But there was one point of interest before Tinsley's 14...Nxf2?

Maroczy tried the Advance Variation (3. e5) against Tinsley's French Defense, got the better game after Tinsley's poor 6...Qc7 (6...fxe5 would have been much better). But Maroczy then misplayed the balance of the opening. His 7. exf6 (instead of the better 7. 0-0) brought Tinsely's Knight to f6, the square the entire line was seemingly designed to prevent. Maroczy followed up this error with the very weak 10. Nbd2 (he should have prevented Tinsely's plans with 10. h3), and then misjudged the position with 13. Qc2 (he was already worse, but 13. Bd2 was best).

At this point, Tinsley could have tried the superficially awful but actually brilliant 13...Qb6!! This move allows 14. Bxh7+, but after 14...Kh8 it is amazing how fast White's game deteriorates. Probably best for White would now have been 15. Be3, but after 15...NxB 16. fxN Rac8 Black has all the play.

Perhaps best of all for White after 13...Qb6!! would have been 14. Ne3, but Black would clearly then have the better game.

Instead of this fascinating move, Tinsley played the craven 13...h6, and then tried to make amends with his unfortunate sacrificial combination beginning with 14...Nxf2.

Tinsley was probably lost once he made his 14th move, but just to be sure he blundered with 18...Bf4 (as the Tournament Book points out, 18...Rf6 was essential), with 21...Qe5 (if he wanted to continue, he had to try 21...Rg8), and then with 22...Qh5 (23...Qd6 was "best" here) and with 27...Rf7 (27...Be8, was all that was left for him).

Maroczy needlessly extended the game with 28. Qg6 (28. Bg6 would have shortened matters), but a series of suicidal moves from Tinsley brought the game to a long-overdue conclusion.
