A poker update: Online & live

I've tried playing a lot more online this week, with varying degrees of success. Overall I'm slightly ahead (and by slightly I mean <$20 ahead), but I'm really struggling to come to grips with the differences between live & online play. The extra hands & multi-tabling hasn't been much of a problem as I've only been playing limit poker (mostly holdem, though I did manage about an hour of 2-7 triple draw as well), so its simply fold, call/check, bet/raise ... no need to concern myself with how much to bet or raise, stack sizes, stack-to-pot ratios, and other assorted issues of no limit holdem. The main issue for me at the moment is using a HUD. I briefly used a HUD when I was playing about 1.5-2 years ago, but I was only playing one table at a time then & online poker developed into more of a thing to pass the time rather than a serious money-making venture, so I didn't feel there was much of a need. Obviously since then, and adding the fact that I want to take my online poker more seriously, I realised that a HUD would be something necessary in order for me to progress online. With this new development comes issue ... yes, I now have a bunch of numbers on my opponents at the table ... the issue is how to use that information - what do the numbers mean, how do they help categorise opponents, how can they be used to develop ranges for opponents, etc. I feel like I need to re-learn poker for this 'new' environment.
Guess its something for the future ...
The other issues with online poker are two-fold ... I'm on a computer with the internet running ... this means that distractions are literally a mouse-click away ... whether it is Facebook, YouTube, ICC (chess), Settlers of Catan or something else, there's always the possibility of doing something else immediately ... I suppose this issue can be solved by discipline & making sure that when I'm playing poker, that is all I'm doing!
The other issue is that live poker is so much more profitable! Add in the fact that its something I'm far more comfortable with & it seems like a no-brainer! Why slave away in front of a computer for hours, only to come away say $30 to the good (and of course the money is 'online', with further hoops & hurdles to overcome before it becomes cash in hand), when you can go for a drive to the casino & do nothing special & almost definitely lock up a win of some kind, which is often in the $300+ mark.
This leads me into a big hand I played tonight at Crown int he $2/3NL game.
There was a limp from UTG+1, limp from the hijack & I raised in the cutoff to $12 with AcQd. The button, SB, BB & the two limpers all called to make it 6 to the flop. KcJc6s & it is checked through. I didn't feel the need to c-bet on this flop as I'm only going to get called by a hand that I'm behind & there are a lot of cards that could get me in trouble on the tun if I were to bet & inflate the pot with just ace-high.
Anyway, the turn is the Tc, so there is a flush possible, though I now have a broadway straight (with the re-draw to the nut straight). Of course at the time I didn't realise I had the Ac ... I just knew I had Aqo & had turned broadway. Anyway, it is checked to the hijack (an old guy who had been playing fairly snugly) who bet $15. I raised to $35 & was called by the SB (a regular in the 2/3 game who is a decent, solid player, but also capable of making a move from time to time). The old guy folds & we are heads-up to the river.
The river is the 2c, making the final board KcJc6sTc2c. The SB now leads out for $60! I tried to remain composed as I re-raised to $130. The SB thought for a little while and then moved all-in! I had about $275 behind & he had me covered! I considered my options ... I had the nut flush right? No paired board ... what could beat me? Qc9c? That was it. Could he have the straight flush? I actually said out load 'do you *really* have Q9 of clubs?' & after another 10 seconds thought said 'call' ... only to be shown the hand I feared ... Qc9c for a straight flush! Ouch!
With the value of hindsight, I should have been able to either a) just call the river (yes, a sick call, but a good one); or b) fold to the shove (and be really sick & fold the Ac face-up!). What makes me say this? Simply because we have played with each other before & I respect his game & he seemed to respect my game. With the Ac in my hand & the K, J & T of clubs on the board ... what POSSIBLE hand could he be betting the river with? After I have shown strength from the turn & river (as well as pre-flop), could he REALLY be confident betting the river with just the bare Qc? Possible, but unlikely. With no paired board, there is no full house possibility ... and he did just check-call 2 bets on the turn & lead the river ... end result: he MUST have either the straight flush or air ... and is looks like a really bad board to be betting air! Guess that was my Mike McDermott moment for the evening ... I didn't properly think through the hand at the time & it cost me a big pot. I managed to win much of what I had lost in that pot back by the end of the night, but still left slightly down for the evening. Oh well ... guess I'll think it through better next time!
