T67 Openings

Below, the top 10 Openings for T67

4 King pawn, 4 Queen pawn, and 2 others, Dutch and English.

Hardly much of a change over the seasons in major openings played, with the split between King- and Queen-pawn, much the same as before, even the percentage is close, 51% for King's Pawn this season,compared to 53% : not  a significant change.

In fact, this is effectively the same as T66, with a switch of ranking between the Spanish Game/Ruy Lopez and the Indian/Torre Attack, and only by 1 game, plus the Réti loses out to the Dutch ( but since the Réti  is often played as a transpositional opening, its hard to tell what the intended opening was :)

Oddest opening, at least from my view, is 1.e3, occurring 4 times.

Appropriately, White won only 1 of these games ( and that was via a blatant Black blunder), losing 2 and drawing the other.

Only 6 games in the King's Gambit, with a slight edge to White, but no Falkbeer Counter-Gambit this time around.

Eleven games played with less than 10 moves, but no traps, just over-looked tactics.

Longest game : 124 moves and decided by an unfortunate mistake by the knight-less side to leave a King, Knight and Pawns vs King and Pawns ending, which was played well on both sides until, as would seem inevitable, the knight endured at the end.  

However,  could it have been saved by Black at the 111th move ? 

Black to play
Probably due to tiredness or time-trouble, Black played a2+,leading to a loss. 

What should Black play to give himself a good chance of a draw ?
