A Good Exposure. We often call a particular exposure a 'good one' because it doesn't reveal exactly what hand you are doing.
This is one that came up last week.
It is always better if you don't have to expose any tiles and can just call for Mah Jongg and put all of your tiles up at once. But realistically.....we can't expect that to happen very often.
So, if you do expose, some exposures are better than others.
Lets look at the pung of 3 BAMS and kong of 5 CRAKS
What hands could they be a part of?
222 333 4444 5555
333 444 5555 6666
111 333 3333 5555
11 333 5555 777 99
That's quite a few hands to choose from. You might be able to tell further by what your opponent throws....or doesn't throw...or by what tiles are already on the table.
How about a 'not so good' exposure....not really bad, but does indicate exactly which hand you are doing. A Pung of any dragons is always this hand: 11 DD 111 DDD 1111Of course your opponents don't know WHICH number you are doing, but would be very hesitant to throw a green or white dragon. They will figure out the number if you call for either the pung or kong of numbers.
Lets say you call for a kong of 6 BAMS as in the photo below, now your opponents know exactly what you need: 6 CRAKS, a pair of WHITE DRAGONS, and a pair of 6 DOTS. This is also a hand where you can be sure if a player is dead. If 3 6 DOTS or 3 White DRAGONS are out on the table, this player is dead. You can call them dead and they will stop picking. More picks for the rest of the players.
