Gypsy: The star of the show is the White white-sq bishop and the game is rich in subtlety. Here is a few tactical finesses (of positional impact) I noted:
<12.Bxd5> The trick is that the tempting 12...Nxd5 13.Nxd5 Qa7 14.Nc7+... (13...Qa5 14.Bd2 Nb4 15.Qc4...; or 13...Qb3 14.Ra3...) puts Black position into a disarray.
<20.a5!> A key move. It separates Black pawns which, in turn, cramps Black lifestyle for many moves to come.
<23.Na4!> Black can not hold on to his twin bishops because the c5-pawn is too much of a liability. <23...Bxa4> at least brings on an off-collor bishops situation; 23...Bxd5 24.exd5 would bring on a terrible bind.
<25...Be7> Yet another place where I initially took a double take. Of course, the trick is that 25...Bd4 fails to 26.b4. Throughout the game, White weak points are always sufficiently covered and Black just can not find a toehold to mount a substantial shakeup.
<29...Rc7> Black pieces are stumbling over each other. Since it is typical that weaknesses easily trade against each other, one would assume that it would be fairly easy to either trade the Black c5-pawn for the White pawn on a5; or, at least, to tie down one White rook to the a5-pawn's defense. But, of course, if now 29...Bd8, then 30.Rxc5 and the rook also protects the a5 pawn sidewise. Sometimes, a player is just fortuous when good things like that happen. But in Burn's case it seems to be just as much a result of conscious design as a result of fortune.
<48.Kh5> White can collect the a-pawn (say, 48.Bc4). But, it seems, he judges it not worth the extra range for the Black rook (or of a rook trade).
<72.Bc4> A mate comes in just a few moves.
