I think everyone else already did a good job of going over some good "as played" lines so I won't go into that but looking at the hand, it seems you may lack basic fundamentals/have big leaks if this is anywhere near a standard play for you.
Just remember that before you make a play pre flop, you understand
why and also have some plans for how you will be playing post flop. With your hand I would have a few of these things going on in my head:
1. 1 limper and it is folded to me, I have the button with a Kxss (K
2
), I can be sure I am ahead of the blinds (100% range) and I will also be setting up for profitable future steal spots with
initiative by raising. Stealing the dead pre flop money (blinds and limper)
could (it depends) by itself be profitable so even more reason to raise (if we raised and just insta-gave up if called)
2. classify your villains correctly, if someone is limping A
Q
from UTG I would label them as a PASSIVE player not TAG (T=tight AG=aggressive). You did correctly notice he was tight so he would be tight and
passive, this player type is generally labeled a
weak-tight player.
3. Without further info I am going to assume the blinds are also
weak-tight or
Loose-passive (which you said lots of limping from the table so not a bad assumption) so I feel comfortable enough with post flop actions I can make a profit with a raise rather than a limp.
3a) If they are fit fold (usually from the weak-tight villains) I can go for good steal spots with a cbet (Axx Qxx dry boards some xxx boards for example) and actually some value spots vs loose-passives since their range should be weak with mid pairs, etc. (Kxx boards and luck box 22x or boards). Now notice that by limping you can only do the latter (luck box a flop or otherwise you flop a 2 or weak king and can't play it for max value)
NOTE: There will be a lot of variables that will determine which boards to bet and not which will be too complicated to go over in this post but some good COTW should help. The cbet example I provided was crude and unsophisticated. (we can all always brush up on our post flop game).
NOTE: With your stack size, it makes stealing a little more marginal as your hand is not a pure value hand, you may have to commit lighter/bluff shove turns lighter, etc which is harder to do if you don't know the hows and whys. IT HELPS TO HAVE 100bb stacks (deeper) so top off and stay that way so you have room to open wider from late positions, otherwise if you want to play <100bbs, tighten up and stay away from the K
2
and speculative hands. Basically, you are limiting the amount of profitable spots available by being shorter.
Hope this helps you think about your pre flop and post flop planning a little more.
