1€ Spin&Go post flop AKs on rainbow TT4 flop

Shove is last thing to do... You just get most weaker hands to fold and most better to call. Probably weaker Ax calling is more likely than better hand folding. Also you are in position so no need to check-call flop at least

Basically there are two reasonable options on flop. Check as you have clear showdown value and 6 outs to improve or cbet small for value and equity denial. Small on this case would mean like 40 or so. Both lines has good and bad sides.

If you check plan is to call most turn bets and evaluate river. Unless sizing is big which can make fold reasonable.

But in general when you do make bet or raise postflop you should think if it's for value or as bluff. If you cannot tell which it is then it might be best to think of more passive option. There are of course situations where its not clear and it can be more of equity denial or that your range has advantage over villain range but going into that make no sense really at this point.

But of you think about your decision on flop in this hand from that view it should show clear problem.

Thanks for the detailed answer.
I guess the fondamental issue I have right now post flop is not reevaluating the strength of my hand. That sounds stupid and basic.

Completely agree. I think I like checking even more at the BI I play at.

How would you evaluate opponent sizing? I'd probably call under 3/4 pot without too much thought, is there a rule of thumb?

I'm not sure I fully understand this part.

Thank you again.

Sizing depends on what turn card is. If it opens good amount of semibluff combos villain can have then you can call bigger bet in general. So 3/4 pot bet on TsTh4d4 is tougher to call than on 5d turn. Of course also earlier tendencies of opponent matters if there are some.

With last point I meant to think what your flop shove achieves in this hand. What stronger hands does it get to fold or weaker hands to call. This is sort of basic thinking process in all hands. Without it it's more or less clicking buttons without any real strategy behind.

Your effective stack size is really big, it doesn't make sense to shove. I think is better to do half pot size bet. If the villian re raise I will consider to fold. I don't see this check-raise as bluff.
