In my last blog entry, I wrote about a couple of basic online poker tells. Like I said in that entry, these tells shouldn't really be new to you if you are an experienced online player; they're meant to be representative of the several dozen other tells exactly like those two. In fact, except for the better HSNL regulars and the best tourney pros, almost everyone gives off tells via their timing and betting patterns in almost every hand they play. This time around, I want to give out some tips on how to take advantage of that.
First, let's talk for a bit about preflop tells. These are more important for tournaments, but do tend to show up vs. shortstackers in cash games, as well. The majority break down into two categories:
1)Oversized raises
2)The speed of the preflop action
Oversized raises are obviously the easiest ones to spot and are almost always accurate (that is, few people fake a 4x raise; even if they do, sooner or later, some short stack will reraise them anyway and their faking will be uncovered.) I'll make it simple: most of the time, a bigger than normal raise is AK, QQ-88. Sometimes, it's AA-KK, especially when a low stakes player makes it deep into a big tournament. Overbet pushes (when someone just shoves 20-30 BB, especially with no limpers) tend to be a shade weaker - something like AK-AJs, JJ-77. Keep in mind that a good player shoving 20 BB after several limpers will often have something worse, though, and a 10-12 BB late game shove is also quite different/depends on position.
The speed of the action - especially a preflop call - also sometimes means something. This is quite a bit trickier to spot, is not nearly as accurate as bet sizing, and needs experience to get it right, so I won't go too deeply into it. One thing you can take on faith, though: if a bad player autocalls (that is, checks the 'call a raise' button) a PF raise with medium or deep stacks, it is a hand that he will play no matter what, but not a monster or anything special. Look for small pairs, small to medium suited connectors, or two 'not so great' big cards like ATo/KJo. These same players will quickly call with any pair postflop, and will stack off with top pair, but they'll need to think when calling with overcards or a gutshot.
Taking advantage of these should be self-explanatory, so let's move on to postflop tells. Most of the time I see decent - but not great - players lose tons of chips or bust out of a tournament *early* is when they ignore an obvious tell coming from a horrible player. I'm not going to list individual tells - there are too many and I'd like to be able to play poker afterwards without having to adjust all over the place - but here are some things decent players should do far more than they do:
1)Raise blocking bets. When somebody bets 100 chips into a 1000 chip pot, a raise to 1000 - or even 800 - must work < 50% of the time to show a profit. Very few people betting 100 into 1000 know anything about poker, so that bet is almost always what it seems - scared money. (Even if you get called here, you should sometimes follow through on the turn for the same reason.) Once in a great while, you'll run into an exception, get minimum 3 bet, make a note of it and move on; next time, you can fold top 2 pair to his set.
2)Pay attention to the flop bet. When a decent, straightforward player raises, gets 5 calls, and then bets a decent amount into the field on an 8

flop, your nines are no good. Don't even bother to call the flop bet to 'see where you are' or any of that nonsense. Yes, you have an overpair, and yes, sometimes he will merely have a flush draw - but that doesn't mean anything. You're still a giant dog to his range and losing tons of money on the call, so just fold. (However, if you're deep stacked and have implied odds, sometimes you should take a card off with a hand like 43, even when you'd fold 99. See below.)
3)Pay attention to the flop bet, the flip side: When that same player bets big in a 6 way pot, you can assume he has at least an overpair or a big flush draw. If you have a set, calling is almost always a bad play. Why? Sometimes, an ace will hit the turn when the other guy has kings (and so on down the line); sometimes, the third flush card will hit and kill your action/hand; sometimes, you'll make a boat with the second 8 and freeze him up...and so on.
Bottom line: in multiway pots, when somebody's hand is face up as a big pair, it is very rarely correct to slowplay your monster. There are only a few exceptions, such as when you're second to act and there's a couple of maniacs behind you, or when the guy is good enough to make a tough fold if you raise the flop but will commit himself on the turn.
3.5)When and how to try to crack that big pair: Mediocre players will often just raise every draw, including hands like J

T

, on the flop, thinking "flush draw + overcards + fold equity". Big mistake. His bet told you that he isn't folding and probably has an overpair, so why are you counting any fold equity *or* overcards as outs? More often, it's correct to just call and go for overcalls - reserving the right to semibluff raise on the turn, especially if a J or T hits. Conversely, if you have that 43 on the 832 flop I mentioned earlier and are closing the action, you should sometimes also call even when definitely behind, looking for a "brick" 3 on the turn. In HSNL against thinking opponents, you would also look for aces and fives and occasionally semibluff those cards, too. (But do *not* usually call with aces, such as A3 on an 832 flop, when facing a certain big pair - your implied odds simply don't exist.)
That generally covers "what to do if villain has what he thinks is the nuts." Next time, I'll write about a few ways to take advantage when the villain telegraphs a weaker hand.
