The most common trouble action by weaker players is the off-shape point-based takeout double. Recently on the auction of 1
♦-Pass-1
♥-?, a player doubled on:
Winning the contract, and assuming a takeout double, I misplayed the hand and called the TD to sort out the meaning of the double. This TD handled it correctly (imo). First, since this was clearly a weaker player there was no point in imposing damages, which might just deter them from playing again. Instead the TD warned them to alert the double if they will be making this on points, and not on shape. This is a good thing: now the player knows that the double as played by most is usually based on shape, and not just points, and may decide to use this information.
In this redouble case, Id hoped the TD would address the situation in the same way. First find out what the redouble is (the TD was quite reluctant to do this, and it took several promptings from me for the TD to even ask the opponents what the meaning was). Once the TD determined the meaning, the TD would note that most play the redouble as showing points, and suggest they alert the redouble if they continue to play it as merely showing a fit. There would be no damages assigned.
As noted above, if I wanted to protect myself I needed to ask before assuming the redouble was based on values (and sorry if I click on your doubles and redoubles in obvious situations!). This is reasonable and fair given the mixture of skill levels we see in tourneys.
TDs need to know how bridge is played, and, using this knowledge, help educate the players as appropriate. I opened this thread since, imo, this TD did not handle this well.
