Home game so we all have a ton of insight into each other's play. UTG player is solid player but respects my raises. Villain (on the button) is tight, plays solid hands and can be pushed off hands.

Skipping the preflop action to get to the point:

Pot: $15-ish
Board: 963
UTG ($175): Leads out for $11.
Hero (next to act, $150): Raises to $31 with A2
Villain ($200): Calls $31.
UTG: Folds.

I raised as a semi-bluff expecting it to get either a fold from UTG or a call and a free river card. Based on my history and the manner in which villain called, I was 99 percent convinced that he had a worse flush draw than I did.

No need to dwell on what the play is if a diamond hits the turn. We're getting it in either then or by the river. But what if the turn is a blank? Jam the turn anyway to take the pot? Bet $40 on the turn to allow him to see a river and then basically plan to jam all rivers? Bet $40 on the turn jam everything except a non-diamond K or Q (smacks his range for top pair) on the river?

This situation -- where I had the nut flush draw and I was heads up heading to the turn with someone I was certain had a worse flush draw -- just hasn't come up that much. Curious what people think. Thanks.

What does jamming the river accomplish when no diamond comes? He folds his missed draw?

Calling on the button pre, he could have almost any 2 diamonds 87 or higher. So a lot of cards could pair him. Given your read of his flush draw, however, bet more than $40 on a blank turn. $88 in pot, so 2/3 pot would be about $60.

On a blank river, consider C/C to bluff catch if he's capable of shoving when he misses. If he's truly tight, he won't bluff and OK to jam if you think he hit a weak pair and will let it go.

Jam rivers to drive out any low or middle-ish pair he might hit on the turn or river. He is tight. With my raise on the flop, I can probably drive him off of top pair on the river depending on what it is and his kicker. But checking and bluff catching is an option, though he's not the bluffy type.

Two reasons I suggested $40 on the flop: One, it gives him odds to chase a draw I want him to hit. Two, it gives me a stack that I can shove on the river to get folds from those turned or rivered pairs I mentioned.

Like in LIMONs post without preflop action its like getting arrested calling your dad and telling him your in jail and then asking how do I avoid getting Butt $#%@ed tonight

how did you get there?also what do you mean he respects your raises maybe he is just tight,,, also I dont see why you would have to jam turn if the diamond misses a half pot bet is fine and can accomplish the same,and if this is your normal play when on a flush draw to jam turn on any blank, you should balance it and jam turns when you hit your flush, but i get the feeling your default play is to bet small when you make your hand....also think about what hand you can possibly represent when shoving turn, what hands would you play this way 99.66.33? would you go crazy and shove a set on the turn,,and why do you think he has a nutted flush draw? he can have 78,, you have blockers to the flush so its less likely he has a flush draw and if he does have the flush draw you now only have 6 outs but your playing the had like you have AA he can have a flush draw with a pair and decide to call a turn shove and if you classify him as a solid player its not likely hes calling flop and folding turn especially if he puts you on the flush draw.....did he tell you after the hand he was on a draw? honestly given your position and the fact you think hes on a flush draw your best play is to check turn hoping he will check back as well especially if he is on a draw,,,but if you want to maximize fold equity bet around half pot on turn and shove any river

you're not deep enough to run this bluff.

if you bet 40 OTT, the pot will be close to 170 and you'll be ~74 behind. for that price a shove OTR really will only fold out nitty players and missed draws

honestly, you have 114 OTT, pot is ~90, i might just shove brick turns because
a) you can get him to fold some made hands that are ahead of you.
b) he might actually call with a flush draw to try to suck out on you thinking you don't have a flush draw.

OP, I like how you left out preflop for "efficiency"

You knew you'd get moaned at for flatting 5bb open from utg while sat utg+1 holding A2s

Fair play but - fold preflop!

As played shove turn is probably fine given the low SPR.
