Hero has no reads on the table. It is 8/9 handed. This is hero's second hand. This will also be the first of three hands against Villain where hero has been involved HU postflop.

Villain is hyperaggressive middle-aged Indian guy. His vpip is close to a 100% over two orbits and has been attacking boards of various types multiway or heads-up. The table is commenting on his aggressive nature and his big bet sizing.

Hero has one hand with villain. Long story short, I 3! with AQo and get two caller. Flop comes eight high. I check, short stack checks, and then villain bets $75. I fold, short stack calls for less. Runout is a K and another low card. Villain rolls over Q8o and takes down that pot, which gives some (limited) insight on how wide he is playing. This is the first time I've seen him get to showdown.

Hero has around $310 and is the effective stack. YAG, but has only played the previous hand in question with villain and table. Villain is in the blinds. Hero makes it $15 in UTG+1, folds to villain who calls.

Villain checks dark.

Flop comes K52r. Hero bets $25, Villain calls. He checks dark again for a second time.

Turn comes 6d. Hero bets $30, villain calls. He checks dark again for a third time.

River is a 3x. Hero ???

I feel like putting a third bet here is super thin, and I have good SDV with second pair. There's no need to turn my hand into bluff, so I think checking behind is a good option. I also open the risk of getting raised and blown off my hand.

Given your limited information on villain checking behind is fine. Your description and this hand makes it seem villain is likely sticky and likely has a worse hand but you don't know that yet. Villain is obviously bad but so far off any normal strategy that you can't really predict what he is playing this way.

In general a bet isn't likely to get worse to call or better to fold. Plus random low garbage that has straight potential is a hand likely to play this way and most of those hands beat you on river with two pair or straights.

id bet the flop smaller.

against any decent LAG your turn bet is really bad as he will interpret it as weak and raise the turn wide to blow you off your hand.

as played yeah check riv.

ps i think you might have to change your read because theres no way a good LAG would let you get away with your line.

Don’t post results in the OP.

Checkback and win is fine. Even if you suspect you’re ahead on the river, betting opens you to being re-bluffed, as has been mentioned. Also, if he’s check/folding river, the river bet has no value anyway, because it’s never called by worse.

Even with a spoiler? Good to know. Thanks for the feedback and forum etiquette.

Everyone clicks the spoiler ����

On the flop, you have a middling hand with showdown value. I can get behind a check here, though I too would probably make the continuation bet.

Check the turn. You want to get to showdown as cheaply as possible. You already got your one street of value with your middling hand.

Not a fan of block betting turn vs this villain, we’re better off checking back and calling river.
