By employing betaori, a player has abandoned all hope of developing a completed hand; and instead, the player opts to minimally lose points via opponent tsumo or [[ryuukyoku]]. Of course, a player in betaori hopes to not lose points at all. | ||
==Determining safe tiles== | |||
The central idea behind betaori involves avoiding dealing into player hands. This requires deduction from visible tiles. The visible tiles are all tiles revealed from the player perspective. This include all discards, the dora indicator, and the tiles in the player's own hand. Of course, tile defense also requires the player's active decision to defend as opposed to continuing to push the hand towards tenpai. Tenpai is still very much possible in this process. | |||

'''Genbutsu''' {{kana|現物}} is a term for "safe tile" due to [[furiten]]. To identify safe tile, players rely on the furiten rule. Furiten refers to a player's inability to declare ron, if any winning tile is within the player's own discard pile. Therefore, discarding tiles applied by the furiten rule are the safest tiles to discard, against particular players. | '''Genbutsu''' {{kana|現物}} is a term for "safe tile" due to [[furiten]], by reading the [[discard pile]].

The most obvious tiles to discard safely are the one in particular opponent's discard piles. However, often, a player may possess a set of tiles in the hand, that are not clearly safe. In this case, a player may have to rely on [[suji]] and/or [[kabe]] to make an educated guess on a safe discard. | The most obvious tiles to discard safely are the one in particular opponent's discard piles.

The safest tile to discard is the identical tile discarded by the previous player. This is known as '''awaseuchi''' {{kana|合わせ打ち}}. Naturally, it is safe against the previous discarder. Temporary furiten renders it safe against [[shimocha|the player to the right]] and [[toimen|the player across]]. | |||
