|Chessical: A game in which it is again shown that White simply cannot mow down the French Defence on the K-side.|
Schottlaender had a long but absolutely winning line in <13... Bxh4!!>

He would have to calculate that he could allow White to take his Rook on <a8>
<14. Rh2> Qg5 15. Nf3 Rxf3 16.
Qxf3 Qg1+ 17. Kd2 Qxh2 18. Qxd5+ Kh8 19. Qxa8 Qf4+ 20. Kd1 Qxf2 21. Qh1 Bg5 22. Ne2 Bg4
Schottlaender is given a second chance at a win after Gunsberg's peculiar <16. Kf1?>.
There does not appear to be anything wrong with the obvious <16. Nxf8> Qxf8 17. Be2 Re8 18. O-O-O winning.
Having denied himself the exchange Gunsberg still believed he had the better game as he avoids <20.Ng6+> with a perpetual check.
Perhaps, he believed that in this complex position he was a better calculator of variations than Schottlaender, as he is prepared to risk his <d> pawn being taken by playing <18. Qg5>.
With the benefit of hindsight, and computer checking, we can see that <18... Nxd4> 19. Qxd5+ Qxd5 20. Nxd5 Rxg6 21. Nxb4 Rd6 would have been a serious embarrassment to Gunsberg.
In the end, Gunsberg overplays his hand on the K-side, and then blunders with <23.. Rh2> as <24.Rg2> allows Bf4.
