A fair attempt at the Colle System, but missing the crucial 2nd knight where my queen now occupies

Yeah, a mistake, too early to attack

Did not see that coming. Pawns in complete disarray now.

Ok, all is not lost, I have a plan, loosely based on the diagonal attack but it’s gonna cost a LOT of material...

Pretty much just letting him gobble my entire defence up at will.

Ah ha! It was all worth it...

First goal achieved. Now to continue that diagonal attack...

All going to plan, he seems hell-bent on marching both pawns up, oblivious to the long distant assault coming...

Was afraid of this, those 2 knights are going to cause trouble, but I must protect that diagonal!

Woa horse! I thought he would have kept pressing the 2 knight attack and given my last remaining pieces the run-around, maybe even forked me. But he chose to retreat. My original plan is still green. I think that was one of his biggest mistakes.
