paramount: <The notes to this game are funny as well as informative, on 32...Bxg2+! Nimzowitsch writes "Now the Bishop runs amok! The death of the Knight makes him utterly reckless.">
Yes, the game listed in My System.
BUT, there is much better line.
The only sensical response is 33.hxg3 Qc6 34.Rd2 dxe3 35.Re2 Rxg3 and black win
Other response to 32..Rxg3!! beside 33.hxg3 would bring the mate closer.
A. 33.Bxd7 Rxg2....mate soon withe the threat Rg1+ (double checkmate with b7 bishop)
B.33.Bxg8 Qc6.... and triple threat to g2 pawn means checkmate in a blink of an eye.
I posted this comments before in another Nimzowitsch game...I if you want to study My System, please be cheapen yourself with using the assists (your teacher, engine, corrective books or annotations or notes, etc,etc,etc). Almost all the games in book contain the very basic mistake like this.
So dont take boldly the games he was feeding on you, you'll be always trapped in the wrong line.
