Czech Seniors Open Championship Round Three

LARGE sections of Olomouc's medieval walls have survived, partly thanks to the former German-speaking administration not wanting the city to expand by accommodating more Czech-speaking residents.





Here is my second game from yesterday's double-round.
Spanton (1852) - Zdislav Košťál (1646)
King's Pawn Irregular*
1.e4 c6 2.d4 e6!?
There are 279 examples of this move in ChessBase's 2022 Mega database, which dates back to at least the 1840s and was a favourite of the Rev John Owen.
3.Nc3 Nf6!?
Stockfish15 and Komodo13.02 strongly dislike this, preferring 3...d5 or 3...d6.
4.Nf3
This was grandmaster Stuart Conquest's choice in a a 2001 simul (he got mated in 13 moves). The engines like 4.e5!?, meeting 4...Nd5 with 5.Ne4.
4...Be7 5.Bd3 h6 6.Qe2 b5
The game's first new move - 6...d5 occurs in Mega22.
7.a3 Bb7 8.Bf4 a5 9.0-0 0-0 10.Rfd1 b4 11.axb4 Bxb4?
Black was in trouble anyway but is now almost certainly positionally lost

12.Na4 Nh5 13.Be3 Na6 14.c3 Be7 15.d5
The engines prefer 15.e5, but agree the text is also winning.
15...Bg5??
Best, but also losing, according to the engines, is 15...cxd5 16.e5!?, eg 16...f5 17.g3 g5 18.Nb6 Rb8 19.Bxa6 etc.
16.Nxg5 (1-0, 34 moves).
*ChessBase classifies the opening as a French Exchange Variation. It isn't.
