I'd mostly bet ⅓ pot on flop, but checking sometimes can't be too bad.
Turn is whatever, again mainly bet small but *shrug*.
River bet/3bet seems std. and it's hard to fold 2nd nuts when nuts is single combo. and single combo. 3rd nuts can play this way, there's not much else it should be but it's plo10 were some players might have random flushes here.
On the upside if you bet flop or turn (or both) you might get calls anyway and be more tilted.
