4bet range for hero interesting, could def see a flat w/ AA occasionally (maybe 25%) as the flatter is a weak player, want to keep him in, but usually happy to 4bet. KK,QQ mandatory 4bet, JJ very close, AKo mandatory, AKs could go either way.

As for 4bet bluffs, think randomising my suited A wheels makes sense. Not sure what % i should randomize, so any help on that would be great. Also AQo would be a good candidate, but should also probably be randomized between flatting and 4betting, so as not to get too out of hand.

Not sure about cbetting flop, maybe check jamming is better, often get a free turn, easy to balance with AA,KK occasionally.

Turn, looking for a free card, could bet but not sure. Very sticky spot.

River, mandatory shove.
I have 11 combos of AK, some randomized number of AQo, if i dont shove turn with them, occasional AA,KK but they usually jam turn. Approx. 15 value combos, therefore given price otr, need 5 bluff combos.

We are randomizing our suited A-wheel combos as 4bets or folds preflop, and the spade versions of those combos jam turn, that leave 11 suited Awheel combos on this board, maybe randomized at around 50% preflop, giving us 5.5 possible bluff combos otr.

All of these hands must jam river to remain reasonably balanced. (3:1 value/bluff ratio required, given half pot river jam).

I look forward to your thoughts on this hand, and advice on good randomisation % so as to remain balanced pre, and how to improve the structure of the game tree postflop.
