Pawn and Two: Carlsbad 1907 was a rough tournament for both Johner and Janowski.Johner started out with 9 straight losses enroute to a last place finish (+3-14=3).
After 1905, Janowski's tournament results show a marked decline. At Ostend 1906 he placed 8th (+13-11=6). At Nurnberg 1906 he was tied for last place (+3-11=2). At Ostend 1907 he tied for 3rd/4th (+9-6=5), but could only score +2-6=4 against Tarrasch, Schlechter & Marshall in this championship tournament. At Carlsbad 1907, he placed 15th (+8-11=1). At Prague 1908 he was 10th (+9-7=3), and at San Sebastian 1911 he was tied for 11th/12th (+4-6=4).
These were strong tournaments, but for Janowski to score under 50% (+46-52=21) indicates a marked decline from his best years of 1901-1905.
Johner's 21.Nd4? was a serious error. Fritz indicates White's best choice was either: (-.44) (23 ply) 21.Ne4 b4 22.Nxc5 Rxc5 23.axb4 Nxb4 24.Bb3 Ba6 25.Bc4 Rxc4 26.Rxc4 Rd8, or (-.45) (23 ply) 21.Rfd1 b4 22.axb4 Qxb4 23.Nd4 Nf4 24.Qg4 Ncd3 25.Nxf7 Ne2+ 26.Qxe2 Nxc1 27.Bxc1 Kxf7.
The new Carlsbad 1907 tournament book added a nice variation at move 24. After Johner's 24.Ngxe6, the game was quickly over. Instead, White should play 24.Bxd3 and after 24...Qxd4 25.Nxe6 Qd5 26.Nc7 Rxc7 27.Rxc7 Nh4 28.Rxb7 Qxb7 29.f3, the tournament book notes, <Black is better, certainly, but White is in the game.>
After 24.Bxd3, a better variation for Black may be, 24...Rxc1 25.Ndf3 Rxf1+ 26.Kxf1 Rd8 27.Be4 Bxe4 28.Nxe4 Qc6 29.Nd6 Nh4 30.Nxh4 Bxd6 31.exd6 Rxd6. At this point, Fritz shows a strong advantage for Black: (-1.45) (21 ply) 32.Nf3 f6 33.Nd2 g5.
