Opponent opened one nt. Her partner responded 2 spades, adding an alert saying Jacoby t.b. The opener bid 3 hearts and it was played in hearts. I can't find any reference to the t.b. Can anyone tell me? It occurred in the relaxed game and really doesn't make any difference, except I thought I would be able to find something about it and can't. I double checked on the t.b., so I know that's what was written.

Looking at the hand record it appears that it was a 1NT overcall rather than an opening for what it is worth. Most likely Responder was just trying to communicate that their 2♠ call was a Jacoby transfer - perhaps the b stands for bid. Of course that is wrong, since only the red suit transfers are Jacoby but it is common for players to use the same nomenclature for 2♠ = weak with a minor. I suspect it was pure accident that they also had 4 hearts. It is difficult to say what Overcaller might have thought the 2♠ advance meant but I doubt they were on the same page here.

If you don't understand an explanation, you should request a further clarification.

It doesn't seem like this a general bridge problem. Abbreviated explanations like that are only likely in online bridge.
