How often does your "ALL-IN" fail pre-flop and why?

Prefer to go all in, with coverage..

All-in is the ultimate risk, unless you have enough of a stack to have the table "covered", even if everybody at table went all-in, and you did as well, you'd survive.
In this situation, it's more bullying than taking a risk. With bullying, there is the risk that some smaller stacks don't like bullies and fight back

I try to avoid the all-ins preflop, especially early in an MTT, unless I have a monster pair and know the player shoving is doing so with a wide range. Even then, you will still lose on occasion so It's not something I make a habit of doing. Prefer to play the flop. At least you have some idea of where you stand in the hand!

My 2 all-in at the start of the session. :boxing:

I think I hit about 75% I am very cautious about my all in pre flop and don't like to lose my chips
