Temperatures are below freezing round-the-clock, but are forecast to rise, bringing snow
FACED a German.

Mark Lamprecht (2155) - Spanton (1736)
English Symmetrical
1.c4 c5 2.Nc3 Nc6 3.g3 g6 4.Bf2 Bg7 5.e4 d6 6.Nge2
White has adopted a Botvinnik setup. which works best when Black has played ...e5 (Tony Kosten) or ...Nf6 (Andrew Soltis)

6...e6 7.d3 Nge7 8.0-0 0-0
Both sides have castled, reaching a position occurring 2,336 times in ChessBase's 2024 Mega database, but who stands better?

Stockfish16 and Komodo14.1 reckon the position is equal.
9.Rb1 b6 10.Be3 Nd4 11.e5!?
How should Black respond to this thrust?

11...Nxe2+ 12.Qxe2 d5?
Self-pinning is rarely a good idea, and this is no exception. After 12...Rb8 Black has the better side of equality, according to the engines.
13.Bg5 f6?!
Almost certainly a novelty, and almost certainly not a good one. Instead, after 13...Bb7, Black is not losing a pawn, partly thanks to pressure against the white e pawn.
14.exf6 Bxf6 15.Bxf6 Rxf6 16.Rbe1
White has the upper hand, according to the engines.
16...Rb8?!
Almost certainly better is 16...Bb7.
17.Qe5
Also strong is 17.cxd5 Nxd5 18.Qe5.
17...Nc6 18.Qg5 Ba6?
The engines give 18...Kg7, among other moves, but reckon White has the upper hand.
19.cxd5 Bxd3?
This makes matters worse, but the engines anyway give White a winning advantage.
20.dxc6 Bxf1 21.c7!? Qxc7 22.Qxf6 Bxg2 23.Qxe6+ 1-0
