AK vs 22 we are in a coin flip (Coin Flip is a situation where two players have approximately the same chances of winning a certain pot), when we are allin.
The coin flip with pairs will be approximated up to the pair of 88 (we will have almost the same chances).
*Tip: When we are at the beginning of a tournament (deepstack) we always play smaller pairs for the set value (three of a kind value). a set on the flop).
Then we use the coin flip a lot when we have a lot of chips and call or isolomaos shoves(allinn) small 7 to 11bb depending on our stack!.
Then we use a lot to apply shoves first (first to go allin), or as a resteal vs rease of final positions ex.. we are in smal or big butom opens rease for stealing blinds (we usually shove these pairs with stacks up to 15bigblinds.
below are some percentages AK vs 22 and AK vs 88 ..... showing that the values are almost similar to apply to played with them! glglgl bro.
