The Block Bet
http://ezinearticles.com/?Poker-Moves-- ... &id=723789Its its basic form, is a bet that will make the larger stack be confused about your hand. And will more than likely call.
If you can put him on top pair, and if the hand played out normally, if you checked he would bet largish. The block bet pretty much cancels that the large bet, and leaves you in a position to play out the hand.
E.g Blinds 25/50. Player A raises to 200. You call. 400 in pot.
Flop comes down. Your chasing a straight (8 outs). you know your opponent has top pair. Betting a reasonable amount i.e 200 to 400. Will make the player stop and call, unless he has hit trips. then he will re raise, and you can get out of the hand relatively cheaply.
But if he just calls. Gives you the opportunity on later streets to steal a pot. Try it online a few times. Bet when everyone has checked the turn (3/4 pot). and Bet again on the river. People fold when they have missed their draws.
It works, however in pub poker is negated by the top pair all in move.

I have found with low pockets and low cards. Is that if you know a lot of the players at the table are poker smart. Then low cards can get more money on the hit and draws. Also if there is hardly any preflop raising being done. Great way to get good odds for drawing on people.
As Garth said being able to get good reads on opponents is good. ( i really do lack in this area, more cards and maths inclined). Being able to know what to do with that read is more important.
Plus the one that turns good poker players into great poker players. Is the ability to fold a hand when you know its beat, rather than call and be proved right (you can and should do this in deep stack tourneys, more information you have about a player the better).
Sidenote regarding the block bet. The raise preflop can also be used to mask you hand, You might have low cards and feel confident in people calling but not reraising you. This can set off an impression that your hand is stronger than it is. Which gives you valuable options on a high board or when you have flopped two pair gives you the ability to get max value out of your hand.
Say 3 6 suited. 25/50 levels. stacks all around the 2000 mark. 4 limpers. Raise to 200. 4 callers. (250 pot, now at 1000).
Two different flop scenarios.
Flop A 9 4. Bet of 300-400 on flop, can leave you with the pot then and there.
Flop 3 6 Q. Bet of 300-400 can show who has the queen. Get some money in on later streets.
Mind you i do play a little too agressive.
cheers,
Brett.
