I bet the turn for 2 reasons. 1. To fold any unpaired Ax hands that might still be around. 2. I thought it was +ev if I got 3 callers, but I realised that was wrong after looking over the hand.

Both these reasons are wrong.

1. Even if a bet fold a better ace every time it would be -EV. By folding an A you're buying 2 outs which will only come in 4% of the time. You're buying 4% of the pot. 0.04*11.25= 0.45
You're investing one BB to win at best 0.45BB (in reality less than 0.2BB since you'll not often fold a better ace here).

2. As you said, this is just plain wrong.

Take the turn free card.

But think about it, when you have people fold you increase your chance of winning the pot greatly.

Not to sound like a parrot, but I agree. It's just that betting here isn't as obvious (to me) as raising pf or flop was.

Actually ignore my first post, I would bet here. You have about a 20% chance of improving to the nuts and if you spike an ace you might win. Since you're contributing 20% of the pot, you should bet. Betting would be better than taking the free card.

I'll give you at best 23% equity here. You'll have to get ALL four players calling for a bet almost every time for it to be +EV. Take the freecard.

Turn is debatable. A free card here would be nice, but the pot may be big enough to try and knock out a player or two.

Unless you can get a better hand to fold by betting (won't happen often) you don't want to knock out players by betting.

If I check and catch an ace on the river, I won't be happy if it's a bet and 2 calls (or worse) to me.

[/ QUOTE ]
Why? It's an easy call.

This is wracking my brain. Thanks for the input.

No. You improve your chances a tiny bit. Not worth a bet.

Meh I may very well be wrong. We need Shillx here to run some numbers.

If a bet won't improve your chances in winning the hand unimproved (it will not) it's wrong to bet to fold opponents. And since you'll not get 4 callers most of the time either it will be wrong to bet because of your ~23% equity.

Another (small) advantage of checking is that somebody might bet into you when you river the flush.

I think it was better to bet the turn and may be get free showdown.

You don't want a free showdown with A-high.
