He seems like a a pretty solid LAG. He has done moves on bluffspots a couple times earlier.

This is an earlier hand:

t15/t30 Blinds

BTN/SB: t1620 54 BBs
Hero (BB): t1380 46 BBs

Pre Flop: (t45) Hero is BB with 7 5
BTN/SB calls t15, Hero checks

Flop: (t60) 2 7 8 (2 players)
Hero checks, BTN/SB checks

Turn: (t60) A (2 players)
Hero checks, BTN/SB bets t90, Hero calls t90

River: (t240) 4 (2 players)
Hero checks, BTN/SB checks

Final Pot: t240
BTN/SB mucks 4 3
Hero shows 7 5 (a pair of Sevens)
Hero wins t240


The actual hand:

t25/t50 Blinds

BTN/SB: t1690 33.80 BBs
Hero (BB): t1310 26.20 BBs

Pre Flop: (t75) Hero is BB with A 8
BTN/SB raises to t100, Hero calls t50

Flop: (t200) 3 A 5 (2 players)
Hero checks, BTN/SB bets t200, Hero calls t200

Turn: (t600) 7 (2 players)
Hero checks, BTN/SB checks

River: (t600) 6 (2 players)
Hero bets t300

I believe he would cbet turn if he had a flushdraw or a flush. I've only made one river valubet before and I made it little less than half pot.

Got any more reads postflop?

His overbet on hand 1 is kinda stupid.

Hand 2, if he's raising wide preflop it's an easy shove with ~26bb. Flatting is ok too, just depends on your evaluation of his postflop play and how profitable it is for you to play this hand against him. Anyways, flop is a bad spot to flat, you have 24 bb left in an 8bb pot after he pots it, just raise and get it in and expect to be ahead against draws and middle pairs often. As played, I'd just c/f river, no sense turning your hand into a bluff when he's likely to checkdown his showdown value anyway.

Didn't ad to many reads since I wanted a more general opinon on the hand, not finding blufspots is a leak I have.

He bets draws, always bets river if I have shown weakness, the times he has done a pot sized cbet it has been when he has a weaker hand, like bottom pair.

^^
this is all the more reason to raise. if you check to him he's just going to try to get to show down and is unlikely to turn a made and into a bluff here.

26bbs deep, A8s, anyone else like 3b/calling pre or simply shoving pre? Seems better than flatting but I guess that depends on how spewy/bluff happy villain is, and whether we can get to a lot of SD's with just ace high comfortably.

This is a good thing to know about yourself, but considering this hand I think flatting (and not raising the flop when you do flat at these effective stacks) is a bigger leak - especially vs described opponent.

Also, vs Lags I usually am more concerned with maximizing value than making bluffs (though I agree with Zachaser - read dependent)
