This type of hand/spot is actually an exceptional example of where this can be used as an angle and why no aggresive action should be allowed!
Lets say the guy flips his hand over post flop. This is a spot where irrespective of what the other guy has, the villain has a tonne of equity even if he is currently behind and the other guy knows he isnt folding the flop.
So, as the villain, we know we are never folding, we know the other guy can "act perfectly given perfect information" so we Jam! we are never in a bad spot. So how is this not an angle which the villain can expolit?
What.
How are we never in a bad spot? This gives the other player a massive advantage:
- He can happily call off with his strong hands
- He can happily fold worse
- He can't end up in a situation where he decides to bluff against a player who is never folding
You say the villain has a tonne of equity post-flop. Yes, he has. But he'd have had more if the other player couldn't see the hand.
Let's take a more obviously clear cut example. You have KK and villian shows AA and is first to act. Villain is going to jam. Flops are rainbow:
1) T92
Nice easy fold for the KK. We've just saved loads of chips.
2) AK5
Another nice easy fold. We'd 100% never have folded here had we not seen his hand.
3) KT2
gg AA.
And the other assumption here is that villain is going to flop the world. This won't always be the case. Let's say the flop comes down TJQhhh. Yeah, villain is screwed.
