Regarding the buy-in full argument, I am in complete agreement and I have a couple funny hands showing how bad people are at deep stack.
1) 1/2 NL around 2AM, stacks had gotten very deep
V1: UTG+1, friend of mine, MAWG, running extremely good, sitting on 2k+
V2: SB, fish running good, not a terrible player with 100BB stacks but clueless deep, sitting on about 1k
H: MP, 30ish WG, TAG, built up about 1.2k over past 8 hours
Other villains: Stacks vary but almost everyone has 500+ and there are no strong players besides me and V1. Most are way too loose pre-flop.
I have T
T
MP
V1 opens to 10 UTG+1, I 3-bet to 35 in MP, HJ calls, BTN calls, SB tosses out a black chip which is immediately ruled a call. He throws a fit saying it's a raise, gets the supervisor involved. It's ruled a call. SB looks mad. BB calls, and UTG+1 calls.
Flop (210) K
9
3
I'm watching HJ and BTN as it's dealt and they don't look too interested. I hear SB announce all-in as soon as the K is shown, and he then mumbles something like "I hit that flop hard". I'm 99% sure he's FOS and considering calling with just my TT when UTG+1 throws a chip forward. I know he'll call pretty light but he has at least a K here so I fold as do the others. Turn and river brick.
UTG+1 shows A
K
, SB mucks face-up (by accident I think) A
Q
and storms away from the table. The biggest 1/2 pot I've seen to date gets shipped to my friend who now has so many red chips he's built a huge pyramid (base is like 9 stacks wide).
It was a pretty funny hand. I just wish I'd been the one to hero call.
2) 5/T NL, at the must-move table, a lot of players waiting on a T/25 game
Note: This hand is a bad beat but I'm including it to show how bad some players are deep, even in higher stakes games.
H: 30ish WG, have been at table less than an hour but my image should be pretty TAG. I bought in max (2500) and have won a few pots, now have about 3.2k
V: MAWG, Bad LAG, has PFR around 40, hyper-aggressive post-flop to the point of being spewy, but has managed to blow some people off their hands and build his stack a bit. I think he's waiting on T/25. He has about 3k.
I'm in the BB with 7
5
Folds to V OTB who opens to 30. I could 3-bet but figure he's calling too much and I don't want to get 4-bet either. So I just call.
Flop (65) 4

8
Jackpot. I expect this villain to C-bet 1000% so I x. He c-bets 40 and I x/r to 200. V calls. At this point I'm assuming he has a SD, 2p, maybe an OP.
Turn (465) 4

Great card for me as it improves a lot of this guy's range and I still have the nuts. Again I check fully expecting him to bet again. V bets 300. Again I x/r, this time to 900. V thinks about 5s then rips it in for 1800 more! I'm pretty confused as to what he could possibly have. I figure he must have a set. I tell him I have the nuts as I toss forward a chip to call. He responds "Big draw".
River (5865) 4

I don't love it and am still processing what he meant by "big draw" but I have two hearts so I turn up my hand and he turns up K
2
and wins the biggest pot I've been involved in. I don't get mad or anything. It's so absurd I just chuckle to myself.
But the point is...his hyper-aggressive play is just horrific vs. a tight player who has shown tremendous strength. Why is he calling OTF? He has K-high and backdoor draws. He has like zero FE OTT after I x/r TWICE. But he still rips it in with a naked FD. Although I lost this hand and haven't played 5/T since due to not having the roll for it, I take solace in the fact there are horrific players at every level, basically just giving away their money in deep-stacked situations where they don't understand the level of hand strength they actually need to play that way.
So... buy in full! Top off continuously. You do lose huge pots like the above occasionally, but 80-90 percent of the time you should be on the winning end when the money goes in 300BB+ deep.
