Luckily I wasn't in this hand but looking for comments on facing a hyper-aggressive LAG.

Hand played in aggressive 2-5 Vegas game with most players around 1k. Young LAG reg ($800)opens for 25 in MP, SB calls and Hyper LAG in BB (2K) makes it 125, SB folds, original caller calls.

Flop: (275) Kc6h2s BB makes it $300 and MB calls.
Turn: (875) BB goes all-in, MB tanks and calls.
Riv: 2h: BB shows 92o and scoops pot with trip 2s.

Clearly he was representing AA, AK or KK, and also stated he would have shoved any river. What is a strategy against a player who makes moves I would never consider? I basically stay tighter than normal, in-position, and look at probable range, but range was certainly not a factor in this hand.

Note: The hyper LAG is a Vegas 30ish reg, not a maniac.

shoving the river after you've already gone all in because you think you have fold equity is a really high level play only serious vegas regs know.

it would be somewhat relevant to know what the turn was here but obv the strategy is to call off your broadway kings on the turn here and lose dat money when the maniac hits a five outer on the river.

first bit of strategy is to be properly rolled or even overolled. playing in a game like this you're going to have swings that are more like a 5/10 uncapped than a 2/5 capped game.

one adjustment I would make is to start backraising PF a lot more often. i don't backraise PF very often in a "normal" game but with a player like this I'm going to be doing it with a pretty wide range. for example, the SB should absolutely never be flatting an open to fold to a 5x raise from this maniac because that is just setting money on fire. i don't know what stack SB is on but let's say I'm on $500 in this position with this player on my left I might flat 99-JJ here vs this open as well as all AK and KQs and if I flat the $25 and this player makes it $125 and then the original raiser flat calls all of those hands are getting jammed.

another adjustment to make if you have position is to go for delayed c-bets. if you flop a monster or a monster draw and the maniac checks i'm going to check it back a lot more often and see if he doesn't decide to take the lead or put in a bluff checkraise drawing semi-dead when i have him crushed on the turn.

one thing you want to avoid doing is start playing bingo and try to outmaniac the maniac. don't RFI 5x with KJo so that he can 3bet you 5x and put you in a weird spot in position, flatcall it because you think you can soul read him and then get luckboxed on the river. make smallball raises with hands that play very well postflop and 4bet for value big.

range is always a factor in every hand. if his 3bet range from the big blind is any two cards then we'd ought to be 4betting quite a lot more often.

lastly, consider the archnemesis of the maniac, old man coffee. think, what would old man coffee do? AA UTG? toss the single redbird in for the limp go back to your crossword puzzle and then slide that full $1200 stack across the felt when he makes it $275 to go with napkins because he wants to play street poker.

This is probably the most important point. The hyper lag is going to get stacks all in a lot more then you would see otherwise and with weaker hands. If your going to play you need to not give up.

If you can setup it up so your getting odds set mining hyper lags is very profitable. Because they are going to dump a lot of money into pots you won't have problems getting your money, you just have to make sure you are not paying too much preflop.

In some situations you can also limp/call against the hyper lag more rather then less. Take some hands you would open your self and limp, knowing the hyper lag will take care of betting for you.

Don't fall into the trap of calling flop with marginal hands unless you are willing to call down on most any run out. A lot of the way hyper lags make money is getting people to call big raises preflop and big bets on the flop and then give up on the turn. The hyper lag isn't going to stop barreling very often and you need to account for that when planning.

Truth is that there’s a ton of way to beat a hyper-LAG.
If u flop a strong pair just hole on.
The only thing that u ABSOLUTELY CANNOT DO is flop a decent pair, call once, call twice, and then get scared and fold to the last barrel. This is how u lose.

Thanks, all of the comments are consistent and right on: the tricky thing is being ready to play for stacks almost every hand you are in with the hyper LAG.

In general you are right. But board texture does matter. Occasionally a turn/river will roll off that gives V a whole bunch of strong hands. It can sometimes be OK to fold when a lot of draws hit. But if it's just blanks, then yeah, strap yourself in and be ready to call down. Sometimes that random offsuit 5 hits their ragged two pair and you get stacked. Rebuy and do it again.

A good maniac knows that when he makes a big bet and gets called he is up against a monster and will shut down. A bad maniac nonstop fires without any reads and doesnt care about board texture. Lumping in someone as a "hyper LAG" as if they all play the same is a very wrong approach to a scary player and the quicker you learn their betting patterns the better.

The best approach is to tighten up and play your strong hands as strong as possible until you get solid reads. If you raise 20 to 120 pre with KK and an A comes I would just flat out give up the pot for example. If the board was instead 8d7d5 I would pot it every street or even overbet the flop.
