Some nice little money making tricks
Here are a few
1. When you have a big straight on the river. For example, say you have King 9 and the board is 4 5 6 7 8. There has been a small preflop raise and you called, so the pot is still kinda small. On the turn he checks, you check behind him. On the river he checks. Now you wait a little bit use up some time. Then you make a huge out of line bigger than pot bet. Bet like 2x or 3x the size of the pot. Your opponent will almost always call thinking he'll split the pot with you. This happened to me yesterday and I found it amusing.
2. The board is 5 6 7 8 9 and he checks on the river. The pot is medium sized. Go all in or make a bigger than pot bet. You will be in big trouble if he was trapping you with a 10, but if he had a 10 he would have probably bet the river. So now he's in a tough spot. He can jepordize a lot of chips to call and split the pot, or he might think you have the 10, and fold, so you win a decent pot that you otherwise would have split.
3. You've been caught bluffing recently. You raise in early position with a small pair. One or two players call you. You flop quads or you flop a set with no straight or flush draws on board. Then you make a big pot sized bet. Hopefully you'll get a caller or two. Then you check on the turn. Now they will believe you have ace high or king high, and were bluffing on the flop and you can often win an extra bet on the river or turn.
These situations don't come up often but these are good plays when these situations do come up.
