Failure to play e6

 There were a number of errors in this game, but the first one is the failure of Black on the right board to play e6:

Black plays Bxf3, which further weakens f3:
Black tries to shore up f7 by playing @f6, not a bad idea:
Black on the right board plays Nd6, hanging the d-pawn and allowing an attack of f7.  Maybe Ng5 is better with the idea of going Nd6:
This is getting serious.  White takes on f7.  Black does not control e6:
White plays B@b3.  When Black interposes, he takes on e5.  This is a mistake because it gives back control of e6.  If White can get a pawn, he should play @e6 instead.  If he does not get a pawn, he can play N@f4:
White plays N@f4 now, which is good.  Black plays N@f3+ which is awful:
Black plays @g2, another meaningless one move threat.  After Rg1, she plays e6.  So the queen is hanging.  If Nxd5 and exd5 the e6 square is opened again, this is all a result of not defending the square earlier:
White plays @e6+ as planned:
White plays e4.  This is a good move, better than waiting for material.  He needs to take control of f5 and or d5:
White now has control of the light squares, but he might not have much material to work with.  Because I cannot take the queen, Black should go back to e7 rather than taking the pawn.  Going up is hardly ever good:

Here White plays Nc3+.  He should have asked for a bishop to play B@c4+, preventing Black from retreating to e6.

My partner is playing Qe2+.  I am happy that he is not waiting for material which might be slow in coming.  Note his rook on g2 attacks g7:
He plays Rxg7+.  He then plays B@h3+ which is a waste because it can be interposed.  B@e6+ is better:
Black goes to c6.  This is a mistake.  She would be safe on c6:
Here White allows the trade of his knight on c3 for the knight on e7.  Even though the Black king is drawn into the center, I am a little bit doubtful.  Usually trading while attacking isn't good:
Admirably, my partner continues his attack without the need for additional pieces:
White is closing in on a mate:

And there it is!  All because she didn't play e6:
