Bet like 7 or more on turn.

4.75 will make you almost no money when you get called by anything with a spade, and it's also letting him know you're weak.

I'd also always bet flop when he checks to me. I hate flatting this kind of hand pre if I don't intend to get aggro when given the opportunity.

Thanks yeah the flop check was bad with no showdown value or equity

My turn bet sizing was with the intent of getting called by a spade + so far (just started playing HU) I've been better closer to half pot for value. I probably just am bad tbh. I didn't feel weak on the turn (felt like I had the best hand) but I guess if I had say, turned a set of 7's I probably would be betting bigger for value from drawing hands/set up for a larger bet on the river. So probably bet sizing leaks yeah :/.

Thank you for the advice Edzwoo .

It's important to note that by default you should probably assume when villain checks twice to you, your turned 7 is almost certainly good. If that's the case, you need to bet big to protect your hand and get value. If he has T8o with one spade and he calls turn, he is actually not making a mistake calling turn in this instance since he has the equity to continue (almost 40% if that surprises you).

If he folds T8o with spade, he is folding out his 40% share of the pot on that turn. I'm sure you can guess how important that is for your winrate in the long run, especially since this is a common situation.
