Betting Flop

For me a very clear fold pre (even without absurd rake).

Flop I'd rather check but nothing wrong with betting half. Why do you think these "scare cards" are to your opponent's favor? You can't (well at least shouldn't) try to protect every mediocre made hand you flop.

I'd probably open it too against most opponents.

I think betting and checking are viable options. I'd say my default would be to check.

What winrate would you guess opening this hand generates in a 1/2 game?

Some 23xx hands can be opened and if we are going to open them it may as well be for a Steal. What would this hand have needed to be playable in your mind? No aces allowed.

I think if all the cards were 6 or below it would be worth playing. If the 7 was T-K the hand would probably would be worth playing. Of course double suited makes a difference rather than three to a suit.

I think what throws this hand off is the disconnected side cards: Of the six total combos the only really playable hands are Kxs and 23.

Its a little of everything. Making the 7 a wheel card or a broadway card is better, having two spades instead of 3 is better (and double suited better still obv).

Flop I'll disagree and say that bet seems really really bad to me. Getting raised would be a complete disaster. There are very few bad turns for this hand.

Around half of the 23-hands with no A open (I always assume pot open, don't know what exactly you mean by "a Steal").

A triple suit with disconnected cards is not very close to being in the top half. If we take the rake into account these 23xx and similar are exactly the type of hands I'd start tightening from. In the game in question I might open 10-25% of 23xx, also depending how much they defend and the more they defend, the more I tighten mediocre hands!

My intention is to simply fold to a raise. I don't think people raise-bluff nowhere near enough for it to be a problem. In theory you might be right - betting is wasting a good bluff catcher (once flop is checked). I don't think people bluff enough even after the flop is checked, which devalues the check-line a bit.

Thank you everybody for the replies. This drove home that I need to improve my preflop play.

Rake is disproportionally high at those stakes and players play too many hands preflop. This combo leads to a preflop strategy that is really tight accross all positions.
