was this a good bluff....not for me
Personally for me the board is not suitable or scary enough for a bluff here.
But there are several areas of suggested improvement, let me explain my thoughts.
Firstly and most importantly for me.....I don't really have enough information about his hand to know if the bluff is going to work at the point when you chose to shove on the turn.
Mainly because you lacked the information that his actions on the turn would have given you.
So what is his range here?
If he is playing quite loose his range will include small pairs and suited connectors you could easily be shoving into a set or 45 here and be totally crushed!!
It is also possible that the limpers are playing these hands and waiting to check raise themselves.
We can't play thinking there is always a set out there but this is a 4 way hand and there is a much greater chance of it...
I actually think that leading out yourself here into three other players is too optimistic. If you have been playing tight your cbet should get some respect, you could try leading out here and you might take it down...however personally for me there is too much chance that one of three other players will have hit this flop. If it was heads up I'd be leading out all day.
So you check and the vill leads out on the flop into 4 players not something usually done with complete junk....so what are you putting him on now? " either a complete steal or i figured he can't have much more then a small over pair to the flop, hence the tank/flat call"
.... So good players aren't tank calling with sets to lure you in then?.....
OK Ignoring the fact that it may be a bad bluff because we may be shoving into a monster...we then come onto the check raise.
As was commented on, your check raise looks too small and gave him good odds to continue.
For a check raise bluff I prefer to call his raise and then raise the size of the pot.
So here he raises 75 and the pot is 175. I would call his 75 which makes the pot 250 and then raise 250 so I actually prefer to stick in 325 as the raise , this is nearly double what you bet (175). The pot would then be 500, it now costs him 250 to continue, this is only 2:1 and you take away all drawing odds. Only a decent made hand will continue and if he does you now know you are beat and need not put in another cent.
The big problem
here is that this pot is already bloated because it was a 3bet pot with 3 callers and is already substantial.
Almost any decent check raises pot commitment issue for you here, and if that is the case you may as well just shove all in on the flop! The problem with that of course is we may already be crushed, so that looks like spew.
So if we are not raising should we call or fold? Its debatable.
If we call on the flop here out of position with poor pot odds
to improve our hand we need to be planning on setting up a bluff on the river, but is this the board to do it on? Not for me, the cards don't fit with your perceived range as the preflop raiser..if bricks come the only thing you can rep is a flush here.
If we did call the flop I think it unlikely that with 77 he is going to bet the turn once you call on the flop, he has to be concerned he is behind your range as a tight preflop raiser.
If he then bets the turn I have to give it up...if the turn is checked and the river is a scare card then I pot it first on the river to put maximum pressure on him.
Folding is yuk and feels like rolling over too easily but with the low board here and being OPP we just lose our initial 25c and its probably correct.....i suppose it depends on how good and confidently you can bluff on the end.
hope this helps
