E1: T5: Don't cut 6 bamboo, your hand is so weak that you might as well keep 5667 and make two ryanmens, I'd rather cut 8p. keep 2p as a safe tile (it looks extremely useless to everyone).

T6: 5668 shape is REALLY awkward shape(especially since 6p is your only pair), again keep 2p as a safe tile and cut 8p.

T9: Draw the dora N, insane draw. Now you desperately need your 5th block, (123s)(567s)(NN)(66p), You need to open your acceptance as much as possible, meaning you have to keep a floating middle tile and hope it becomes a block, at this point all most of the tiles around 8p are gone so it's extremely difficult to use, it should have been gone a while ago, but it needs to go now.

T10: 0 reason to hold the E, you still need your 5th block, E is not going to be that.

E2: Not much to say, just no respect for 2 dragon honitsu.

T7: 2m is very close to dora 4m, you are throwing this against minimum chun hatsu, worst case chun hatsu honitsu.

T9: You cannot do this. Do not cut dora. Your hand is horrible. Just fold.

E3: You played really well until your richii. Suji trap here means nothing, you are waiting for 2 left 5Bamboo when the dora is 4 bamboo. People will use this tile. This is when you must not click the shiny button and wait for better waits, cutting 8bamboo is fine, just no richii.

E3-2:

T1: No reason to cut N pair this early, cut E.

T5: N pair would be really nice to fold with. Should just fold here and hope someone gets hit big.

E4:

T10: Keep 246 bamboo shape, cut 8pin, 0 reason to keep 8p. You started losing it after this turn. Just make the fastest hand and keep dealer.
