| Chessical: A highly theoretical and tactical opening as Gligoric drives his central pawns forward. <25. Qxg6+!?> seems to lead to a draw after <25...Kh8> 26. Qh6+ Kg8 27. Bxc4 Rxc4 28. Qg6+ Kf8 29. Rd3 Qe6 30. Qh7; Gligoric obviously wanted more. He was counting on Smejkal miscalculating with an exposed King, but Smejkal defends steadily and it is Gligoric who eventually goes wrong in the complications. <26. Rxd5> Qf6 27. Rd7+ Kf8 28. Rxb7 seems an improvement over Gligoric's actual move.

<32... Bc6!?> 33. f4 and now <33... d4> 34. g3 Qf5 seems preferable to: <33... e4> 34. f5 Qd6 35. Qh4+ Kg7 36. Qg5+ Kf7 37. f6 By playing <33. Qe6+> Gligoric would have been almost equal, <33... Qg6> 34. Qe7 Bc6 35. f4 e4 36. f5 Qd6. His actual move <33. Qh4> relies on the Queen and the passed King-side pawns.
