Hero is MP with Kh2sKsAh

Multiway a bet is for sure in order. You draw to the nuts, block the outs of other hands that draw to straights and you have decent equity even against the nuts.
But I dont like your sizing. After betting this big, some players may fold weaker draws and the whole point of a bet on the flop multiway is to make worse draws call to draw to inferior holding.

If it was heads up, a big bet is ok because you want to put alot of pressure on your oponent's naked showdown value like T8 that actually beats you. Plus, the big bet may seem like a strong hand without redraws and he may continue with weaker draws regardless of the sizing because its a heads up pot. Theres a point to be made about a small bet HU also... I dont think you can go wrong either way.

Thank you so much.

I like the way this hand is played. When hero cbets against 3 player on really wet board, it doesn't really matter if hero bets 75% or 100% of pot. Hero has a hand and is willing to play for his stack.

Pot flop, shove turn.

What about 30 to 50% to invite weaker draws?

SPR 2,5 so I don't think it affects calling frequencies that much. It's a multiway pot, basicly people get the money in or they don't. If hero bets half a pot and gets one caller, it would be SPR 1 on the turn. Those weak draws can fold then. Now when the SPR is 0,5 those weak draws will not fold.

As a rule of thumb (especially from weaker players) it's easier to get a call from a draw on the flop than on the turn.

I also like it as played. It's nice to be able to have enough equity vs any range to commit right now to the pot. If we force people off their equity with a big bet, so be it
