A-A will beat 2 opponent 73% of time............All Aproximates.
A-A...............3..............64%.........
A-A...............4..............56%........
A-A...............5...............49%.......... Should you fold v 5 oppo"s? No..............
Play 100 hands. Win 49 times, say at $10 to win 49 x $50...= $2450
......................Lose 51 times............$10 x 51..................= $510
You come out a winner to the tune of $1940, over 100 hands, so even though you are a 49% slight dog, in this situation you have a +ev of $19.40 per hand for your $10 bet, almost 2-1.
Now AK v 1 opponent wins 65% of time, whereas against just 2 oppo"s your down to approx 48%, so against 3 or 4, it"s really not looking a good prospect. This is without considering any holdings of AA, KK or another also holding AK v the QQ and 99. Definate laydown for me here.
However last hand of $5 rebuy, i just (25 mins ago) went All in with A_K.
I didn"t want to rebuy, my stack was 2800, blinds 300/600 for the next 45 seconds anyway b4 the break.
utg +1 fold, next All in for 1500, i see this as steal/ similar thoughts to rebuying also? I re raise All in for 2800, 3 callers all with rubbish, except the BB who for the past half hour went All in and called all ins with absolute trash. He A-Q, I"m ahead chance of winning 9k+, nice stack for the freeze out section. Unfortunately A-q made a str8. Still, i felt right pushing here, the hands proved it, Also proved it"s vulnerability against multiple hands.
Hope this helps some.
