1.b4 Nf6
2.Bb2 g6
3.g4
Black counters the b4 played by white with fianchettoing the bishop on the kingside. The position creates an interesting setup with white challenging the black’ pinned knight with the move g4. This may not be that vital threat but it surely generates exchanges of the dangerous b2 bishop.
The sample game demonstrating the polish spike is as below:

Polish spike opening can be played against players who try fianchettoing their bishop on the king side and exchange such a bishop with which the activity of a black player might be reduced. Moreover black might be forced to not castle on the kingside in such an opening as the attack may loom fast on the black king if castled on the kingside. White’s king might just stay at the center and attack black along the flanks. This opening might prove handy if played in a no castling chess variant.
