The Ten Biggest Mistakes a Poker Player Makes

[Talking Poker]

What a great thread. Sorry I'm late to the party....

For me, the answer is a very simple and specific one. I don't know if it's worthy of the overall list, but for limit players, this is HUGE (literally the difference between being a winning player and a losing player a lot of times):

-Betting the river with a medium strength hand when first to act. CHECK AND CALL, CHECK AND CALL.

Also, another huge one for limit poker:

-Calling too often on the turn; Folding too often on the river. We all know what pot odds are, but SO MANY people obviously don't understand them and how they apply when making that river decision. If you are getting 10:1 or better against just one oppponent on the river, I'll go so far as to say it is almost never correct to fold, unless you have a completely busted draw.... Calling with Ace high, and certainly any pair is often the correct play, even though it "feels" like you are losing so many showdowns. Remember, you only need to win 10% of them for that call to be correct!

Another small one (not Top 10 worthy, probably):

-Drawing to the sucker end of a straight (or any other situation where you have high negative implied odds). Even if the "pot odds" tell you calling is correct, your negative implied odds often greatly outweight the pot odds, and make drawing -EV.

I also think the bankroll management is HUGE.... Maybe lump it in with Emotional Control, but it has to be in there somewhere.
