Before I am ambushed with criticism, I admit that win or lose, hindsight informs me that I made some incorrect plays on this hand, and this check could well be one of them. Either way, I can at least tell you why I decided to check.
With two callers I stand the chance of losing my whole stack if I run into a set, yet perhaps only winning a small pot if I am way ahead. From my experience, most players on my chosen site check a set when the pot is so huge, believing that on the Flop or Turn, someone will make a bet and commit themselves with a dominated hand that they will find difficult to fold, such as Aces.
If they do indeed have a smaller overpair such as Tens or Jacks then I fully expect them to bet around 3/4 of the pot, especially considering the scary flush draw and the fact that I have shown weakness on the Flop with a potential A-K.
IMO, offering a free card isn't too much of a problem. For me, many hands can be played more effectively on the Turn as people realise that they have only one more card to see. I also find it easier to decipher between hands on the Turn as the betting alters dramatically from what it would be on the Flop.
The bottom line is that if I reach the turn for free, I will have a better understanding of where I am whilst simultaenously keeping the pot small as possible if they have indeed hit a set. Of course, they could hit a flush, but I doubt they would have folded that on the flop anyhow with so much already in the middle.
Having said that however, if I check raise and am re-raised again, I still won't know if they have a flush draw, open ended straight draw, overpair or set, so I agree with those that suggest this is perhaps one hand that I can't get away from whatever I do. If I stick any money in, I honestly don't think I can fold to further action due to the amount of possible hands they could hold.
Perhaps this is why I checked, an attempt to keep the pot small.
Anyhow, that may all be bollox to you, but either way, what would your next action be after that bet?
ps. Thank you to every for your input. I feel I leanr a lot from hearing everyone's views. That's why I'm such a big fan of the hand analysis board.
cheers
