I managed to loose my stack with 99. I think I played this terribly. I nearly didn't post the hand out of embarrassment.

I considered folding pre-flop but I decided to go set mining out of position. Probably a mistake. Marginal anyway.

After the flop, I figured I might be able to make him fold if he had a hand like AK.

The thing was, I had been hitting so many hands that I got a little carried away. Is there such a thing a "Winning Tilt" as opposed to "Losing Tilt"?

Hero (UTG) ($10.30)
MP ($10)
CO ($10)
Button ($14.40)
SB ($10)
BB ($25.90)

Preflop: Hero is UTG with 9, 9
Hero bets $0.40, 1 fold, CO raises to $1.20, Button calls $1.20, 2 folds, Hero calls $0.80

Flop: ($3.75) 5, Q, Q (3 players)
Hero checks, CO bets $2.90, 1 fold, Hero raises to $9.10 (All-In), CO calls $5.90 (All-In)

Turn: ($21.35) 3 (2 players, 2 all-in)

River: ($21.35) K (2 players, 2 all-in)

Results:
Hero had 9, 9 (two pair, Queens and nines).
CO had K, K (full house, Kings over Queens).
Outcome: CO won $20.30

I put this hand into poker stove to get some additional data.

My opponent was 23:10:5 vpip:pfr:3bet so I can assume that he has a strong hand. According to poker stove, the top 5% of hands are 88+, AJs+, KQs, and AKo.

After the flop, poker stove tells me that I am a 63:37 dog against his range.

But what does this mean? Should I have smooth called his bet and seen if I improved on the turn?

IMO dude, you played the hand ok. I mean, in a heads up sng I would play it exactly the same, although you're probably best getting Atta and HG's opinion in terms of cash.

With regards to winning tilt ... YES YES YES!!!

In fact, not long ago I saw an article about it, i think on p5's but dont remember who it was who wrote it. But the general jist of it is that you begin to think you are unbeatable and it happens to us all.

winning tilt, yeppers exactly as Matt said
atta has mentioned it happening to him as well

as to the hand,i agree w matt in the sng game, in my old sng days i would have gotten it in on the flop in a heads up situation as the last 2 standing in a 10 mn sng, which basically the same as a HU sng

In a micro cash game i would play it a bit differently
i would fold if no one called the 3 bet before it gets back to you- calling 3 bets w med prs is a no no-especially oop
with the 2 other full + stacks im ok with call preflop, but i might fold if they were both loosish players due to less chance they will have a hand to stack off vs 999, i would definitely call if both tightish, better chance they have AA KK QQ AK AQ and will have a hand they will stackoff to 999.

on the flop my normal play is to lead or fold vs most players lead betmostly the latter(fyi-typically i would check behind)- , the reason being i am not heavily invested and if i call flop and dont catch my 1/22 chance at a 9, villian could have AA KK AQ KQ JJ TT, do i want to call another bet on turn and/or river, plus any A , K , J, T further weakens my hand if it hits the turn or river- i need a good read on a player to be prepared to call down to the river, if you arent prepared to call to river, dont start down the path

what kind of read, aggr by street is where i look first, looking for something like 3.0+ flop,1.2 or less on turn and river-
these are 1 stab type players, the lower turn and river aggr the better, if they check turn they will likely check river too- they may have 22+,AK,Qx, or total rubbish, but you have a chance to get to showdown cheap

also notice the 2.90 bet is same as calling 4xbb raises preflop 7+ times, which is more likely to work out good
7 shots at a set, or the 99 being best and holding up- this type of analysis helped keep me out of trouble at micros
although i didnt use it above the 25nl games- it is basically a wait for value patience argument
i would be way more inclined to call a 1/2 pot type feeler bet and reevaluate the turn

other type thoughts that kept me out of trouble when i was sarting out
would i be willing to stack off w 99 vs 2 players w/o improving in a 3 bet pot- i hope this wasnt the plan
set mining - no set, no bet unless i pick up a draw, or have overpair to board, or board is J or T hi less likely in 3 bet range than A K or Q

that is my 2 cents

hg

just final thought of clarity what are chances niether villian has AA KK QQ AQ KQ JJ TT in a 3 bet pot- again the HM stats and 3 bet range are helpful
not trying to bluff in micros games is one of the 3 key tenets of beating micros per previous posts
i know it is tempting, but just doesnt work enough to be profitable in the micros
