American Mah Jongg (2019 NMJL card). Defend against these exposures, showing atop another player's rack.
1. There are two hands she could be making, but there's just one hand to defend against. Odds #7 is a concealed hand, so you have to defend against 2019 #1; F 2B 1B 9B and soap are her hot tiles.
2. Those are 9Bs, not 6Bs. And there are five of them, so she's in Quints, and it's crystal clear that she needs 9C and you should not discard it unless you're ready to risk paying double because your hand is this close to mahj, run-on sentence notwithstanding!
3. There are very few dragon pungs on the 2019 card. And only one that goes with sixes (369 #3). But she has made a mistake; the sixes must match the dragon's suit. Call her dead. Her second exposure must be returned to the rack. The joker in her first exposure is still redeemable (FAQ 19-P).
4. As with problem #1, there are two hands she could be making, but just one to defend against. Don't bother defending against Consec #7 (concealed). She's making Odds #4. But which way? Her hot tiles: 5B 7B 5D 7D G soap. The fives and sevens are all key tiles. If you can see three 5Bs, let's say, then you know she has to get dots instead. If you see that her bams and dots options are both dead on the table, then you can call her dead.
5. Sixes in two suits. There's a likely hand in 369 (#5). But what about Consec #6? Her hot tiles: 5D 5B F 3D 3B 9D 9B. Keep an eye out for key tiles (threes and fives and nines) that might be dead on the table.
6. She's making Any Like Numbers, right? Maybe. Maybe Consec #4. Is that everything? No. Also could be W-D #5. Her hot tiles: F E W 4B 5B 6B. Those bams are key tiles; if you see three 4Bs dead on the table, you can eliminate Consec #4 from your worries. If E or W is dead on the table, you can eliminate W-D #4 from your worries. Any Like #1 and W-D #5 both need a flower pair; a key tile, yes, but it's unlikely you'll see seven flowers dead on the table.
7. Look for a flower kong on the card (FFFF) - one that can coexist with a pung of sixes. Could be Consec #6, but don't stop looking there. The League pulled a fast one on us, by burying a flower kong in the middle of a hand instead of always putting them on the left side; could be 369 #5. Her hot tiles: sixes in bams and dots, and fives, threes, and nines in all suits. The threes and nines and fives are all key tiles. Keep your eyes peeled!

Hi Tom,
I am wondering about #6 on November 11th column. If she is making consecutive 4, wouldn't the hot tiles be 3B, 4B and 5B?
Thank you,

Quite right, Kathryn! I missed the 3B. Good going!
May the tiles be with you.

>In Column #731, Problem 7, I believe you've listed a few too many hot tiles. Among others, you include "threes, and nines in all suits" as hot tiles. I think that should be limited to 3B, 3D and 9C; other 3's and 9's would not play with the exposed tiles.

Hi, John!
The hand 369 #5 is a two-suit hand. If the player is showing a pung of sixes, then she needs either threes or nines to go with that. We cannot know from the exposure which way she is going. She also needs a pung of either 6D or 6B, and since we don't know if her six craks are to be matched with threes or nines, ALL threes and nines are potentially hot. We can't assume that the position of the sixes (either to the left or right of the flower kong) is in "card order." It's bad strategy to intentionally position one's exposures in card order, and there is no rule saying a player must place exposures in card order. So one should not make assumptions about card order based on exposure order. Thanks for writing, and I'm glad you enjoy the columns!
May the tiles be with you.
