*A {{#mjt:2233m}} shape can be treated as two separate {{#mjt:23m}} ryanmen. However, they both accept the same tiles ({{#mjt:14m}}), so doing this isn't as efficient. The shape can be decent, since it has a ryanmen wait once you reach [[tenpai]], | *A {{#mjt:2233m}} shape can be treated as two separate {{#mjt:23m}} ryanmen.

The shape can be decent, since it has a ryanmen wait once you reach [[tenpai]], but fishing for the [[iipeikou]] will slow down the hand. This shape can also be considered as 2 pairs. | ||

When you are likely to [[pon]] one of the triplets (e.g. [[yakuhai]] pair), then keeping 3 pairs can be good, since you'll be at 2 pairs once you make the pon. | When you are likely to [[pon]] one of the triplets (e.g. [[yakuhai]] pair), then keeping 3 pairs can be good, since you'll be at 2 pairs once you make the pon. | ||
Also, when you have an open hand, keeping pairs is relatively stronger than normal. This is because you can pon with any player's discard, but [[chii]] can only be done to the player to the left. | Also, when you have an open hand, keeping pairs is relatively stronger than normal.

If you have 4 pairs you might want to consider [[chiitoitsu]], but if a sequence or triplet forms, you should probably discard a pair and go for a normal hand. At 5 pairs, you're at 1-shanten for chiitoitsu, so you should likely go for that. | If you have 4 pairs you might want to consider [[chiitoitsu]], but if a sequence or triplet forms, you should probably discard a pair and go for a normal hand.
