I've been so busy with posts elsewhere about other things I had forgotten all about this.
Anyway the action is back to you and you have an open ended staright draw holding the
with a board of:
and it is just you and the button.
It costs you 10k to call and there is 35k in the pot.
I believe you have to try and put the button on a hand here and its' unlikely imo that he hasn't got at least top pair or a decent draw like the nut flush draw (Ax suited in hearts) or a straight and a flush draw with something like
or even a pair and a flush draw (K something in hearts) and the reason for this is that there were so many people in the pot.
Hence I would conclude that at this stage you have to do some basic maths and work out what your chance of hitting the straight is and whether or not you are likely to see the river if you don't make your hand on the turn.
The pot is offering you 35/10 or 7/2 and there are 45 cards unseen and 2 in each of your opponents and your hand along with 3 known flop cards so you need odds of 37/8 to make the call based on direct pot odds which you are not quite getting and assuming all your 8 cards are clean outs which they may not be if your opponent is on a flush draw or a bigger straight draw.
However the button also has a further 40k behind him so assuming you make your hand you can potentially get that off him too.
I personally favour the call here taking the pot to a total of 45k but I'm not sure this is that clear cut. Raising can be an option if you feel confident that you know your opponent or feel he is weak enough to make him have to lay down to a reraise but with 40k left its quite possible hes going to call anyway. Maybe the fold could be correct but imo my opponent is going to be holding something which means if I get my card I'm liekly to get all his chips.
Anyway nin real life as the cut off you call so we'll move to the turn.
