'''Sakigiri''' is the act of discarding tiles before they become dangerous. Usually, when sakigiri is mentioned, it comes at the cost of [[tile efficiency]] (hand speed). | '''Sakigiri''' is the act of discarding tiles before they become dangerous.

In general, tiles are safer when discarded earlier. After all, if an opponent isn't in [[tenpai]], you can't deal in. Sakigiri is discarding potentially-dangerous tiles early, even if those tiles would be useful to your hand. This technique is best used when you don't care about winning (e.g. you have a cheap hand, or you have a large lead). You could also use the tile as part of a [[mentsu|tile group]], or [[betaori|fold]] by never dealing said tiles. | In general, tiles are safer when discarded earlier.
