I hate low straights. Dont think that I would have played much differnt. A bit surprised he acted to nitty (no re-raise on flop or river wtf?) Lucky you still have a chance to come back

I may check that river, but I'm not sure what I'm trying to accomplish. It's a scary board, so the decision completely depends on his action obviously.

Board pairing saved OP here somewhat.

I'm no HU expert so the river bet is probably fine. Normally I'd bet less to protect against raises from FHs where we have to fold. Thing is HU people call down with J high
