This is a mandatory deal-in to dealer haneman, ura 2. The key point is noticing how abnormally low the suji count is at turn 17; only 5 passed suji makes this a medium risk scenario, with a slightly below 15% deal-in rate for single musuji.
Although the late turn number significantly diminishes the value of your hand, the dealer is also defenceless against your ryanmen mangan. Based on this simplified push-fold criteria from Miinin’s Sanma SMS (https://note.com/starmine_mj/n/n75d9700a3e20), pushing here is good EV (3-4 han minimum for open ryanmen).
