1. Competitive bidding > 85%
2. Regular bidding especially insane jumps to 6 or 7 less than 10%
3. Not having structure in defense for attitude signals
Other than above GUBBO is quite excellent unless out of resources
In this particular hand I almost doubled. Had a feeling GUBBO would pull so took the plus. Note the excellent first round finesse by GUBBO in diamonds.
Very nervous when bidding 2H but remembered in identical situation GUBBO pulls when has stiff.
