In the same spirit as two moves ago, before White arranges a blockade by Bg2-f3.

Thanks to the double threat at f3 and g1, Black wins material.

Tal later converted his extra exchange into victory.

Finishing off Black's idea of ...Nd7-c5 with a blockade.

White is also better after 1...Nd7 2.cxb6 cxb6 3.Bb5!

2...Bxf3 3.Rxf3! , keeping the Be2-b5 resource.

Thus White recovers the pawn and also gets rid of his "bad" bishop.

Preparing Nd2-c4 with some advantage thanks to the superior pawn structure.

A strong pawn sacrifice, which creates a passed pawn on the f-file and enables a blockade on e5.
