Botvinnik played here a very instructive game with a nice combination to crown it:
White to move
This is a very nice example of how in modern chess the game happens on the whole board rather than a restricted area. I like it very much, thx for posting!
From the point of view of the combination, I should probably have shown the position one move later, but I like so much the first move played by White to disorganize Black's position!
Yes. And in fact, the first move you chose is the one where the forced events happen, so from my point of view it is where the combination starts.
