[The Odds God]

hand 1: I raise river, close though.

hand 2: easy river raise, looks more like a block bet than the first one, like he is scared of a raise

hand 3: I push turn.

1) I don't like the double barrel. There's lots of Qx in his range the T isn't really a scare card and we have very little equity when called.

I probably raise the river as played though because I think his hand is weak.

2) I fold here because I think he made aces up or Acxc spiked a lot. 45s also got there.

3) I c/f flop. It smacks his range hard and he doesn't like folding anyway.

I feel like such a nit.

My approch to the game and particularly the opponents described is different.

If you're going to jam so much post-flop open for more money.
