I would check\call the river here. I hate not getting to showdown on boards like this. When he raises you on the river, you're most likely beat.

However, some of the time, even at .5-1, opponents get pissed off at you for re-donking them and will raise again (especially as a bluff on this scary board). I would suspect you're losing here, and I definitely don't want to put 2bb in on the river.

I'd check\call and be a bit pissed if he checked behind (though you miss a little bit of value you make up for it by seeing a showdown and finding out what he limped in with and what he raised you on the turn with).

Please never fold the turn here at .5-1. You will often have a shitload of outs(you're only completely dead to T9, unfortunately you will see this here sometimes) and are still ahead in the hand quite often.
