The following hand made me question how to decide upon the correct bet sizes in a no limit SnG.

I was in the 2nd level of an online SnG, it began 9 handed and there were 7 players left. The blinds were 30/60, starting chips were 2000 and i had around 1800 after missing a few flops.

everyone folds except 1 limper from mid position, i am in the BB with and raise 4BB's to 300 thinking i am either ahead or 50/50 with the MP limper who calls.

the flop is

i think i am ahead although am not sure what to make of the fact that the flop is suited as well as having straight possibilities.

i bet the pot (around 600) and my oponent calls.

turn is at this point i become unsure what to do i think i am ahead but have only around 1100 in my stack and cannot bet the pot which is 1800. also i do not like the fact that i am out of position, and i expected him to fold to my pot sized bet on the flop if he was behind.

in this situation should i push all in, check/fold, or check/call. i opted to check call, oponent checked river was , we checked around again and i won the pot.

any oppinions on this situation would be appreciated.

Position is a devil here and the clubs are scary.

In all honesty I'd check as well and if he bets decide whether I believe him or not.

If I could get the turn cheaply I'd be happy when the club didn't hit.

Without any other information after his call on the flop I'd be very wary of AK or a pocket pair with a club.

Another strategy might be to push, but he's probably going to think he's got odds to call and find it difficult to walk away from (which may or may not be a bad thing).

Not to be nitty but 4xbb=240. You raised to 5bb
Preflop is fine.
Flop 600 is quite an overbet in the SnG world. You're stack is healthy and if he flopped the nuts and check calls here he's almost guaranteed your stack. Taking the pot here is fine, its already 600 which is a ncie addition to your stack.
Assuming you bet say 350. Betting about the same or a little more on the turn. Checking is terrible when this card hits, its basically a blank so without a read checking is bad here.
River: Value bet it, you'll win more often than not when you are called. Fold to a raise.

To Irexes: Checking these kinds of hands is generally a mistake. You have to fire out a bet. Remember even if you win the 600 only, its a nice pot this early.

Very wary of AK from a mid-position limper? Are you kidding me? Almost anyone raises this hand here.
If you're talking about the flop, pushing is a terrible play. The only hands that call you have you beat except the naked

Sorry I wasn't clear what I would do where.

If pushing is an option it's after the river, though I wouldn't.

If it's low buyin and early on so I don't know how he play, he could have anything as the quality of play is likely v. poor so I would consider AK a possibility though a PP with clubs more likely.

I agree the 600 bet on the flop is high, a lower bet would enable a bet on the turn but given the position as presented I'd check as a decent bet on the turn is pretty much going to mean all in.

I suck at explaining myself.

I wouldn't check the flop, I might check the turn after he called the 600 bet.

I think you got to stay agressive here. I would have bet around 300 on the flop, then about 500 or 600 on the turn. I wouldn't really know what to make of it if he raised all in, i would probably call off my chips here , not too many things that beat you. If he flopped a flush, your probably going to lose your stack unless your really passive and you check call his bets all the way through, but other then that he would probably raise with AK and if he called 4x big blinds, depending on if hes a solid player or not, you probably have him beat. IF hes a call machine, then i dont know, he could have anything.

I like the flop bet, the PF bet may have been a little big, but no bad.

I probably would have pushed on the turn, I am usually not afraid of 3 suits on the flop, but I don't want to see a fourth.

Push on turn seems to only get called by the flush or maybe a set

Who says I want a call?

I don't like that mentality Bonch. The pot is already large, I want to win it now, going all-in would not be an overbet. When I did the best at Sit N Gos it was when I played them in the most simple manner. No need to get fancy and no need to price in a call that may cost you the pot.

Everybody has their own style, but I won my games by taking down decent pots with good sized bets.
