1P/PP2PPP1/R2QKB1R b KQkq - 5 10

Here the game proceeded 10...Be4 11.Ng5? Qb4+ -+
But when I turned on the engine it suggested a nice move for black in the diagram...

It seems like a random tactic, but not totally unrelated to opening theory. One can easily imagine this arising from 1.d4 d5 2.Bf4 Nf6 3.e3 Nbd7 4.Nd2 c5 5.c3 c4 6.e4 etc.
