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...
16. Qg5e3 Qd4xa1 17. Bc1d2 Qa1xa2 18. Kg1g2
Pretty much just letting him gobble my entire defence up at will.
Ah ha! It was all worth it...
19. Bd3xh7 Nf6xh7 20. Qe3xb3
First goal achieved. Now to continue that diagonal attack...
20... Nb8d7 21. f4 Nh7f6 22. Kg2h1 Rf8b8
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.
