This post isn't about psyching, so I apologize in advance for any thread-jacking.
Justin is 100% right, imo, about going out of one's way, as an expert or advanced player, to avoid pissing off beginners. However, and without adopting han's somewhat radical view, the truth appears to be that most club players are pissed off simply by an expert turning up to play...if he or she is playing with another expert.
In our club, we had a team game on Thursdays...it was handicapped (the score, that is, not all of the players). My wife, who is advanced rather than expert, played with one of Canada's top women players and I played with her husband, who is no slouch.. a multiple national champion. We'd win maybe half the time, due to the handicap... but attendance plummeted. Thursday shut down and a Monday night 'team of 8' was formed: an A player is 3 points, a B is 2 and a C is one, and the team cannot total more than 8. That effectively killed any hope of any of the best players playing on teams with friends. So the best players, who had gone out of their way to play at the club to show support for the owners, don't play team games at the club...and attendance has skyrocketed.
I recently played golf with a pickup foursome, one of whom, it turns out, plays in the team of 8 event. I had not met him before, and he didn't recognize my name... I mentioned that I played bridge and he described the team game and stated that 'there used to be a game on Thursdays, but there was a team of good players who always won, and everybody else felt that it was unfair for them to play together, so the game died'
The moral of the story is that most club players do not want to play bridge as we know it... and they resent the mere presence of those who do...psyching will piss them off fast but so will cue-bidding to a slam... or taking more than 20 seconds to think about a play...or simply winning consistently...depriving them of the chance to outshine their peers by winning a club game.
Sorry for the rant, and I still won't psyche against most club players... but the rare one who thinks like jb...yes, I will and should (on the right hand) psyche against her
