200-400 Ace to Cinco TD

[HOWMANY]

I never see anyone slowplay/trap in 2-7. People also tend to play much more aggressively on small bet rounds so I'd expect him to 4bet everything that beats you and some that you beat here.

I wish I could say more but I'm really not familiar with how powerful your hand actually is here. It looks really good to me but I know it's a lot easier to make a good hand in A-5 than in 2-7 so perhaps your hand is much more marginal than I think.

I think I would just bet after you both pat and then check the river (or bet? this is another spot where I'm not sure how good your hand is and how good it needs to be to value bet). However it is possible that this idea is just being results oriented.
