Action bet! (8/b)

OK

I called 5th

6th

I check and he once again bets after he catches a total brick.

Now what should I do?

BTW yes this was 20-40. The action bet is great for the game IMO. And it might be a requirement of 200 now that I think about it. When split pot games are dealt you typically leave the bets in front of each player when the pot is HU so the pot in the middle always seems smaller.
