Bad Wiessee (part four)

Spanton (1878) - Ludwig Wawrinsky (1771), International Seniors' Cup, Round 5
1.e4 e6 2.d4 b6
This might be an OK surprise-weapon, but in the age of databases it has to stand on its intrinsic merits.
3.Bd3 Bb7 4.Nf3
Having said that, one advantage of systems like this for Black is that Black will almost certainly have much more experience than White of the resulting positions,
I had done some prep, but LW's next move was not one that I knew he had played before; then again, it is hardly a game changer.
4...h6
I was surprised to discover from ChessBase's 2018 Mega database that both Kasparov and Short have had this position (as White, naturally).

White to play in a position that has faced both Kasparov and Short

There are 101 games with this position in Mega'18.
5.Nc3
Most popular, occurring in 53 games, is Nigel Short's 5.0-0.
Garry Kasparov's choice of 5.c4 is third most-popular, occurring in eight games.
The text occurs in just four games, but White has massive percentage scores from all three moves.
5...Bb4 6.Bd2 Nf6 7.Qe2 a5?!
I thought this might be to dissuade me from castling queenside, although I was far from sure Black needed to be worried about such a possibility.
8.0-0 Ba6
But I guess the reason for White's seventh was that LW was planning to exchange light-square bishops.
9.Rad1 Bxd3 10.Qxd3 0-0 11.e5 Nh7 12.Rfe1
LW now came up with a move that I do not think would have crossed my mind in a proverbial month of Sundays.

Black to play a move that, while tactically not unsound, is a positional shocker

12...c6?
The game finished:
13.Ne4 f5 14.exf6 Nxf6 15.Ne5 Bxd2 16.Rxd2 Nxe4 17.Rxe4 Qf6 18.Qg3 Kh7 19.Rd3 d6 20.Rf3 Qe7 21.Rxf8 dxe5 22.Qf3 Qb7 23.Rxe5 Nd7 24.Qe4+ g6 25.Rf7+ 1-0
With the game over before noon, I set off for a walk around the lake of Tegernsee beyond Rottach-Egern and on to the town of Tegernsee.

Schloss Tegernsee

It was easy to spot Schloss Tegernsee (English: Tegernsee Castle) as I walked around the lake, and I assumed the building must be modern as even from a distance one can see it was not built primarily for defence.
In fact, it was begun in the eighth century as an abbey, and has been much modified over the centuries. It was secularised in 1803, became a brewery for a short time, and in 1817, according to Wikipedia, was bought by the King of Bavaria. The abbey passed into the hands of a side branch of the ruling Wittelsbach family - Bavaria is dotted with Cafes Wittlesbach and Hotels Wittelsbach - and was renamed Schloss Tegernsee.
The current owner is the 81-year-old Prince Max, who is head of Bavaria's now-former royal family and is also, if you believe in the Jacobites' King Over The Water, the rightful monarch of the United Kingdom of Great Britain and Northern Ireland.
