Beginner advice: checking top-pair/top-kicker instead of c-betting
If you use discretion, you can find good poker advice on Youtube (yes I know there's a lot of crap there, but some
advice is good)
One that I particularly like discusses my big biggest leak: playing a good one-pair ..in this case when to check TPTK out-of-position
(instead of c-betting like I normally would).
I know this example is obvious to experienced players, but most beginners would bet their TPTK here.
A different example is to check any
made-hand on a very dry flop like J74r (even an over-pair or set!). The idea here is to disguise your strength.
