This was hand from my birthday session at my local casino versus a total maniac who had just come over from the other table that broke. He brought around $800-900 with him and within a few orbits (after playing 90% of the hands, clearly trying to run over the table) he was down to around $600, so it was fairly obvious that he was starting to tilt if he wasn't already. I had $363 in my stack to start the hand.

Dealt Ah Ad in BB it was folded around to the HJ(maniac) who raised to $12. CO folds and the BTN and SB call. I raise to $33 and the action is back on the maniac who tanks for about 1 minute, pulls his original bet back then slides a 20 stack of $5 chips into the middle ($100) and the BTN and SB fold.

I tank for about a minute as well trying to make it seem like I have a decision. Taking into account he is tilting and looking to win back his money I simply slide all my chips into the middle and he snap calls me. In my haste I flip my cards over instantly (forgetting you don't need to show when all in).

The board runs out Ks 2s 3c Qs 10d

At this point I am thinking I lost, but thankfully he mucks his hand as soon as the river card is dealt.

Any thoughts on how I could have approached the situation differently? I am happy with the result of the hand (obviously) just wanting to know if there was a better line that I could have taken in that situation. Also what you guys think the maniac might have had in his hand (I think AK).

Any input in appreciated, thanks for reading

I think your initial 3-bet to $33 was too small. After two callers, I'd raise to something like $60, which is a pot-sized bet, in order to maximize value and downplay your positional disadvantage by growing the pot in relation to the stacks, leaving less room to maneuver postflop. As played, after his 4bet to $100, I agree with your decision to shove; if you had position on him, an argument could be made for flatting and letting him hopefully bluff off the rest on the flop, but out of position I think a shove is clearly better. Nice hand.

Initial raise could probably be bigger but doesn't need to be much bigger. There is $38 in pot when it gets to you, I would go $40/$50 here. After that it is pretty well set. Against some villains who will stack off later in hand but fold to a shove preflop, calling might be better. Out of position against a maniac who seems to be tilting, I shove here every time.

As for what he had that you beat, that is hard to say. The obvious hands to call the shove are QQ+ and they are all beating you or chops. Everything else is a pretty obvious fold when you shove, so it is hard to build a sensible range. I would put a lot of AK and JJ in his range, some AQ and medium/small pairs and probably some suited connectors. For a lot of manics some random garbage that felt it was priced in after making a bluff raise to $100 is probably in range also.

Grunch:

you're 3 bet size was atrocious. $50 at least.

Otherwise, well let's see. You got all your money in the middle with AA preflop. I'd say you did just fine.

As I said in the start of the post it was my birthday (19th) session and was my first true live experience playing at a casino and looking down at bullets kind of got into my head. I didn't want to chase any action away so i 3bet fairly small in relation to the pot. To be honest I regretted the sizing after he had put out the 4bet, because in my mind it looks like when I 5bet shove for another $263 I was trying to induce all along. However I will pay much closer attention to my 3bet sizing in the future and not be so worried about trying to get action with bullets
