i have been at the table for about an hour and it is a fairly passive table except for V who has played about 80% of the pots and has raised everytime it has been folded to him. The game is 1/2NL and the table sees me as a TAG player who has taken down a few pots pre flop with 3bets and taken down pots on the flop with cbets. V is in the BB for this hand.

Its folded to me in middle position and i look down at A8 and raise it to $8 and its folded to V in BB and he calls.

Flop KQ5 and V checks to me and i bet $10 into pot of $21 and V calls. Turn is a 9 and V checks to me and I bet $16 into a pot of $41 and V calls. River is a 4 and V checks to me...

Do I fire here? I know his range is super wide in the BB but i figured he could have a weak K or a Q and he is the type of player that would check call all the way down. It also ran through my head that he had a smaller flush draw like J8ss or 109ss. I think his range leans more towards pairs like K with a weak kicker or a hand like Q10.

Opinions are greatly appreciated

Bet bigger on flop and turn.

You should either bet 1 street or all three here. Most of his range for calling flop is still calling turn so betting twice and checking river sucks. Even more so as your sizing is way too small.

Raising with A8 suited mid position is not tag.

Pre is fine if they are fit or fold post...I'd go $10 and keep that size consistent from MP. More otf bc we wanna win more when we hit and also win more when we dbl barrel and get turn folds.

As played, the turn is pretty much the nut worst card to barrel. Check it back. We have SD value w/ace high and checking it will induce bluffs otr vs a player like V. We can bluff catch. $16 into $41 gave me HIV, thx a lot OP, wtf?

Check back river. We hardly fold out better and never get called by worse.

Also, stack sizes would help gameplan this, imo.

Bet more on the flop. If he calls, as he did in this case, then check behind on the turn since most hands he check/calls the flop with will more likely check/call another street or even check/raise if villain is slow playing a big hand.

Check behind on the river both as played, and hope villain has a missed flush draw and your ace high is good.

your bets are weak sauce. you might as well check, I don't know what the hell your sizing accomplishes. don't post results btw.

are you betting the same amount otf and ott if you have AA or AK?

I actually like the bet OTF. I like to keep my cbets low because I play pretty loose in position and it will cost much less to cbet when you miss. (some players will call lighter if you bet small, so adjust accordingly.) Also, I believe you miscalculated because there should only be $17 in the pot OTF...

On the turn I think we need to bet much bigger, we have $39 in the pot at this point, betting $16 at this point will probably get you called by a ton of weak pairs. I'm not doubting he could have A5 right here. Bet the turn $30, you should be able to get enough of a read to see if a big river bet will work, but as played I probably check the river. I think your hand looks extremely weak and if you show up with a big bet now he may very likely call light. I think he's really only folding out missed flush draws.

pre-flop i'd probably fold this hand in mp or limp if i have a big stack, but then am not playing it for the A.

like the flop bet (not so much the size. A bit bigger) to try and take the pot, or to take the river card for free with his check and me in position, hence checking the turn.

as played checking the river. V obv? has something better then A high judging by his c/calling and is not folding.

On the Turn I like a bet closer to $40. And then another large River bet. Flop bet is fine imo

This sounds about right to me. While sometimes 2+2 posters make fun of calling stations, the reality is that when a station calls, it is rarely with NOTHING. It might be something weak (such as a pair of 9s with a flush draw), but it is rarely NOTHING.

If you're barreling, you have to go a bit bigger. Otherwise you're value betting yourself.

OP my question is what is your bet on the turn actually trying to accomplish? You bet $16 into a $37 dollar pot. You are laying over 3:1 odds for villain to continue. I think if you are going to fire a bet it needs to be in the $35-$40 range.
