Not re-raising preflop is inexcusable. Even for a tight player, you need to push your hand strong here. The whole hand plays differently when you do re-raise preflop.

On the turn check-raise, he could have JJ+, or AJ, or any JsXs that picked up outs. We don't know because we don't have information.

As played, the call is fine because the pot math necessitated it.

From the tone of your post I bet he picked up and hit the spades... which sucks.

Re-raise preflop, bet or raise a lead bet on the flop. If he comes over the top, push.

Much simpler, easy decisions that way.
