4.1 Taatsu
Two tiles that become a sequence with one more tile are called a taatsu.
34-pin becomes a 234-pin sequence with 2-pin, or 345-pin with 5-pin. Tiles that bring your hand closer to agari like this are called ukeire.
For two tiles one apart, like 79-pin, only the 8-pin in between is ukeire.
12-sou has only 3-sou as ukeire, since there is no number below 1. 89 likewise has only 7.
Two identical tiles are called a toitsu. One more copy makes a triplet, or it can serve as the pair as it is.
Try picking a tile from the taatsu that becomes a sequence with 2-sou or 5-sou.
