【天鳳】 四特南喰赤 四段【１４２】 オンライン対戦麻雀 online mahjong tenhou

東２局は一応先制ですが、カンチャンかつ下家のテンパイが濃厚なので立直は正直迷いました。しかし一発ツモが魅力的すぎてかけましたが、あえなく放銃してしまいました。
東３局はあがれてラッキーでした。ちなみに下家は５ｍ・５ｐ待ちのトイトイでした。上家は５・８ｓ待ちで、立直ピンフイーペー裏ドラ１という手でした。
東４局の１３巡目の１ｐ切りはかなり危なっかしいですよね。対面が三色かチャンタ濃厚なので、責めすぎない方がよかったと思います。しかし他も会うな荘なので、迷いますね。
南３局は配牌がよろしかったですね。５巡目がどうするか迷い、シャンテン数戻しになりますが、喰いタンできることを優先して１ｍを落としました。麻雀何切るシミュレーター version 0.9.0で計算したところ
①８ｍ切り→２０種６５枚②６ｍ切り→１９種６１枚③１ｍ切り→１０種３２枚となりました。和了確立も③は低いので、効率的にはミスですね。結果としてはあがれてほっとしました。ちなみに下家は２・５ｍ待ち、対面は５・８ｐ待ちでした。
よろしければアドバイスいただけますとうれしいです。
よろしくお願いいたします。
In the 2nd East game, I was the first to make a move, but I honestly did not know whether I should go for it or not, since I had Kan-Chang and the under house had a strong Tempai. However, I decided to play because I was tempted by Ippatsu Tsumo, but I let go of the gun without any luck.
I was lucky to win the 3rd East game. By the way, the lower house was waiting for 5m and 5p, and the upper house was waiting for 5s and 8s, and the lower house was waiting for 5m and 5p. The top player was waiting for 5s and 8s, and had a hand of tachinao pinfu eepe ura dora 1.
The 1p cut on the 13th round of East 4 is very risky, isn't it? Since the opponents had a strong three-color or chanter, it would have been better not to blame them too much. However, the other games are also very interesting, so I am not sure what to do.
In the 3rd South game, I was not sure what to do on the 5th round, so I decided to drop the 1m, because I wanted to be able to eat the opponent's hand. I calculated the following using the Mahjong What's Cutting Simulator version 0.9.0.
(1) 8m → 20 kinds of 65 cards (2) 6m → 19 kinds of 61 cards (3) 1m → 10 kinds of 32 cards. Since the probability of winning is also low with (3), it is a mistake in terms of efficiency. As a result, I was relieved to be able to win. By the way, the player below was waiting for 2.5m, and the player on the other side was waiting for 5.8p.
I would be happy if you could give me some advice.
Thank you in advance.
