The Fishing Pole is a well known (If i say so myself) trap used my quite a few people playing black. The reason why this trap is so effective is because
1. It ruins white's castling position for a quick win.
2. Even if the trap doesn't work it results in a fine game for Black.
But then there is also the Icelandic gambit, which is good for black because:
1. Black gets to develop his minor pieces in good squares.
2. It gives black another fine game even if it doesn't work.
Therefore I want you to do 2 things below in the comments:
1.Vote which is better, and 2. How would You counter this if you were white?
These 2 openings and traps are one of the best in my opinion because it is very useful if everything goes to plan. Nothing can stop the power of these 2 openings and traps!
