Hi everyone,
This is definately a tricky play and one that should not be attempted without a very good read on your opponent, however it can maximise the return you get out of some hands when you are sure of your opponents holding. It is something I have been trying to get better at the past few months as I used to use it hardly ever at all and I thought I would post two hands up here where I tried it (one with success, one with absolute failure

) and see what you guys opinions are on it.
First hand
----------
I have Q9 spades in the big blind, in a 1/2 GBP (Crypto, so we were playing in pounds) cash game. Button limps with about 100 pounds in his stack, SB completes who is short and I check the big blind covering them both.
Flop 8spade 6spade 2heart
SB checks and I decide to lead at this board. It is unlikely the button has any of this and since the SB checked I think a bet here has a good chance of taking it down right now without having to hit any of my cards so I pot bet it. The button flat calls (hmm I think.....probably a flush draw, but is it higher than mine?) and the sb folds, not the greatest result but we get to see the turn......
Turn Adiamonds.
Great, I missed and am now out of position with a draw, although I think he probably has a flush draw as well. I am of course worried incase he has the nut flush draw. However, I realise, if he DOES have the nutflush draw then that ace must have hit him, so I check to see what he does. He checks right behind me....I pretty much figure if he had Axspades here he would definately have bet that turn so I dont think he has the nut draw.
River 10 spades.
Bingo! I hit the flush! Now how much to bet I think (pot size prob). I however reason with myself he has a flush as well and I want to get the max. He does not have the nuts I am sure but if he only has a baby flush he is prob just going to flat call me if I bet. Since I have the Q spades in my hand and the 10 is on the board, KQs and K10s are out of the question for him, the only hand I can conceivably see beating me is KJs and there are way more flushes he can have that I am beating. He will obv bet if I check so I weigh it all up and decide to river checkraise him all in. I check, he bets as planned, and I CR all in. He pretty much insta calls with....K7spades...urgh
Second hand
..................
This is
ladbrokes 2/4 dollar NL shorthanded, all of us have over 400 infront 3 handed.
Button limps, I complete in the SB with 910o and BB checks.
Flop 9spade10spadeQclub
Great flop for me, although I could well be second best here (I am obv playing on this board tho). It is insanely draw heavy to the point that there is more likely a card going to come off that shuts me down and can freeze me than not, this and the fact that I am out of position for the whole hand lead me to check/call with the intention of potting a blank turn. I check, BB checks and button bets the min. I flat call it and BB folds.
Turn 9hearts
Bingo! I made my house! Now I Decide to slowplay and hope he makes something good (on the flop I hoped he had a queen and not some huge draw, now I hope he has a draw and gets there). I check (I prob could have bet a little here thinking about it but anyway, I checked) and he checks behind me (This shows me he has a draw and not a Q....if he had a Q he would bet the turn again)
River 2spades.
Mmmmm this is a good river. I am sure he was on a draw, it just depends if it was the straight draw or the flush draw. I think about betting but then realise this. If i bet he might only flat call me with a small flush - we are deep and he is not stupid, he knows his hand could well be second best and I doubt I would see a raise from him (unless he has the nut flush). He would also fold obv if he just had a jack and missed. I might, however, get a call out of a lone queen (but I think this is only a small chance, I am sure he would have bet the turn with a queen). However if I check....He will DEFINATELY bet any flush, and I can raise him... and he might well bluff the flush if he had missed the straight draw and I get extra equity that way as well. The downside of it is he will definately check a queen here (but as I said before I think this is the least likely of his holdings). After weighing it up I decide to check. He bets 24 and I CR to 100. He insta calls and mucks :drums :drums what i am sure was a flush.
Comments on both hands appreciated please
