Piggybacking off of the ranpo and dazai rock paper scissors question

So I know I asked about what would happen is Ranpo and Dazai played rock paper scissors some time ago… but I was rewatching the prison arc and NOW I randomly thought of the question of what if Fyodor and Dazai played rock paper scissors together considering they have basically the same IQ and as Fyodor said “Two of a kind”, so what would happen??
