€500ish effective. Reads are irrelevant. Game is tightish but always around 3-4 players to the flop

Villain utg+1 opens to $20 and Hero calls in SB with 35 goes 5 ways to the flop

Flop: (€107) Q 7 2 all Hero bets 70. Villain calls, rest folds. Reasoning: I obv want to protect my flush vs 4 other players.

Turn: (€270) 7 Hero?

Question 2: Suppose you bet the turn what size do you go for? Hero has around 400 behind...

Input is appreciated

If he has a diamond he probably sees his hand as one or two oc's w first or second nut flush draw so he will probably call a strong bet. The only hand he would be dead to is p2's. Bet around 200 and expect him to call the rest on the river is he hits his oc.

Pre is very questionable, especially with less than 100bb effective. I fold this no matter what, though. I don't care how many callers there are. And reads are always relevant.

Bet $150 - $175 on the turn, leaving an easy river shove.

What do you do if Villain raises you all-in on the turn after your bet of around 150?

LOL. You call. Isn't that why you play 35 suited from the SB? Also, this is where reads come in -- they are very relevant.

Bet 150-200. Never fold. Jam any river.

Pre is a clear fold. Now that we are here, we are never folding. IF he has QQ then GG sir. "Chips!"

I agree that pre is probably a mistake. Reads are also relevant - what I wanted to say is I had none as I played the table for the first time and was sitting for like an hour.
My only read on him was that he played more tight than not.

Apart from that which hands do you think V raises on the turn which you can beat? AQ with the A KQ with the K? Don’t you expect to run into a FH most of the time or at least a better Flush

Any difference if we are in the BB?

No.

It depends on the V. Some will shove here with AdXx, some will shove only with the nuts. Some will shove with a 7.

Honestly, you can't play 35 suited from SB, hit your flush on the flop, bet, bet turn and then fold.

You are welcome to check turn, but that wasn't your question. (I'd never be here, so can't comment on what to do on the turn.)

Good rule of thumb on this...

1) You can only play 53s if you don't need to ask for advice what to do with it.

Agree. No it does not. Play long enough and you will see how important position is when playing suited connectors. By and large, you will not be able to play these hands very profitably upfront whether you hit or not.

Preflop
53s is really not a good enough hand to justify calling with unless Villain has a huge vulnerability postflop that you can take advantage of. And unless you're super deep stacked, the vulnerability needs to be some form of folding too often, as opposed to paying you off well, because with normal stacks, you don't hit enough to justify calling for implied odds reasons. If flops are usually multiway, that indicates that the game is loose, which means you probably don't have enough fold equity postflop.

Flop
I agree with the flop bet and like the big-ish size, although I'd go a little bit bigger, because I think Qx and flush draws are calling more. I think the big reason to bet is for value, moreso than to protect against better flushes.

Turn
I think the turn is a bet for value, same as the flop, looking to get value from Qx and flush draws, and also trips I guess. I'd go with a bigger size because all of that stuff will call bigger bets, and there aren't really weaker stuff that you're targeting.

Ouch..... seems like solid advice though. Lol.

As for the hand, seems pretty standard to bet $175-ish to jam river, and we're never folding turn if raised. There are a decent amount of bad rivers for your hand, so if you had some reads that V was really sticky with OPs then I could even get behind just jamming turn.
