From Staid to Chaotic

Starting out with a calm defense, the following game becomes more dynamic - and as the clock ticks down, play becomes more frantic...

1.e4 e5 2.Nf3 Nc6 3.Bc4 d6

The Hungarian Defense. Here, most Jerome Gambiteers would sigh and mumble "Maybe next game..." But not Philidor1792.

4.Bxf7+

We have seen this kind of a thing in "Philidor vs the Philidor". 

4...Kxf7 5.c4

Now, Black has to figure out what to do, how to arrange his defense. It is not unusual to see him protect the g5 square against incursion, but this will come back to haunt him.

5...h6 6.d3 Nf6 7.Be3 Be7 8.Nc3 Rf8 9.Qb3 Na5 10.Qa4 c6 11.Qc2 b6 12.O-O Kg8

Except for his offside Knight, Black does not seem to have suffered
from the gambit - but, too soon, he relaxes.

13.Rac1 Bb7 14.b4 d5 15.bxa5 dxe4

Surrendering the advantage. Instead he had 15...d4 16.Bd2 dxc3 17.Bxc3 Nd7 18.Nxe5 Nxe5 19.Bxe5 c5. 

16.dxe4 b5 17.cxb5 cxb5 18.Qb3+ Kh8 19.Nxe5 Kh7 20.Qxb5 Bxe4 21.Rfd1

Possibly better was 21.Nxe4 Nxe4 22.Qb1 Qd5 and now the acrobatic 23.Rc4!?.

21...Qe8 22.Qxe8 Rfxe8 23.Nxe4 Nxe4 24.Rd7 Bf6 25.Nf3 a6 26.h3 Rab8 27.Kf1 Nc3 

28.Bd4 Bxd4 29.Nxd4 Nxa2 30.Rcc7 Rg8 

Time is so short that both players miss 30...Rb1+ 31.Rc1 Rxc1# 

31.Ne6 Kg6 32.Nxg7 Rb2 33.Rd6+ Black resigned
