Birds Opening Polar Bear

Chris Hansen won a Polar Bear System in Birds Opening 1.f4. Henrik Danielsen has added to its theory and practice for many years. This Flank Opening gives White an easy, repeatable strategy. White wins this game bullet chess game due to his better tactics in a position that he understands.

One key to the Polar Bear System is the setup with 7.c3 and 8.Na3. The pawn on 7.c3 serves several functions. It keeps a Black knight out of b4 or d4. It provides the option of a White pawn advance to either of those squares. It gives a White knight the square c2. It guards b2 against the Bg7. The opening is equal, but White usually knows it better.

Hansen was an Expert level player who has returned to chess after a long layoff. Chris likes that the Polar Bear System does not require as much memorization as more popular lines. Here Chris Hansen is "Polar Bear". He seems to be having fun.
