What is more sinister in the tactic that I posted above however is that the victim is unaware of it happening, which if works makes the effect more dramatic. The real sinister effect is that by using a tactic like this might enduce the other golfer to lose self-esteem and over time really have a damaging effect.
Yes, I see that now.
A new high in gamesmanship.
And a new low in sportsmanship.
But, hey, if that technique is now 'in play', it's best we all know about it now. No doubt, a series of training classes in 'psychological trigger abuse' is now in order (especially for match play tournament players).
