OltBrink

This system was played by the young pair Brink - Oltmans in the Dutch top division. The other pairs were not amused by this ultimate agressive strong club system! The 2-bids are compulsory, and must therefore be made even on hands like xxxx xxx xxx xxx ! Not surprisingly, this system is only in use when not vulnerable.
